canoe plants

One of the major human migration events was the maritime settlement of the islands of the Indo-Pacific by the Austronesian peoples, believed to have started from at least 5,500 to 4,000 BP (3500 to 2000 BCE). These migrations were accompanied by a set of domesticated, semi-domesticated, and commensal plants and animals transported via outrigger ships and catamarans that enabled early Austronesians to thrive in the islands of Maritime Southeast Asia (also known as 'Island Southeast Asia'. e.g.: Philippines, Indonesia), Near Oceania (Melanesia), Remote Oceania (Micronesia and Polynesia), Madagascar, and the Comoros Islands.

They include crops and animals believed to have originated from the Hemudu and Majiabang cultures in the hypothetical pre-Austronesian homelands in mainland China, as well as other plants and animals believed to have been first domesticated from within Taiwan, Maritime Southeast Asia, and New Guinea. Some of these plants are sometimes also known as "canoe plants", especially in the context of the Polynesian migrations. Domesticated animals and plants introduced during historic times are not included.

Plants

Domesticated, semi-domesticated, and commensal plants carried by Austronesian voyagers include the following:

''Aleurites moluccanus'' (candlenut)

The candlenut ('' Aleurites moluccanus'') was first domesticated in Island Southeast Asia. Remains of harvested candlenuts have been recovered from archaeological sites in Timor and Morotai in eastern Indonesia, dated to around 13,000 BP and 11,000 BP respectively. Archaeological evidence of candlenut cultivation is also found in Neolithic sites of the Toalean culture in southern Sulawesi dated to around 3,700 to 2,300 BP. Candlenut were widely introduced into the Pacific Islands by early Austronesian voyagers and became naturalized to high volcanic islands.

Candlenut has a very wide range of uses and every part of the tree can be harvested. They were primarily cultivated for the high oil content in their nut kernels. They were used widely for illumination, prior to the introduction of other light sources, hence the name "candlenut". The kernels were skewered on coconut midribs that were then set alight. Each kernel takes about three minutes to burn and thus the series could act as a torch. This tradition of making candlenut torches exists in both Southeast Asia and Oceania. Candlenut oil extracted from the nuts can also be used directly in lamps. They can also be utilized in the production of soaps, ointments, and as preservatives for fishing gear. Other traditional uses include using the timber for making small canoes and carvings; the sap for varnish and resins; the nut shells for ornamentation (most notably as leis), fish-hooks, toys, and the production of black dyes; the bark for medicine and fiber; and so on. Some non-toxic varieties are also used as condiments or ingredients in the cuisines of Southeast Asia and the Pacific.

The Proto-Malayo-Polynesian word for candlenut is reconstructed as ''*kamiri'', with modern cognates including Hanunó'o, Iban, and Sundanese ''kamiri''; Javanese and Malay ''kemiri''; and Tetun ''kamii''. However the Oceanian words for candlenut are believed to be derived instead from Proto-Austronesian ''*CuSuR'' which became Proto-Malayo-Polynesian ''*tuhuR'', originally meaning "string together, as beads", referring to the construction of the candlenut torches. It became Proto-Eastern-Malayo-Polynesian and Proto-Oceanic ''*tuRi'' which is then reduplicated. Modern cognates including Fijian, Tongan, Rarotongan, and Niue ''tui-tui''; and Hawaiian ''kui-kui'' or ''kukui''.

''Alocasia macrorrhizos'' (giant taro)

The giant taro (''Alocasia macrorrhizos'') was originally domesticated in the Philippines, but are known from wild specimens to early Austronesians in Taiwan. From the Philippines, they spread outwards to the rest of Island Southeast Asia and eastward to Oceania where it became one of the staple crops of Pacific Islanders. They are one of the four main species of aroids (taros) cultivated by Austronesians primarily as a source of starch, the others being '' Amorphophallus paeoniifolius'', ''Colocasia esculenta'', and '' Cyrtosperma merkusii'', each with multiple cultivated varieties. Their leaves and stems are also edible if cooked thoroughly, though this is rarely done for giant taro as it contains higher amounts of raphides which cause itching.

The reconstructed word for giant taro in Proto-Austronesian is ''*biRaq'', which became Proto-Oceanic ''*piRaq''. Modern cognates for it in Island Southeast Asia and Micronesia include Rukai ''vi'a'' or ''bi'a''; Ifugao ''bila''; Ilocano, Cebuano, and Bikol ''biga''; Tiruray ''bira''; Ngaju ''biha''; Malagasy ''via''; Malay and Acehnese ''birah''; Mongondow ''biga''; Palauan ''bísə''; Chamorro ''piga''; Bima ''wia''; Roti and Tetun ''fia''; Asilulu ''hila''; and Kowiai ''fira''. In Oceania, cognates for it include Wuvulu and Aua ''pia''; Motu and 'Are'are ''hira''; Kilivila and Fijian ''via''; and Hawaiian ''pia''. Note that in some cases, the cognates have shifted to mean other types of taro.

''Amorphophallus paeoniifolius'' (elephant foot yam)

The elephant foot yam ('' Amorphophallus paeoniifolius'') is used as food in Island Southeast Asia, Mainland Southeast Asia, and South Asia. Its origin and center of domestication was formerly considered to be India, where it is most widely utilized as a food resource in recent times. But a genetic study in 2017 has shown that Indian populations of elephant foot yams have lower genetic diversity than those in Island Southeast Asia, therefore it is now believed that elephant foot yams originated from Island Southeast Asia and spread westwards into Thailand and India, resulting in three independent domestication events. From Island Southeast Asia, they were also spread even further west into Madagascar, and eastwards to coastal New Guinea and Oceania by Austronesians. Though they may have spread south into Australia without human intervention.

The elephant foot yam is one of the four main species of aroids (taros) cultivated by Austronesians primarily as a source of starch, the others being ''Alocasia macrorrhizos'', ''Colocasia esculenta'', and '' Cyrtosperma merkusii'', each with multiple cultivated varieties. Elephant foot yam, however, is the least important among the four and was likely only eaten as a famine crop, since it contains more raphides that cause irritation if not cooked thoroughly.

''Artocarpus''

Numerous species of '' Artocarpus'' are traditionally cultivated or harvested from semi-domesticated or wild populations in Island Southeast Asia and Micronesia for food, timber, traditional medicine, and other uses. They include '' Artocarpus anisophyllus'' (entawak), ''Artocarpus heterophyllus'' (jackfruit or nangka), '' Artocarpus integer'' (cempedak), '' Artocarpus lacucha'' (lakuch), '' Artocarpus mariannensis'' (Marianas breadfruit), '' Artocarpus odoratissimus'' (tarap or marang), and ''Artocarpus treculianus'' (tipuho), among many others. The most important species pertaining to the Austronesian expansion however, are '' Artocarpus camansi'' (breadnut or seeded breadfruit) and ''Artocarpus altilis'' (breadfruit).

''Artocarpus altilis'' (breadfruit)

According to DNA fingerprinting studies, the wild seeded ancestor of ''Artocarpus altilis'' is the ''Artocarpus camansi'', which is native to New Guinea, the Maluku Islands, and the Philippines. ''A. camansi'' was domesticated and selectively bred in Polynesia, giving rise to the mostly seedless ''Artocarpus altilis''. Micronesian breadfruit also show evidence of hybridization with the native ''Artocarpus mariannensis'', while most Polynesian and Melanesian cultivars do not. This indicates that Micronesia was initially colonized separately from Polynesia and Melanesia through two different migration events which later came into contact with each other in eastern Micronesia.

The reconstructed Proto-Malayo-Polynesian word for breadfruit is '' *kuluʀ'', which became Proto-Oceanic ''*kulur'' and Proto-Polynesian ''*kulu''. Modern cognates include Sundanese and Malay ''kulur'' or ''kelur''; Acehnese ''kulu''; Iban ''kurur''; Cebuano ''kulo'' or ''kolo''; Muna ''kula''; Mussau ''ulu''; Kapingamarangi ''gulu''; Wayan Fijian ''kulu''; Emae ''kuro''; Tuamotuan, Takuu, and Rarotongan ''kuru''; Tahitian ''uru''; Samoan and Hawaiian ''ulu''; and Māori ''kuru''. Note that in Māori, ''kuru'' is only mentioned in tradition, but does not refer to the plant because breadfruit did not survive into Aotearoa. Also note that it is believed that breadfruit only reached western Island Southeast Asia (Java, Sumatra, Malay Peninsula) during the recent centuries, as a result of trade with the Maluku Islands.

Another notable reconstructed word for breadfruit is Proto-Oceanic ''*maRi'' or ''*mai''. It is a common root for words for breadfruit in Micronesia, northern and western New Guinea, the Solomon Islands, the Admiralty Islands, St Matthias Islands, New Caledonia, and parts of the Central Pacific. The term itself may have originally been for ''Artocarpus mariannensis'' instead of ''Artocarpus altilis''. Cognates include Pohnpeian, Mokil, and Ngatik ''māi''; Palauan, Satawal, and Tuvaluan ''mai''; Puluwat ''mais''; Yapese ''maiyah''; and Tongan, Niuean, and Marquesan ''mei''.

''Artocarpus heterophyllus'' (jackfruit)

The jackfruit (''Artocarpus heterophyllus'') was domesticated independently in South Asia and Southeast Asia, as evidenced by the fact that the Southeast Asian names for the fruit are not derived from the Sanskrit roots. It was probably first domesticated by Austronesians in Java or the Malay Peninsula. The word for jackfruit in Proto-Western-Malayo-Polynesian is reconstructed as ''*laŋkaq''. Modern cognates include Sundanese, Javanese, Malay, Balinese, and Cebuano ''nangka''; Tagalog, Pangasinan, Bikol and Ilocano ''langka''; Chamorro ''lanka'' or ''nanka''; Kelabit ''nakan''; Wolio ''nangke''; Ibaloi ''dangka''; and Lun Dayeh ''laka''. Note, however, that the fruit was only recently introduced to Guam via Filipino settlers when both were part of the Spanish Empire.

Bambusoideae (bamboos)

Various species of bamboo ( subfamily Bambusoideae) are found throughout Island Southeast Asia, Mainland Southeast Asia, East Asia, and South Asia. In Austronesian regions, different types of bamboos have different names, as well as the products made from them. They are used variously as building materials, fishing gear, musical instruments, knives, water and food vessels, and so on. Bamboo shoots are also a food source in Southeast Asia. A few species of bamboo were carried by Austronesian settlers as they colonized the Pacific islands. They include the ohe (''Schizostachyum glaucifolium''), the common bamboo ('' Bambusa vulgaris''), and the thorny bamboo ('' Bambusa bambos'').

Reconstructed Proto-Austronesian words that referred to bamboo include ''*qauR'', ''*kawayan'', ''*buluq'', and ''*betung''. The latter entered Proto-Malayo-Polynesian and Proto-Oceanic as ''*bitung'', with cognates including Sundanese ''awi bitung''; Fijian ''bitu''; and Tongan ''pitu''. Most terms for bamboo in Polynesia, however, originated from Proto-South-Central-Pacific ''*kofe'' (originally from Proto-Polynesian ''*kofe'', "root"). Modern cognates include Tongan and Niue ''kofe''; Tokelau, Marquesan, Tuamotuan, and Māori ''kohe''; Rarotongan ''koe''; Samoan and Tahitian ''ofe''; and Hawaiian ''ohe''. Some names have also shifted refer to bamboo-like plants; especially in islands where they were not introduced into or did not survive, like in Aotearoa.

''Benincasa hispida'' (wax gourd)

''Broussonetia papyrifera'' (paper mulberry)

Paper mulberry ('' Broussonetia papyrifera''), better known as " tapa cloth tree" in the Pacific, originates from subtropical regions in mainland Asia and is one of the best evidence for the mainstream "Out of Taiwan" hypothesis of the Austronesian expansion. Various genetic studies have traced the origins of paper mulberry populations in the Remote Pacific all the way to Taiwan via New Guinea and Sulawesi. In the Philippines, which was along the expansion path, paper mulberry are mostly descendants of modern introductions in 1935. It is presumed that ancient introductions of paper mulberry went extinct in prehistory due to its replacement with hand-woven fabrics, given that paper mulberry generally only survives under human cultivation. However, its absence in the Philippines further underlines its origins in Taiwan, and not within Island Southeast Asia. Additionally paper mulberry populations in New Guinea also show genetic inflow from another expansion out of Indochina and South China.

It is believed to be the most widely transported fiber crop in prehistory, having been transported along with the full range of the Austronesian expansion, as opposed to most of the other commensal crops in Oceania. Paper mullbery is present in almost every island or island group in Polynesia, including Rapa Nui and Aotearoa. Some populations have gone recently extinct after they stopped being cultivated, like in the Cook Islands and Mangareva, although accounts and prepared barkcloth and herbarium specimens of them exist in museum collections gathered by Europeans during the Colonial Period. They were spread by Polynesians primarily through vegetative propagation with cuttings and root shoots. They were rarely cultivated from seeds as most plants were harvested prior to flowering, when the stems reach around in diameter, as described by 18th century European accounts. It is also unknown if the feral plants reproduced sexually as the plants are dioecious and require both male and female specimens to be present in one island.

Paper mulberry is primarily used in the Pacific Islands to make barkcloth ('' tapa'' in most Polynesian languages). Barkcloth, can also be made from other members of the mulberry family (Moraceae), including ''Ficus'' (figs) and '' Artocarpus''. Barkcloth was also occasionally made from '' Pipturus'' nettles, especially in Hawaii. However the highest quality of barkcloth was from paper mulberry.

Barkcloth was mainly used for clothing among ancient Austronesians and is traditionally made using characteristic stone or wooden beaters which are among the most common artifacts found in Austronesian archaeological sites. Numerous archaeological remains of barkcloth beaters in southern China has been regarded as evidence that the pre-Taiwan Austronesian homelands were located in the region prior to the southward expansion of the Han Dynasty, particularly around the Pearl River Delta. The oldest such remains is from the Dingmo Site in Guangxi, dated to around 7,900 BP. Barkcloth remained an important source of clothing fabrics in pre-colonial Melanesia, Polynesia, and parts of Indonesia. However, it has been mostly replaced by woven fiber clothing in most of Island Southeast Asia and Micronesia.

There are numerous names for paper mulberry throughout Austronesia, the most general can be reconstructed to Proto-Central Eastern Malayo-Polynesian ''*malaw'', which also refers to the loincloth and other items of clothing made from paper mulberry bark. Its cognates including Selaru ''mal''; Asilulu ''mala ai''; Buli ''māl''; Numfor ''mār''; Tanga, Tolai, and Gedaged ''mal''; Rennellese ''mago''; Kairiru ''myal''; Lusi, Kove, Manam, Gitua, Mota, Niue, Futunan, Samoan, Tuvaluan, Nukuoro, Anuta, and Hawaiian ''malo''; and Arosi, Rarotongan, and Maōri ''maro''.

In Eastern Polynesia, terms for paper mulberry can also be reconstructed to Proto-Central Eastern-Polynesian ''*aute'', with cognates including Tahitian and Rarotongan ''aute''; Marquesan ''ute''; Hawaiian ''wauke''; Rapa and Maōri ''aute''.

In most of Polynesia, the term for barkcloth can also be reconstructed from Proto-Nuclear-Polynesian ''*taba'', meaning "bark", with cognates including Wayan ''taba''; Tongan, Samoan, Mangareva, and Rarotongan ''tapa''; and Hawaiian ''kapa''. Other terms widely used for barkcloth and paper mulberry are derived from the Proto-Polynesian reconstructed word ''*siapo'', with cognates including Niue, Tongan, and Marquesan ''hiapo''; and Samoan and East Futunan ''siapo''. The term for barkcloth beater, however, can be reconstructed more extensively back to Proto-Malayo-Polynesian ''*ike'', with cognates including Uma ''ike''; Sa'a ''iki''; Bauan, Tongan, and East Futunan ''ike''; and Samoan and Hawaiian ''ie''.

''Calophyllum inophyllum'' (mastwood)

Mastwood (''Calophyllum inophyllum'') is a widespread timber tree native to tropical Asia. It is notable for its ability to grow to massive sizes in sandy or rocky beaches of island and coastal habitats, as well as its habit of sending out arching large trunks over the water where its seeds are dispersed via the currents. Due to these characters, mastwood are of particular importance to traditional shipbuilding of the larger Austronesian outrigger ships and were carried with them as they migrated to Oceania and Madagascar.

Other species of the genus ''Calophyllum'' were also used similarly, like ''Calophyllum soulattri'', ''Calophyllum peekelii'', and ''Calophyllum goniocarpum''. The wood grain of the members of the genus are characteristically interlocked, which make them harder to work with but also makes them stronger as well as being more suitable for carving intricate shapes. They were comparable in importance to how oaks were in European shipbuilding and timber industries. In many parts of Polynesia, mastwood groves planted in ''marae'' were considered sacred and abodes of spirits. Mastwood were also carved into religious objects like '' tiki''. They are also commonly mentioned in the chants and folklore of Polynesia.

Various parts of the mastwood were integral to the manufacture of outrigger canoes. The large curving limbs were commonly carved into the dugout canoes that formed the keel of the Austronesian outriggers ships. The strakes, which are attached to the keel by the uniquely Austronesian technique of "sewing" them with a combination of dowels and lashed lugs instead of nails, can also be made from mastwood, but it is more commonly made from other "softer" timber species like '' Artocarpus''. Other pieces became masts, outrigger floats, and outrigger spars. Smaller curving limbs can also be carved into the ribs of the boat.

Aside from shipbuilding, tamanu oil extracted from the fruit kernels were important in Polynesian culture. The oils, as well as poultices made from leaves and flowers, are also commonly used for traditional medicine. The leaves contain compounds that are poisonous to fish and can be used as fish poison.

The reconstructed Proto-Austronesian word for mastwood is ''*bitaquR'', with modern cognates including Ilocano ''bittáug''; Ifugao ''bitául''; Bikol, Cebuano, Maranao, Mansaka and Manobo ''bitáog'' or ''bitaug''; Nias ''bito''; Palauan ''btáəs''; Wetan ''witora''; and Asilulu ''hataul''. The Western Malayo-Polynesian words for mastwood is derived from the doublet Proto-Austronesian ''*bintaŋuR'', with cognates including Iban, Malay and Toba Batak ''bintangur'' or ''bentangur''; Tontemboan ''wintangor''; and Malagasy ''vintáno''. In Proto-Oceanic, the reconstructed word is ''pitaquR'', with cognates including Nauna ''pitɨ''; Loniu ''pitow''; Nali ''pirow''; Seimat ''hita''; Aua ''piaw''; Pohnpeian ''isou''; Rotuman ''hefau''; Fijian ''vetau'', Tongan ''fetau''; Niue, Samoan, and Tuvaluan ''fetau''; Nukuoro ''hedau''; and Rennellese ''hetau''. In most of these languages, the name specifically refers to ''C. inophyllum'', although in Ifugao, Maranao, Nias, Wetan, and Fijian, the name has become more generalized to large timber trees.

Another set of cognates for ''C. inophyllum'' in Proto-Oceanic can be reconstructed as ''*tamanu''. Its difference from ''*pitaquR'' is unclear, but given the distinction between the terms in the Mussau reflex, ''*tamanu'' probably originally referred to specimens of the tree that grow in island interiors and not on the coastlines. Modern cognates include Mussau, Tongan, Niue, Samoan, and Rarotongan ''tamanu''; Fijian ''damanu''; and Hawaiian ''kamani''.

''Cananga odorata'' (ylang-ylang)

'' Cananga odorata'', with its large, aromatic flowers, is used for ornamentation. It is not known whether it is native to Polynesia and Melanesia or introduced.

''Citrus''

Numerous species of Citrus are native to Island Southeast Asia, Mainland Southeast Asia, East Asia, South Asia and Near Oceania. The Austronesians cultivated and gathered a variety of citrus for food, medicine and washing with the thorns being used as piercing implements for tattooing. '' Citrus hystrix'', '' Citrus macroptera'', and '' Citrus maxima'' were also among the canoe plants carried by Austronesian voyagers eastwards into Micronesia and Polynesia.

''Cocos nucifera'' (coconut)

The region between Southwest Asia and Melanesia is the center of origin for coconuts ('' Cocos nucifera''), where it shows greatest genetic diversity. A study in 2011 identified two highly genetically differentiated subpopulations of coconuts, one originating from Island Southeast Asia (the Pacific group) and the other from the southern margins of the Indian subcontinent (the Indo-Atlantic group). The Pacific group is the only one to display clear genetic and phenotypic indications that they were domesticated; including dwarf habit, self-pollination, and the round "''niu vai''" fruit morphology with larger endosperm-to-husk ratios. The distribution of the Pacific coconuts correspond to the regions settled by Austronesian voyagers indicating that its spread was largely the result of human introductions.

It is most strikingly displayed in Madagascar, an island settled by Austronesian sailors at around 2,000 to 1,500 BP. The coconut populations in the island show genetic admixture between the two subpopulations indicating that Pacific coconuts were brought by the Austronesian settlers that later interbred with the local Indo-Atlantic coconuts.

Most words for "coconut" in Austronesian languages are derived from proto-Malayo-Polynesian ''* niuʀ''. Modern cognates include Tagalog ''niyog''; Chamorro ''niyok''; Malay ''nyiur'' or ''nyior''; Tetum ''nuu''; Drehu ''nu''; Gilbertese ''nii''; Hawaiian, Samoan, Tongan, Fijian, and Rapa Nui ''niu''; and Malagasy '' nio''.

Genetic studies of coconuts have also confirmed pre-Columbian populations of coconuts in Panama in South America. However, it is not native and display a genetic bottleneck resulting from a founder effect. A study in 2008 showed that the coconuts in the Americas are genetically closest related to coconuts in the Philippines, and not to any other nearby coconut populations (including Polynesia). Such an origin indicates that the coconuts were not introduced naturally, such as by sea currents. The researchers concluded that it was brought by early Austronesian sailors to the Americas from at least 2,250 BP, and may be proof of pre-Columbian contact between Austronesian cultures and South American cultures, albeit in the opposite direction than what early hypotheses like Heyerdahl's had proposed. It is further strengthened by other similar botanical evidence of contact, like the pre-colonial presence of sweet potato in Oceanian cultures. During the colonial era, Pacific coconuts were further introduced to Mexico from the Spanish East Indies via the Manila galleons.

In contrast to the Pacific coconuts, Indo-Atlantic coconuts were largely spread by Arab and Persian traders into the East African coast. Indo-Atlantic coconuts were also introduced into the Atlantic Ocean by Portuguese ships from their colonies in coastal India and Sri Lanka; first being introduced to coastal West Africa, then onwards into the Caribbean and the east coast of Brazil. All of these introductions are within the last few centuries, relatively recent in comparison to the spread of Pacific coconuts.

''Coix lacryma-jobi'' (Job's tears)

''Colocasia esculenta'' (taro)

The taro (''Colocasia esculenta''), sometimes referred to as the "true taro", is one of the most ancient cultivated crops and pre-dated the Austronesian expansion. Taro is found widely in tropical and subtropical regions of South Asia, East Asia, Southeast Asia, Papua New Guinea, and northern Australia and is highly polymorphic, making taxonomy and distinction between wild and cultivated types difficult. It is believed that they were domesticated independently multiple times, with authors giving possible locations as New Guinea, Mainland Southeast Asia, and northeastern India, based largely on the assumed native range of the wild plants. However, more recent studies have pointed out that wild taro may have a much larger native distribution than previously believed, and wild breeding types may also likely be indigenous to other parts of Island Southeast Asia.


Archaeological traces of taro exploitation have been recovered from numerous sites pre-dating the Austronesian expansion, though whether these were cultivated or wild types can not be ascertained. They include the Niah Caves of Borneo, dating to <40,000 BP; Ille Cave of Palawan, dated to at least c. 11,000 BP; Kuk Swamp of New Guinea, dated to 10,200 to 9,910 cal BP; and Kilu Cave in the Solomon Islands dated to around c. 28,000 to 20,000 BP. In the case of Kuk Swamp, there is evidence of formalized agriculture emerging by about c. 10,000 BP, with evidence of cultivated plots, though which plant was cultivated remains unknown.

Regardless, taro were definitely among the cultivated plants of Austronesians as well as preceding populations in Island Southeast Asia. However, their importance in Island Southeast Asia had largely been replaced by rice, although they are still planted at the margins of rice paddies in some communities. They remained a staple in the islands of Melanesia and Polynesia where rice wasn't introduced. They are one of the four species of aroids (taros) cultivated by Austronesians primarily as a source of starchy corms, the others being ''Alocasia macrorrhizos'', '' Amorphophallus paeoniifolius'', and '' Cyrtosperma merkusii''. They are the most important and the most preferred among the four, because they were less likely to contain the irritating raphides present in the other plants.

Taro is also identified as one of the staples of Micronesia, from archaeological evidence dating back to the pre-colonial Latte Period (c. 900 – 1521 AD), indicating that it was also carried by Micronesians when they colonized the islands. Due to the unsuitability of the low-lying atoll islands of most of Micronesia, Micronesians innovated by digging pits that could then be filled up with compost suitable for taro cultivation. Taro pollen and starch residue have also been identified in earlier Lapita sites, dated to around c. 3,050 – 2,500 cal BP.

There are numerous terms for taro in the Austronesian languages, both specific and generalized. The reconstructed Proto-Austronesian term for taro is ''*cali'', with cognates in Formosan languages including Seediq ''sali'', Thao ''lhari''; Bunun ''tai''; and Amis ''tali''.

It became ''* taləs'' in Proto-Malayo-Polynesian, which in turn became ''*talos'' or ''*talo'' in Proto-Oceanic. Modern cognates include Hanunó'o ''tálus''; Aborlan Tagbanwa ''talis''; Palawan Batak ''täläs''; Nias ''talõ''; Malay ''talas''; Minangkabau ''taleh''; Rejang and Sundanese ''taleus''; Javanese ''tales''; Palauan ''dáit''; Rotinese ''tale''; and Tetun ''talas''. In Polynesian languages, the cognates include Motu, Marovo, Tongan, Samoan, Niue, Futunan, Tuvaluan ''talo''; Kwaio, Lau (Malaita), and Toqabaqita ''alo''; 'Āre'āre, Arosi, and Bauro ''aro''; Nakanamanga ''na-tale''; Sye ''tal'' or ''nal''; Fijian and Nukuoro ''dalo''; Rennellese ''tago''; Anuta, Rarotongan, and Māori ''taro''; and Hawaiian ''kalo''. The English name for the plant is itself derived from the Polynesian names. A red variety of taro also has names derived from reconstructed Proto-Polynesian ''*pongi'', with cognates including Niue ''pongi''; Marquesan ''poki''; Hawaiian ''poni''; and Māori ''pongi''.

In Proto-Western-Malayo-Polynesian, another reconstructed term is ''*kaladi'', with cognates including Agutaynen, Sabah Bisaya, Iban, Tae', and Wolio ''kaladi''; Balinese and Malay ''keladi''; and Mongondow ''koladi''.

''Cordia subcordata'' (beach cordia)

The beach cordia ('' Cordia subcordata'') is an important timber tree with light, finely textured, and somewhat soft wood ideal for carving. It has no taste and thus was most commonly used for carving utensils, cups, bowls, and other containers; as well as ornamental carvings and musical instruments throughout Austronesia. The wood is flammable and is commonly used in New Guinea as firewood. In some cultures, the wood may also be used to build paddles and the keels of the boats. The seeds can also be eaten, though only as famine food. Other parts can also be used for traditional medicine and for the extraction of dyes. Like ''Calophyllum inophyllum'', beach cordia were commonly planted in ''marae''. They have cultural and religious significance in some cultures like in Kiribati and the Karimunjawa Islands of Indonesia. In Hawaii, it was traditional to plant beach cordia around houses and use their bright orange flowers as leis.

Beach cordia, like most trees favored by Austronesians, grow well in sandy, clay, and rocky soil and are a common component in coastal forests and mangrove forests. Beach cordia was once thought to be an introduced species, but it is now known to be indigenous to most of the islands and coastlines of the Indo-Pacific, propagated naturally by their buoyant seeds. Nevertheless, they were still deliberately introduced in some islands, with artificial introductions usually found growing with other common trees cultivated by Austronesians. Especially in the atolls of Micronesia.

Terms for beach cordia is reconstructed to Proto-Malayo-Polynesian ''*kanawa'', with cognates including Iban ''kenawa''; Makasarese ''kanawa''; Palauan ''kəláu''; Gilbertese ''kanawa''; Tokelau ''kanava''; and Nukuoro ''ganava''.

Another set of cognates can be reconstructed to Proto-Oceanic ''*toRu'', with cognates including Nehan ''to-tor''; Petats ''to-tol''; Fijian, Tongan, and Rarotongan ''tou''; and Hawaiian ''kou''.

An older reconstructed term is Proto-Austronesian ''*qaNuNaŋ'', however it is not specific to beach cordia and can refer to other members of the genus with sticky fruits, especially the glue berry ('' Cordia dichotoma'') and the lasura ('' Cordia myxa''). It also did not reach the Oceanic languages. Cognates include Tsou ''həhngə''; Isneg ''anúnang''; Hanunó'o and Cebuano ''anúnang''; Maranao ''nonang''; Manobo ''enunang''; Mansaka ''anonang''; Malay, Minangkabau, Sasak, Manggarai, and Rembong ''nunang''; and Mongondow ''onunang''.

''Cordyline fruticosa'' (ti)

Ti ('' Cordyline fruticosa'') is a palm-like plant growing up to tall with an attractive fan-like and spirally arranged cluster of broadly elongated leaves at the tip of the slender trunk. It has numerous color variations, ranging from plants with red leaves to green, yellow, and variegated cultivars. Its original native distribution is unknown, but it is believed to be native to the region from Bangladesh, to Mainland Southeast Asia, South China, Taiwan, Island Southeast Asia, New Guinea, and Northern Australia. It has the highest morphological diversity in New Guinea and is believed to have been extensively cultivated there. It is commonly misidentified as a " Dracaena", along with members of the genus ''Cordyline'', due to past classification systems.

It was carried throughout Oceania by Austronesians, reaching as far as Hawaii, New Zealand, and Easter Island at their furthest extent. A particularly important type of ti in Polynesia is a large green-leafed cultivar grown for their enlarged edible rhizomes. Unlike the ti populations in Southeast Asia and Near Oceania, this cultivar is almost entirely sterile in the further islands of eastern Polynesia. It can only be propagated by cuttings from the stalks or the rhizomes. It is speculated that this was the result of deliberate artificial selection, probably because they produce larger and less fibrous rhizomes more suitable for use as food.

Ti has many uses but it is most notable as one of the most important plants related to the indigenous animist religions of Austronesians, along with fig trees (''Ficus'' spp.). It is very widely regarded as having mystical or spiritual powers in various Austronesian (as well as Papuan) cultures. Among a lot of ethnic groups in Austronesia it is regarded as sacred. Common features include the belief that they can hold souls and thus are useful in healing " soul loss" illnesses and in exorcising against malevolent spirits, their use in ritual attire and ornamentation, and their use as boundary markers. Red and green cultivars also commonly represented dualistic aspects of culture and religion and are used differently in rituals. Red ti plants commonly symbolize blood, war, and the ties between the living and the dead; while green ti plants commonly symbolize peace and healing. They are also widely used for traditional medicine, dye, and ornamentation throughout Austronesia and New Guinea. Their ritual uses in Island Southeast Asia have largely been obscured by the introduction of Hinduism, Buddhism, Islamic, and Christian religions, but they still persist in certain areas or are coopted for the rituals of the new religions.

In Polynesia, the leaves of the green-leafed form are used to wrap food, line earth ovens and fermentation pits of breadfruit, and their rhizomes harvested and processed into a sweet molasses-like pulp eaten like candy or used to produce a honey-like liquid used in various sweet treats. In Hawaii, the roots are also mixed with water and fermented into an alcoholic beverage known as ''okolehao''. Fibers extracted from leaves are also used in cordage and in making bird traps. The consumption of ti as food, regarded as a sacred plant and thus was originally taboo, is believed to have been a daring innovation of Polynesian cultures as a response to famine conditions. The lifting of the taboo is believed to be tied to the development of the firewalking ritual.

In Philippine anitism, ti were commonly used by '' babaylan'' (female shamans) when conducting mediumship or healing rituals. A common belief in Filipino cultures is that the plant has the innate ability to host spirits. Among the Ifugao people of Northern Luzon, it is planted around terraces and communities to drive away evil spirits as well as mark boundaries of cultivated fields. The red leaves are believed to be attractive to spirits and is worn during important rituals as part of the headdresses and tucked into armbands. In the past, it was also worn during ceremonial dances called ''bangibang'', which was performed by both men and women for warriors who died in battle or through violent means. They are also used to decorate ritual objects. Among the Palaw'an people, it is planted in burial grounds to prevent the dead from becoming malevolent spirits.

In Indonesia, red ti are used similarly as in the Philippines. Among the Dayak, Sundanese, Kayan, Kenyah, Berawan, Iban and Mongondow people, red ti are used as wards against evil spirits and as boundary markers. They are also used in rituals like in healing and funerals and are very commonly planted in sacred groves and around shrines. The Dayak also extract a natural green dye from ti. During healing rituals of the Mentawai people, the life-giving spirit are enticed with songs and offerings to enter ti stems which are then reconciled with the sick person. Among the Sasak people, green ti leaves are used as part of the offerings to spirits by the ''belian'' shamans. Among the Baduy people, green ti represent the body, while red ti represent the soul. Both are used in rice planting rituals. They are also planted on burial grounds. Among the Balinese and Karo people, ti plants are planted near village or family shrines in a sacred grove. Among the Toraja people, red ti plants are used in rituals and as decorations of ritual objects. They are believed to occur in both the material and the spirit worlds (a common belief in Austronesian animism). In the spirit world, they exist as fins and tails of spirits. In the material world, they are most useful as guides used to attract the attentions of spirits. The red leaves are also symbolic of blood and thus of life and vitality. Among the Ngaju people, ti plants were symbolic of the sacred groves of ancestors. They were also important in ritual promises dedicated to high gods. They were regarded as symbolic of the masculine "Tree of Life", in a dichotomy against ''Ficus'' species which symbolize the feminine "Tree of the Dead".

In New Guinea, ti are commonly planted to indicate land ownership for cultivation and are also planted around ceremonial men's houses. They are also used in various rituals and are commonly associated with blood and warfare. Among the Tsembaga Maring people, they are believed to house "red spirits" (spirits of men who died in battle). Prior to a highly ritualized (but lethal) warfare over land ownership, they are uprooted and pigs are sacrificed to the spirits. After the hostilities, they are re-planted in the new land boundaries depending on the outcome of the fight. The men involved ritually place their souls into the plants. The ritual warfare have been suppressed by the Papua New Guinea government, but parts of the rituals still survive. Among the Ankave people, red ti is part of their creation myth, believed as having arisen from the site of the first murder. Among the Mendi and Sulka people they are made into dyes used as body paint, and their leaves are used for body adornments and purification rituals. Among the Nikgini people, the leaves have magical abilities to bring good luck and are used in divination and in decorating ritual objects. Among the Kapauku people, ti plants are regarded as magical plants and are believed to be spiritual beings themselves. Unlike other magical plants which are controlled by other spirits, ti plants had their own spirits and are powerful enough to command other spiritual beings. Red plants are used in white magic rituals, while green plants are used in black magic rituals. They are also commonly used in protection and warding rituals. Among the Baktaman people, red plants are used for initiation rites, while green plants are used for healing. The Ok-speaking peoples also regard ti plants as their collective totem.

In Island Melanesia, ti are regarded as sacred by various Austronesian-speaking peoples and are used in rituals for protection, divination, and fertility. Among the Kwaio people, red ti are associated with feuding and vengeance, while green ti are associated with ancestor spirits, markers of sacred groves, and wards against evil. The Kwaio cultivate these varieties around their communities. Among the Maenge people of New Britain, ti leaves are worn as everyday skirts by women. The color and size of leaves can vary by personal preference and fashion. New cultivars with different colors are traded regularly and strands of ti are grown near the village. Red leaves can only worn by women past puberty. Ti is also the most important plant in magic and healing rituals of the Maenge. Some ti cultivars are associated with supernatural spirits and have names and folklore around them. In Vanuatu, ''Cordyline'' leaves, known locally by the Bislama name ''nanggaria'', are worn tucked into a belt in traditional dances like Māuluulu, with different varieties having particular symbolic meanings. Cordylines are often planted outside '' nakamal'' buildings. In Fiji, red ti leaves are used as skirts for dancers and are used in rituals dedicated to the spirits of the dead. They are also planted around ceremonial buildings used for initiation rituals.

In Micronesia, ti leaves are buried under newly built houses in Pohnpei to ward off malign sorcery. In instances of an unknown death, shamans in Micronesia communicate with the dead spirit through ti plants, naming various causes of death until the plant trembles. There is also archaeological evidence that the rhizomes of the plants were eaten in the past in Guam prior to the Latte Period.

In Polynesia, green ti were cultivated widely for food and religious purposes. They are commonly planted around homes, in sacred places (including ''marae'' and ''heiau''), and in grave sites. The leaves are also carried as a charm when traveling and the leaves are used in rituals that communicate with the species. Like in Southeast Asia, they are widely believed to protect against evil spirits and bad luck; as well as having the ability to host spirits of dead people, as well as nature spirits.

In ancient Hawaii the plant was thought to have great spiritual power; only '' kahuna'' (shamans) and '' alii'' (chiefs) were able to wear leaves around their necks during certain ritual activities. Ti was sacred to the god of fertility and agriculture Lono, and the goddess of the forest and the hula dance, Laka. Ti leaves were also used to make lei, and to outline borders between properties. It was also planted at the corners of the home to keep evil spirits away. To this day some Hawaiians plant ti near their houses to bring good luck. The leaves are also used for lava sledding. A number of leaves are lashed together and people ride down hills on them. The leaves were also used to make items of clothing including skirts worn in dance performances. The Hawaiian hula skirt is a dense skirt with an opaque layer of at least fifty green leaves and the bottom (top of the leaves) shaved flat. The Tongan dance dress, the ''sisi'', is an apron of about 20 leaves, worn over a '' tupenu'', and decorated with some yellow or red leaves.

In Aotearoa, certain place names are derived from the use and folklore of ti, like Puketī Forest and Temuka. The ti plants in Kaingaroa are known as ''nga tī whakāwe o Kaingaroa'' ("the phantom trees of Kaingaroa"), based on the legend of two women who were turned into ti plants and seemingly follow people traveling through the area.

The reconstructed Proto-Malayo-Polynesian word for ti is ''*siRi''. Cognates include Malagasy ''síly''; Palauan ''sis''; Ere and Kuruti ''siy''; Araki ''jihi''; Arosi ''diri''; Chuukese ''tii-n''; Wuvulu ''si'' or ''ti''; Tongan ''sī''; Samoan, Tahitian, and Māori ''tī''; and Hawaiian ''kī''. The names in some languages have also been applied to the garden crotons ('' Codiaeum variegatum''), which similarly have red or yellow leaves. The cognates of Proto-Western-Malayo-Polynesian ''*sabaqaŋ'', similarly, have been applied to both garden crotons and ti plants.

In the Philippines, they are also known by names derived from the Proto-Austronesian ''*kilala'', "to know", due to its use in divination rituals. Cognates derived from that usage include Tagalog ''sagilala''; and Visayan and Bikol ''kilála'' or ''kilaa''. In New Zealand, the terms for ti were also transferred to the native and closely related cabbage tree (''Cordyline australis''), as ''tī kōuka''.

''Cucumis melo'' (melon)

''Cyrtosperma merkusii'' (giant swamp taro)

''Dioscorea'' (yams)

Yams (''Dioscorea'' spp.) is a very large group of plants native throughout tropical and warm temperate regions of the world. Various species of yams were domesticated and cultivated independently within Island Southeast Asia and New Guinea for their starchy tubers, including the ube (''Dioscorea alata''), round yam ('' Dioscorea bulbifera''), intoxicating yam ('' Dioscorea hispida''), lesser yam ('' Dioscorea esculenta''), Pacific yam ('' Dioscorea nummularia''), fiveleaf yam ('' Dioscorea pentaphylla''), and pencil yam ('' Dioscorea transversa''). Among these, ''D. alata'' and ''D. esculenta'' were the only ones regularly cultivated and eaten, while the rest were usually considered as famine food due to their higher levels of the toxin dioscorine which requires that they be prepared correctly before consumption.

''D. alata'' and ''D. esculenta'' were the most suitable for long transport in Austronesian ships and were carried through all or most of the range of the Austronesian expansion. ''D. alata'' in particular, were introduced into the Pacific Islands and New Zealand. They were also carried by Austronesian voyagers into Madagascar and the Comoros.

''Dioscorea alata'' (ube)

The ube (''Dioscorea alata''), also known as the greater yam or water yam, is one of the most important staple crop in Austronesian cultures. It is the main species cultivated among ''Dioscorea'', largely because of its much larger tubers and its ease of processing. Its center of origin is unknown, but archaeological evidence suggests that it was exploited in Island Southeast Asia and New Guinea before the Austronesian expansion. Ube is believed to be a true cultigen, only known from its cultivated forms. It is a polyploid and is sterile, and thus can not cross bodies of water. This restricts its introduction into islands purely by human agency, making them a good indicator of human movement. Some authors have proposed an origin in Mainland Southeast Asia without evidence, but it shows the greatest phenotypic variability in the Philippines and New Guinea.

Based on archaeological evidence of early farming plots and plant remains in the Kuk Swamp site, authors have suggested that it was first domesticated in the highlands of New Guinea from around 10,000 BP and spread into Island Southeast Asia via the Lapita culture at around c. 4,000 BP, along with ''D. nummularia'' and ''D. bulbifera''. In turn, ''D. esculenta'' is believed to have been introduced by the Lapita culture into New Guinea. There is also evidence of an agricultural revolution during this period brought by innovations from contact with Austronesians, including the development of wet cultivation.

However, much older remains identified as being probably ''D. alata'' have also been recovered from the Niah Caves of Borneo (Late Pleistocene, <40,000 BP) and the Ille Cave of Palawan (c. 11,000 BP), along with remains of the toxic ubi gadong (''D. hispida'') which requires processing before it can be edible. Although it doesn't prove cultivation, it does show that humans already had the knowledge to exploit starchy plants and that ''D. alata'' were native to Island Southeast Asia. Furthermore, it opens the question on whether ''D. alata'' is a true species or cultivated much older than believed.

Ube remains an important crop in Southeast Asia. Particularly in the Philippines where the vividly purple variety is widely used in various traditional and modern desserts. It also remains important in Melanesia, where it is also grown for ceremonial purposes tied to the size of the tubers at harvest time. Its importance in eastern Polynesia and New Zealand, however, has waned after the introduction of other crops, most notably the sweet potato.

The reconstructed Proto-Austronesian word for ube is ''*qubi'', which became Proto-Malayo-Polynesian ''*qubi'', and Proto-Oceanic ''*qupi''. It has some of the most recognizable and widespread reflexes in Austronesian languages. Modern cognates include Yami ''uvi''; Itbayaten ''ovi''; Bontoc and Hanunó'o ''úbi''; Ilocano, Tagalog, Cebuano, Pangasinan, Aklanon, Itneg, and Itawis ''úbi'' or ''úbe''; Kalamian Tagbanwa ''kubi''; Maranao ''obi''; Tiruray ''ubi''; Manobo ''uvi''; Kenyah, Malay, Iban, Balinese, Sasak, Mongondow, and Toba Batak ''ubi''; Javanese ''uwi''; Kelabit ''ubih''; Melanau ''ubey''; Ngaju Dayak ''owi''; Malagasy ''óvy''; Tsat ''phai''; Jarai ''hebey''; Moken ''koboi''; Sundanese ''huwi''; Tontemboan, Bimanese, and Manggarai ''uwi''; Ngadha ''uvi''; Rotinese ''ufi''; Erai ''uhi''; Selaru ''uh'' or ''uhi-re''; Watubela ''kuwi''; Buruese ''ubi-t''; Koiwai ''uf''; Buli ''up''; and Waropen ''uwi''.

Among Oceanic languages, cognates include Nauna ''kuh''; Penchal ''kup''; Leipon ''uh''; Tolai ''up''; Lakalai ''la-huvi''; Gapapaiwa and Kilivila ''kuvi''; Papapana ''na-uvi''; Simbo, Bugotu, and Nggela, and Fijian ''uvi''; Kwaio, Niue, and Samoan ''ufi''; Sa'a, Arosi, Tuamotuan, Hawaiian and Rapa Nui ''uhi''; Marquesan ''puauhi''; Haununu ''a-uhi''; Avava 'o-ovi''; Rennellese ''uhi''; Tongan ''ufi''; Anuta ''upi''; Rarotongan ''ui''; and Māori ''uwhi'' or ''uhi''.

In some ethnic groups, the word has been generalized or shifted to mean other types of yams, as well as the sweet potato and cassava. Other words for ube are also derived from the ancestral names of other species of yam.

''Dioscorea bulbifera'' (air yam)

The air yam ('' Dioscorea bulbifera''), also known as the bitter yam, is one of the lesser cultivated species of yam. It is usually only eaten as famine food in Island Southeast Asia, Melanesia, and Polynesia, because of the toxicity of some wild or feral plants when not cooked correctly. However it is one of only three yams that were carried by Austronesians into Remote Oceania, the others being ''D. alata'' and ''D. nummularia''. The part of the plant harvested are the aerial tubers, as it does not usually produce large underground tubers.

It can be reconstructed to Proto-Oceanic as ''*pwatika'' or ''*pʷatik'', with cognates including Lou ''puet''; Lamusong ''patik''; Boanaki ''posika''; and Kwara'ae ''fasia''. However, in Lamusong its meaning has shifted to the lesser yam, while in Boanaki, the meaning has shifted to a more generalized term for yams. It can also be reconstructed to the more generalized Proto-Oceanic ''*balai'', meaning "wild yam", which became Proto-Micronesian ''*palai'', with cognates including Rotuman ''parai''; Tongan, Niue, and Samoan ''palai''; and Rennellese ''pagai''.

''Dioscorea esculenta'' (lesser yam)

The lesser yam ('' Dioscorea esculenta'') is the second most important yam crop among Austronesians. Like ''D. alata'', it requires minimal processing, unlike the other more bitter yam species. However, it has smaller tubers than ''D. alata'' and is usually spiny. Like ''D. alata'' it was introduced to Madagascar and the Comoros by Austronesians, where it spread to the East African coast. They are also a dominant crop in Near Oceania, However, it did not reach to the furthest islands in Polynesia, being absent in Hawaii and New Zealand.

Starch grains identified to be from the lesser yam have been recovered from archaeological sites of the Lapita culture in Viti Levu, Fiji, dated to around 3,050 to 2,500 cal BP. Traces of ''D. esculenta'' (along with ''D. alata'', ''D. bulbifera'', ''D. nummularia'' and ''D. pentaphylla'') yams have also been identified from the Mé Auré Cave site in Moindou, New Caledonia, dated to around 2,700 to 1,800 BP. Remains of ''D. esculenta'' have also been recovered from archaeological sites in Guam, dated to around 1031 CE. ''D. esculenta'' is believed to have been introduced by the Lapita culture into New Guinea at around 4,000 BP, along with agricultural innovations like wet cultivation as well as swidden farming. In archaeological sites in New Guinea, it is associated with the appearance of high-density populations in the coastal areas.

Terms for lesser yam in Austronesian languages are mostly affixed or two-word forms derived from the ''*qubi'' root for ''D. alata'', like Samoan ''ufi lei'', ''Sundanese'' ''ubi aung'', Malay ''ubi torak'', and Javanese ''ubi gemblii''. A term for lesser yam can be reconstructed in Proto-Philippine as ''*tugiq'', but its cognates are limited to the island of Luzon, including Ivatan ''togi''; Ilocano and Kankana-ey ''tugí''; Bontoc and Ifugao ''tugi''; and Tagalog ''tugi''. No Proto-Oceanic term can be reconstructed for the lesser yam because it is absent in Remote Oceania. However, it can be reconstructed in Proto-Western-Oceanic as ''*kamisa'', ''*qamisa'', or ''*mamisa''.

''Dioscorea hispida'' (intoxicating yam)

The intoxicating yam ('' Dioscorea hispida''), is native to tropical Asia and New Guinea. It is only cultivated minimally in parts of Java. Elsewhere it is harvested from the wild. Like ''D. bulbifera'' it has toxic tubers that need to be prepared correctly before they can be eaten, and thus were only suitable for famine food. However, it is one of the ''Dioscorea'' species identified from the Niah Caves archaeological site dating to <40,000 BP. Its names can be reconstructed to Proto-Western-Malayo-Polynesian ''*gaduŋ''. Its modern cognates in most Western Malayo-Polynesian languages is ''gadung'' or ''gadong'' (also ''ubi gadung'' or ''ubi gadong''). The names are also applied to the similarly toxic introduced cassava.

''Ficus'' (fig trees)

Ficus is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes of the family ''Moraceae'', which are collectively known as fig trees or figs. These plants are native to the tropics, with some species extending into the semi-warm temperate zone. Despite not being a genus exclusive to the Austronesian regions, several species such as ''ficus dammaropsis'', ''ficus fistulosa'', ''ficus hispida'', ''ficus nota'', ''ficus pseudopalma' ', ''ficus septica'', ''ficus variegata'', ''ficus aspera'', ''ficus fraseri'', ''ficus tinctoria'', ''ficus ulmifolia'', ''ficus wassa'' , ''ficus mutabilis'', ''ficus deltoidea'', ''ficus nota'' and ''ficus pseudopalma'' are endemic to these regions, and played an important role in Austronesian cultures.

''Ficus aspera''

''Ficus aspera'', also known as mosaic fig, is a plant native to Vanuatu, in the South Pacific region. The fruits of this plant are cauliflowerous (fruits that form from their main stems or woody trunks instead of new shoots). The mosaic fig is used as an ornamental plant.

''Ficus dammaropsis''

''Ficus dammaropsis'', known as ''kapiak'' in Tok pisin, is a tropical fig with huge 60 cm pleated leaves native to the highlands and highland fringe of New Guinea . Its fruit is edible, but it is rarely eaten except as an emergency food. When consumed, the young leaves are pickled or boiled and eaten as a verdera with pork.

''Ficus fraseri''

''Ficus fraseru'', also known as white sandpaper fig and bright sandpaper fig is one of several species of figs known as paper figs' sandpaper . This fig is native to New South Wales, Queensland, and Northern New Caledonia and Vanuatu. This fig grows as a bush or as a tree, with a height that varies between 6 and 15 meters. Its leaves are 6 to 14 cm long and 2.5 to 6.5 cm wide on petioles 1 to 2 cm long. The rounded figs are 1 to 1.5 cm long and start out yellow, maturing to orange-red between May and February in the species' native range. These are edible but tasteless. Although rarely seen in cultivation, it is a fast growing ornamental species. It can be easily propagated from seeds.

''Ficus nota''

''Ficus nota'', is a species of flowering plant known as tibig, found near water at low altitudes. The tibig is native to the Philippines. They are also found in parts of northern Borneo, in Malaysia. The tree can grow up to 9 meters high.

The fruits are also edible for humans, although they are quite tasteless. They are usually eaten with sugar and cream in the Philippines. The raw leaves are also eaten as a vegetable.

''Ficus pseudopalma''

''Ficus pseudopalma'', is a species of fig commonly known as Philippine fig, Philippine fig, dracaena fig or palm leaf fig' . This is an endemic species of Philippines, especially the island of Luzon.Starr, F., et al. (2003)
''Ficus pseudopalma'' Fact Sheet.
Hawaiian Ecosystems at Risk.

This is a bush that grows erect with a bare, branchless stem topped with a clump of leaves that give it the appearance of a palm tree (hence the term ''pseudopalma'' in its name, meaning "false palm"). The fruit is a dark green fig that grows in pairs, each fruit just over an inch long.

In Luzon, this plant is found in grassland and forest habitats, where it is considered common. The shoots of this plant are consumed as a type of vegetable, and there are several traditional uses; among these is its use as a remedy for kidney stones, which is obtained from the leaves. In the Bicol region, the plant is known as ''Lubi-lubi'', and the ojas are cooked in coconut milk. This shrub has also been used as a landscaping plant in Hawaii, but it never escaped cultivation or became established in the wild, because the wasp species that pollinates it never reached the islands.Villegas, KL and FA Pollisco Jr. (2008)

''Ficus tinctoria''

''Ficus tinctoria'', also known as coloring fig or hunchback fig, is a tree belonging to one of the species known as strangler figs. This is found in Malaysia, northern Australia and the islands of the South Pacific.

Palms are favorable host species. The root systems of the coloring fig can join to be self-supporting, but the epiphyte usually drops if the host tree dies or rots.
The small rust-brown fruit of the dye fig is the source of a red dye used in traditional fabric making in parts of Oceania and Indonesia. The fruit is also edible and an important food source in the low-lying atolls of Micronesia and Polynesia.

''Ficus variegata''

''Ficus variegata'', is a species of tropical fig found in various parts of Asia, Pacific islands and southeastern Australia. There are several names for this species, such as common red-stemmed fig, green-fruited fig and variegated fig.

''Ipomoea batatas'' (sweet potato)

''Lageneria siceraria'' (bottle gourd)

''Morinda citrifolia'' (noni)

Noni ('' Morinda citrifolia'') is native to Southeast Asia extending to New Guinea and northern Australia. It grows readily in beach and rocky environments. It has been introduced widely into the Pacific. All parts of the plant were used by Austronesians for traditional medicine and timber, but its most common traditional use is for the extraction of red or yellow dyes. The odor of the plant and the fruit was also traditionally believed to repel evil spirits. The fruit is also edible, but is usually only eaten as famine food.

There are several terms for noni that can be reconstructed. The most widespread is Proto-Central-Eastern Malayo-Polynesian ''*ñəñu''. Cognates include Kapampangan ''lino''; Tagalog and Bikol ''níno''; Cebuano ''ninú''; Gedaged ''nanom'' or ''nonom''; Takia ''nom''; Bimanese ''nonu''; Tetun ''nenu-k''; Leti and Asilulu ''nenu''; Leti (Moa) ''nienu''; Wetan ''neni''. It became Proto-Oceanic ''*ñoñu'', with cognates including Nali ''non''; Leipon and Wogeo ''ñoñ''; Bipi ''ñoy''; Gitua and Rarotongan ''nono''; Gilbertese ''non''; Motu, Tongan, Niue, Futunan, Samoan, Tuvaluan, Kapingamarangi, Nukuoro, and Anuta ''nonu''; and Hawaiian ''noni'' (from which the English name is derived from). In some languages the meaning has shifted to mean "small tree" or "shrub" or to the closely related ''Morinda umbellata'' and '' Morinda bracteata''.

In Western Malayo-Polynesian, another term that can be reconstructed is Proto-Western Malayo-Polynesian ''*baŋkudu'', which may have referred to a different species of '' Morinda'' originally. Its cognates including Tagalog and Cebuano ''bangkúro''; Agutaynen ''bangkoro''; Tausug, Toba Batak, and Balinese ''bangkudu''; Sundanese ''cangkudu''; Sasak ''bengkudu''; Mongondow ''bongkudu;'' and Malay ''mengkudu''.

There are also smaller cognate sets, like Proto-Philippine ''*apatut'' for the tree and Proto-Oceanic ''*gurat'' and ''*kurat'' for the red dye produced from the tree.

''Musa'' (bananas)

The earliest domestication of bananas ('' Musa'' spp.) were initially from naturally occurring parthenocarpic (seedless) individuals of ''Musa acuminata banksii'' in New Guinea, before the arrival of Austronesian-speakers. Numerous phytoliths of bananas have been recovered from the Kuk Swamp archaeological site and dated to around 10,000 to 6,500 BP. From New Guinea, cultivated bananas spread westward into Island Southeast Asia through proximity (not migrations). They hybridized with other (possibly independently domesticated) subspecies of ''Musa acuminata'' as well as ''Musa balbisiana'' in the Philippines, northern New Guinea, and possibly Halmahera. These hybridization events produced the triploid cultivars of bananas commonly grown today. From Island Southeast Asia, they became part of the staple crops of Austronesian peoples and were spread during their voyages and ancient maritime trading routes into Oceania, East Africa, South Asia, and Indochina.

These ancient introductions resulted in the banana subgroup now known as the "true" plantains, which include the East African Highland bananas and the Pacific plantains (the Iholena and Maoli-Popo'ulu subgroups). East African Highland bananas originated from banana populations introduced to Madagascar probably from the region between Java, Borneo, and New Guinea; while Pacific plantains were introduced to the Pacific Islands from either eastern New Guinea or the Bismarck Archipelago.

A second wave of introductions later spread bananas to other parts of tropical Asia, particularly Indochina and the Indian Subcontinent.

''Musa abaca'' (abacá)

Abacá (''Musa textilis''), also known as Manila Hemp, is grown traditionally for its fiber in the Philippines. It was once one of the world's premier fibers, valued for its use in soft, lustrous, and silky fabrics. It was a major luxury export of the Philippines during the Colonial Era, and was introduced to Hawaii and Central America by Europeans. It has since been replaced by synthetic fibers like rayon and nylon.

''Musa'' × ''troglodytarum'' (fe'i banana)

Fe'i bananas (''Musa'' × ''troglodytarum''), also spelled Fehi or Féi, are banana cultivars unique to Melanesia, the Maluku Islands, and Polynesia. Unlike other domesticated banana cultivars which are derived from ''Musa acuminata'' and ''Musa balbisiana'', fe'i bananas are believed to be hybrids derived from entirely different species. Proposed progenitors of fe'i bananas include '' Musa jackeyi'', '' Musa lolodensis'', '' Musa maclayi'', and ''Musa peekelii'', all of which are native to New Guinea and surrounding islands. Like other bananas, they were spread eastwards to Polynesia for use as food. However, they are absent in Island Southeast Asia, reaching only as far as the Maluku Islands.

''Oryza sativa'' (rice)

Rice (''Oryza sativa'') is one of the most ancient Austronesian staples, and is likely to have been originally domesticated by their ancestors long before the Austronesian expansion. It remains the main crop plant cultivated in Island Southeast Asia.

There are two most likely centers of domestication for rice as well as the development of the wetland agriculture technology. The first, and most likely, is in the lower Yangtze River, believed to be the homelands of early Austronesian speakers and associated with the Kauhuqiao, Hemudu, Majiabang, and Songze cultures. It is characterized by typical Austronesian innovations, including stilt houses, jade carving, and boat technologies. Their diet were also supplemented by acorns, water chestnuts, foxnuts, and pig domestication.

The second is in the middle Yangtze River, believed to be the homelands of the early Hmong-Mien-speakers and associated with the Pengtoushan and Daxi cultures. Both of these regions were heavily populated and had regular trade contacts with each other, as well as with early Austroasiatic speakers to the west, and early Kra-Dai speakers to the south, facilitating the spread of rice cultivation throughout southern China.

The spread of ''japonica'' rice cultivation to Southeast Asia started with the migrations of the Austronesian Dapenkeng culture into Taiwan between 5,500 and 4,000 BP. The Nanguanli site in Taiwan, dated to ca. 4,800 BP, has yielded numerous carbonized remains of both rice and millet in waterlogged conditions, indicating intensive wetland rice cultivation and dryland millet cultivation.

From about 4,000 to 2,500 BP, the Austronesian expansion began, with settlers from Taiwan moving south to colonize Luzon in the Philippines, bringing rice cultivation technologies with them. From Luzon, Austronesians rapidly colonized the rest of Island Southeast Asia, moving westwards to Borneo, the Malay Peninsula and Sumatra; and southwards to Sulawesi and Java. By 2,500 BP, there is evidence of intensive wetland rice agriculture already established in Java and Bali, especially near very fertile volcanic islands.

However, rice (as well as dogs and pigs) did not survive the first Austronesian voyages into Micronesia due to the sheer distance of ocean they were crossing. These voyagers became the ancestors of the Lapita culture. By the time they migrated southwards to the Bismarck Archipelago, they had already lost the technology of rice farming, as well as pigs and dogs. However, knowledge of rice cultivation is still evident in the way they adapted the wetland agriculture techniques to taro cultivation. The Lapita culture in Bismarck reestablished trade connections with other Austronesian branches in Island Southeast Asia.

The Lapita culture also came into contact with the non-Austronesian ( Papuan) early agriculturists of New Guinea and introduced wetland farming techniques to them. In turn, they assimilated their range of indigenous cultivated fruits and tubers, as well as reacquiring domesticated dogs and pigs, before spreading further eastward to Island Melanesia and Polynesia.

Rice, along with other Southeast Asian food plants, were also later introduced to Madagascar, the Comoros, and the coast of East Africa by around the 1st millennium CE by Austronesian sailors from the Greater Sunda Islands.

Much later Austronesian voyages from Island Southeast Asia succeeded in bringing rice to Guam during the Latte Period (1,100 to 300 BP). Guam is the only island in Oceania where rice was grown in pre-colonial times.

''Pandanus'' (pandan)

Pandanus (''Pandanus'' spp.) are very important cultivated plants in the Pacific, second only in importance and pervasiveness to coconuts. Every part of the plant is utilized, including for food, building materials, traditional medicine, and fiber and weaving materials in various cultures in Austronesia. The plants (particularly the fragrant flowers) also had spiritual significance among the native animist Austronesian religions.

Pandanus were also profoundly crucial in enabling the Austronesian expansion. Their leaves were traditionally woven into mats used in the sails for Austronesian outrigger ships. Sails allowed Austronesians to embark on long-distance voyaging. In some cases, however, they were one-way voyages. The failure of pandanus to establish populations in Rapa Nui and Aotearoa is believed to have isolated their settlements from the rest of Polynesia.

The word for pandanus in Austronesian languages is derived from Proto-Austronesian ''*paŋudaN'', which became Proto-Oceanic ''*padran'' and Proto-Polynesian ''*fara'', the latter two usually referring specifically to ''Pandanus tectorius''. Cognates in modern Austronesian languages include Kanakanavu ''pangətanə''; Thao and Bunun ''panadan''; Tagalog ''pandan''; Chamorro ''pahong''; Ratahan ''pondang''; Malay ''pandan'' (from which the English name is derived from); Manggarai ''pandang''; Malagasy ''fandrana''; Lau ''fada-da''; Fijian ''vadra''; Samoan ''fala''; Tongan ''fā''; Tahitian ''fara''; Hawaiian ''hala''; and Māori ''whara'' or ''hara''. Note that among the Formosan languages of Indigenous Taiwanese, the meaning of the words have largely shifted to mean "pineapple", a physically similar non-native European-introduced plant. In Māori, as well, the meaning has shifted to '' Astelia'' spp. and ''Phormium tenax'' (harakeke), similar plants used for weaving, since pandanus did not survive the voyage into Aotearoa.

Pandanus grow well in island habitats, being very salt-tolerant and easy to propagate, making them ideal plants for early Austronesian sailors. Like coconuts, they grow predominantly along strandlines, mangrove forests, and other coastal ecosystems. They can also be found in the understory of forests in larger islands. Others may also be found in highland groves, likely planted by humans. Both pandanus and coconuts are adapted to withstand the strong winds of the frequent typhoons of the Indo-Pacific. The greatest center of diversity of ''Pandanus'' is the western Pacific and Island Southeast Asia. The genus has around 600 species, but the most important and the most widespread group of species in Austronesian cultures and is the ''Pandanus tectorius'' complex.

''Pandanus tectorius'' in Oceania show evidence of long cultivations, with hundreds of different selectively bred cultivars which are primarily propagated through cuttings. These varieties often have different names in local languages and have different physical characteristics. The varieties are predominantly distinguished by the color and edibility of their fruit, but they may also be differentiated based on other criteria like the color and shape of their leaves used for weaving.

Very old fossils of ''Pandanus tectorius'' have been recovered from Hawaii, dated to more than 1.2 million years old. This indicates that the plants once colonized Hawaii (and likely the rest of the Pacific islands) naturally through their buoyant fruits. However, useful domesticated varieties were carried by Austronesians from island to island. Especially since wild pandanus have calcium oxalate crystals (raphides) in their fruit tissue. They cause itchiness and irritation when eaten raw and thus need to be cooked. Domesticated varieties which have less raphides (which are also usually less fibrous and more nutritious), were therefore valued . It is thus considered both native and introduced. There are also fossil evidence of pandanus fruits being harvested for food in New Guinea from archaeological sites dated to around 34,000 to 36,000 BP.

Other important species of pandanus utilized by Austronesians include '' Pandanus amaryllifolius'', '' Pandanus odorifer'', '' Pandanus furcatus'', ''Pandanus julianettii'', ''Pandanus simplex'', ''Pandanus utilis'', '' Pandanus dubius'', and ''Pandanus whitmeeanus'', among many others. ''Pandanus odorifer'' is widespread in the region from western Micronesia, to Island Southeast Asia and South Asia. It is possibly a subspecies of ''Pandanus tectorius'' and they hybridize readily. '' Pandanus amaryllifolius'', the pandan, is another important species widely used as a spice in the cuisines of Southeast Asia for their vanilla-like fragrant leaves.

''Piper'' (peppers)

Peppers (''Piper (genus), Piper'') ancestrally cultivated by Austronesians include the betel (''Piper betle''), cubeb pepper (''Piper cubeba''), kava (''Piper methysticum''), and the Javanese long pepper (''Piper retrofractum''). Many others were also harvested from the wild for medicinal or religious purposes, including ''Piper caducibracteum'', ''Piper excelsum'', ''Piper ornatum'', and ''Piper sarmentosum''. Black pepper (''Piper nigrum'') and long pepper (''Piper longum, Piper longum'') were also extensively cultivated in Island Southeast Asia after early contact by Austronesian traders with South India and Sri Lanka.

''Piper betle'' (betel)

The betel (''Piper betle'') is one of the two plants that comprise the main ingredients of paan, betel chewing, the other being the areca nut (''Areca catechu, Areca catechu''). It is one of the most ubiquitous practices of the Austronesians. It is consumed by taking a leaf of betel, wrapping it around an areca nut and some Lime (material), lime (obtained from grinding seashells), and then chewing it for some time. It is a stimulant, inducing slight dizzines followed by euphoria and alertness. It is also highly addictive, damages the teeth and gums, and stains the teeth red.

Based on archaeological, linguistic, and botanical evidence, betel chewing is most strongly associated with Austronesian cultures, despite its widespread adoption by neighboring cultures in prehistoric and historic times. The original range of betel is unknown, but ''Areca catechu'' is known to be originally native to the Philippines, where it has the greatest morphological diversity as well as the most number of closely related endemic species. It is unknown when the two were combined, as areca nut alone can be chewed for its narcotic properties. In eastern Indonesia, however, leaves from the wild ''Piper caducibracteum'' (known as ''sirih hutan'') are also harvested and used in place of betel leaves.

The oldest unequivocal evidence of betel chewing is from the Philippines. Specifically that of several individuals found in a burial pit in the Duyong Cave site of Palawan island dated to around 4,630±250 BP . The dentition of the skeletons are stained, typical of betel chewers. The grave also includes ''Anadara'' shells used as containers of lime, one of which still contained lime. Burial sites in Bohol dated to the first millennium CE also show the distinctive reddish stains characteristic of betel chewing. Based on linguistic evidence of how the reconstructed Proto-Austronesian term ''*buaq'' originally meaning "fruit" came to refer to "areca nut" in Proto-Malayo-Polynesian, it is believed that betel chewing originally developed somewhere within the Philippines shortly after the beginning of the Austronesian expansion (~5,000 BP). From the Philippines, it spread back to Taiwan, as well as onwards to the rest of Austronesia.

It reached Micronesia at around 3,500 to 3,000 BP with the Austronesian voyagers, based on both linguistic and archaeological evidence. It was also previously present in the Lapita culture, based on archaeological remains from Mussau dated to around 3,600 to 2,500 BP. But it did not reach Polynesia further east. It is believed that it stopped in the Solomon Islands due to the replacement of betel chewing with the tradition of kava drinking prepared from the related ''Piper methysticum''. It was also diffused into East Africa via the Austronesian settlement of Madagascar and the Comoros by around the 7th century.

The practice also diffused to the cultures the Austronesians had historical contact with. It reached South Asia by 3,500 BP, through early contact of Austronesian traders from Sumatra, Java, and the Malay Peninsula with the Dravidian languages, Dravidian-speakers of Sri Lanka and southern India. This also coincides with the introduction of Southeast Asian plants like ''Santalum album'' and '' Cocos nucifera'', as well as the adoption of the Austronesian outrigger ship and crab-claw sail technologies by Dravidian-speakers. It Mainland Southeast Asia by 3,000 to 2,500 BP through trade with Borneo, as well as the settlement of the Champa polities in southern Vietnam. From there, it was spread northwards into China. Lastly, it reached Northern India by 500 BP through trade in the Bay of Bengal. From there it was spread westwards into Persia and the Mediterranean.

There are very old claims of betel chewing dating to at least 13,000 BP at the Kuk Swamp site in New Guinea, based on probable ''Areca'' sp. recovered. However, it is now known that these might have been due to modern contamination of sample materials. Similar claims have also been made at other older sites with ''Areca'' sp. remains, but none can be conclusively identified as ''A. carechu'' and their association with betel peppers is tenuous or nonexistent.

There are numerous cognate sets reconstructible in Austronesian languages relating to various aspects of betel chewing. Ranging from chewing something without swallowing to equipment used to climb areca nut palms to the betel spittle. One cognate set that can be reconstructed for betel pepper is Proto-Western Malayo-Polynesian ''*Rawed'' which became Proto-Philippine ''*gawed'', with cognates including Yami ''gaod'', Itbayaten ''gawed''; Ilocano ''gawéd''; Isneg ''khawád''; Casiguran Dumagat language, Casiguran Dumagat ''gawə́d''; and Ibaloy language, Ibaloy ''kawed''; Balangaw language, Balangaw ''lawɨ'd''; Kalagan language, Kalagan ''lawód''; and Kenyah ''auat'' or ''awet''.

Two other cognate sets reached into Oceania. The first is Proto-Malayo-Polynesian ''*pu-pulu'', which became Proto-Oceanic ''*[pu-]pulu''. Cognates include Mussau ''ulo''; Loniu ''pun''; Bipi ''pun'' or ''puepun''; Lukep language, Lukep ''ul''; Takia ''ful''; Gedaged ''fu''; Manam ''ulusalaga''; and Bugotu ''vu-vulu''. The other is Proto-Meso-Melanesian ''*siqa(r,R)(a)'', with cognates including Kara language (Papua New Guinea), Kara and Lihir language, Lihir ''sie''; Tabar language, Tabar ''sia''; Patpatar language, Patpatar ''sier''; Tolai ''ier''; Nehan ''hiara''; Petats ''sil''; Teop language, Teop ''hia(kuru)''; Tinputz language, Tinputz ''(ta)sian''; Banoni language, Banoni ''siɣana''; and Marovo ''hirata''.

''Piper cubeba'' (cubeb pepper)

The cubeb pepper (''Piper cubeba'') are native to Island Southeast Asia. Like ''Piper retrofractum'', however, it was only cultivated extensively in the Greater Sunda Islands for the spice trade. The Javanese protected the monopoly of the trade by sterilizing the seeds before trading them. It has a pungent smell, often compared to allspice, quite unlike that of the other culinary peppers. It also has a slightly bitter taste. It is notable as having reached as far as Greece during ancient times via the Silk Road. It was a valuable rare spice in Medieval Europe and the Medieval Middle East, Middle East, reputed to have medicinal and magical properties. Medieval Arab physicians commonly used it for a range of treatments, ranging from treating infertility to poison antidotes. It is mentioned in ''The Book of One Thousand and One Nights'' as well as in the travelogues of Marco Polo. Its trade waned during the Colonial Era when the Portuguese Empire banned its importation to promote the black pepper produced by its own colonies.

''Piper excelsum'' (kawakawa)

Kawakawa (''Piper excelsum'') is a small tree or shrub endemic to New Zealand and nearby Norfolk Island and Lord Howe Island. It was exploited by Austronesian settlers based on previous knowledge of the kava, as the latter could not survive in the colder climates of Aotearoa. The Māori name for the plant, ''kawakawa'', is derived from the same etymon as kava, but reduplicated. It is a sacred tree among the Māori people. It is seen as a symbol of death, corresponding to the rangiora (''Brachyglottis repanda'') which is the symbol of life. Boughs of kawakawa are often used in purification rituals.

However, kawakawa's resemblance to true kava is only superficial. Kawakawa roots do not have psychoactive properties. Instead, kawakawa's primary use is for traditional medicine.

''Piper methysticum'' (kava)

Kava (''Piper methysticum'') is a small tree or shrub believed to have been domesticated in either New Guinea or Vanuatu by Papuans. It is believed to be a domesticated variety of ''Piper subbullatum'' which is native to New Guinea and the Philippines.

It was spread by Austronesians after contact into the rest of Polynesia. It is endemic to Oceania and is not found in other Austronesian groups. Kava has great cultural and religious significance among Polynesians. The roots are pounded and mixed with water then strained through fibers. The resulting cloudy gray liquid is bitter with mildly psychoactive and narcotic properties, with a common effect being numbness around the lips and mouth. However, it is not hallucinogenic nor addictive. The potency of the root depends on the age of the plants. The leaves and roots can also be chewed directly resulting in a numbing effect and relaxation. It is traditionally consumed both in everyday social interactions and in religious rituals. Kava reached Hawaii, but it is absent in Aotearoa where it can not grow.

Consumption of kava is also believed to be the reason why betel chewing, ubiquitous elsewhere, was lost for Austronesians in Oceania.

According to Lynch (2002), the reconstructed Proto-Polynesian term for the plant, ''*kava'', was derived from the Proto-Oceanic term ''*kawaRi'' in the sense of a "bitter root" or "potent root [used as fish poison]". It originally referred to ''Zingiber zerumbet'', which was used to make a similar mildly psychoactive bitter drink in Austronesian rituals. Cognates for ''*kava'' include Pohnpeian ''sa-kau''; Tongan, Niue, Rapa Nui, Tuamotuan, and Rarotongan ''kava''; Samoan and Marquesan ''ava''; and Hawaiian ''awa''. In some languages, most notably Māori ''kawa'', the cognates have come to mean "bitter", "sour", or "acrid" to the taste.

In the Cook Islands, the reduplicated forms of ''kawakawa'' or ''kavakava'' are also applied to the unrelated members of the genus ''Pittosporum''. And in other languages like in Futunan, compound terms like ''kavakava atua'' refer to other species belonging to the genus ''Piper (genus), Piper''. The reduplication of the base form is indicative of falsehood or likeness, in the sense of "false kava".

''Piper retrofractum'' (Javanese long pepper)

The Javanese long pepper (''Piper retrofractum'') is native to Island Southeast Asia from the Philippines to Sumatra. Its northern range also extends to southern China, mainland Southeast Asia, Taiwan, and the Ryukyu Islands. However it was historically only cultivated in any great extent in the islands of Java and Bali, and surrounding islands, for the spice trade. Elsewhere it is mostly grown informally in the backyards of houses. It is very similar to the Indian long pepper (''Piper longum'') and is used in the same way in Southeast Asian cuisine.

''Saccharum'' (sugarcane)

There are two centers of domestication for sugarcane (''Saccharum'' spp.): one for ''Saccharum officinarum'' by Papuan people, Papuans in New Guinea and another for ''Saccharum sinense'' by Austronesian peoples, Austronesians in Taiwan and southern China. Papuans and Austronesians originally primarily used sugarcane as food for domesticated pigs. The spread of both ''S. officinarum'' and ''S. sinense'' is closely linked to the migrations of the Austronesian peoples.

''Saccharum officinarum'' was first domesticated in New Guinea and the islands east of the Wallace Line by Papuan people, Papuans, where it is the modern center of diversity. Beginning at around 6,000 BP they were selectively bred from the native ''Saccharum robustum''. From New Guinea it spread westwards to Island Southeast Asia after contact with Austronesians, where it hybridized with ''Saccharum spontaneum''.

The second domestication center is mainland southern China and Taiwan where ''S. sinense'' (though other authors identify it as ''S. spontaneum'') was one of the original major crops of the Austronesian peoples from at least 5,500 BP. Introduction of the sweeter ''S. officinarum'' may have gradually replaced it throughout its cultivated range in Island Southeast Asia. From Island Southeast Asia, ''S. officinarum'' was spread eastward into Polynesia and Micronesia by Austronesian voyagers as a canoe plant by around 3,500 BP. It was also spread westward and northward by around 3,000 BP to China and India by Austronesian traders, where it further hybridized with ''Saccharum sinense'' and ''Saccharum barberi''. From there it spread further into western Eurasia and the Mediterranean.

The reconstructed word for "sugarcane" in Proto-Austronesian is ''*CəbuS'' or ''*təbuS'', which became Proto-Malayo-Polynesian ''*təbuh'', Proto-Oceanic ''*topu'', and Proto-Polynesian ''*to''. Modern cognates include Papora-Hoanya language, Hoanya and Bunun ''sibus''; Rukai ''cobosə'' or ''tibóso''; Tagalog ''tubó''; Chamorro ''tupu''; Murik Kayan language, Murik Kayan ''tebu''; Malay ''tebu''; Old Sundanese language, Old Sundanese ''teuwu''; Sundanese language, Modern Sundanese ''tiwu''; Ansus language, Ansus ''tobu''; Malmariv language, Malmariv ''tov''; Fijian ''dovu''; Mele-Fila language, Mele-Fila and Takuu ''toro''; Samoan ''tolo''; Sudest language, Tagula ''ro''; Pohnpeian ''cheu''; Tahitian ''to''; Pukapukan language, Pukapukan, Rarotongan, and Tongan ''tō''; Hawaiian ''kō''; and Rapa Nui ''to'' or ''ta''. In Malagasy, however, the word for "sugarcane" is ''fary'', which is instead derived from Proto-Austronesian ''*pajey'', meaning "rice".

''Solanum''

Several species of Solanum have been utilised as food and medicine by the Austronesian people. Species cultivated include Kangaroo apple (''Solanum aviculare''), poroporo (''Solanum laciniatum''), Indian nightshade (''Solanum lasiocarpum''), pacific tomato (''Solanum repandum'') and cannibals tomato (''Solanum viride'').

''Syzygium''

Trees in the genus ''Syzygium'' contain some of the most important fruit trees among Austronesian peoples. Species cultivated or harvested for their edible fruit include the Java plum (''Syzygium cumini''), jambos (''Syzygium jambos''), lubeg (''Syzygium lineatum''), swamp maire (''Syzygium maire''), mountain apple (''Syzygium malaccense''), lipote (''Syzygium polycephaloides''), and the Java apple (''Syzygium samarangense''), among others. Two species are also important sources of spice: the clove tree (''Syzygium aromaticum'') and Indonesian bay leaf (''Syzygium polyanthum'').

''Syzygium malaccense'' (mountain apple)

The mountain apple (''Syzygium malaccense'') along with the closely related species like the water apple (''Syzygium aqueum'') and the Java apple (''Syzygium samarangense''), are native throughout Island Southeast Asia and were cultivated since prehistory. They were all carried by Austronesians into the Pacific and planted deliberately.

They were valued primarily for their abundant edible fruits. It is also used for timber (usually for building houses) and parts of the trees are used in traditional medicine. The attractive flowers are also worn as personal hair adornments and in making lei (garland), leis. They were primarily propagated through cuttings by Melanesians and Polynesians. The groves of mountain apples found in the Pacific are often remnants of ancient plantings, as the seeds of the fruits are too large to be dispersed by the native birds. Related species endemic to the Pacific Islands were also utilized similarly, like ''Syzygium corynocarpum'' and ''Syzygium neurocalyx''.

There numerous names for mountain apples in Austronesian languages. In the Philippines, the terms can be reconstructed to Proto-Philippine ''*makúpa'', with cognates including Ilocano, Aklanon, and Cebuano ''makúpa''; and Tagalog and Bikol ''makópa''.

In Oceania, there are several cognate sets reconstructible for mountain apples and related species. Four of which are ''*pokaq'', ''*marisapa'', ''*sakau'' and ''*cay'', with limited reflexes and may have originally referred to other species. The most widespread cognate set, however, can be reconstructed to Proto-Oceanic ''*kapika''. Its cognates include Mussau ''kaviu''; Seimat ''ahi'', Lou ''keik''; Maenge and Nakanai language, Nakanai ''gaiva''; Tami language, Tami ''kapig''; Yabem language, Yabem ''àing''; Motu ''gavika''; Bola language (Austronesian), Bola ''kavika''; Babatana language, Babatana ''kapika''; gela language, Gela ''gaviga''; Kwara'ae ''afio''; Paamese language, Paamese ''ahie''; Wayan, Niue, East Uvean language, East Uvean, and Bauan ''kavika''; Tongan ''fekika''; Anutan language, Anutan ''kapika''; Marquesan ''kehika''; Mangarevan language, Mangarevan ''keika''; Tahitian ''ahia''; Hawaiian ''oohiaai''; Rarotongan ''kaika''; and Māori ''kahika''. In Māori, the names have shifted to ''Metrosideros fulgens'', which have similar-looking flowers, as Malay apples did not survive into Aotearoa.

''Tacca leontopetaloides'' (Polynesian arrowroot)

Polynesian arrowroot (''Tacca leontopetaloides'') is another ancient Austronesian root crop closely related to yams. It is originally native to Island Southeast Asia. It was introduced throughout the entire range of the Austronesian expansion, including Micronesia, Polynesia, and Madagascar. Polynesian arrowroot have been identified as among the cultivated crops in Lapita culture, Lapita sites in Palau, dating back to 3,000 to 2,000 BP. It was also introduced to Sri Lanka, southern India, and possibly also Australia through trade and contact.

Polynesian arrowroot was a minor staple among Austronesians. The roots are bitter if not prepared properly, thus it was only cultivated as a secondary crop to staples like ''Dioscorea alata'' and ''Colocasia esculenta''. Its importance increased for settlers in the Pacific Islands, where food plants were scarcer, and it was introduced to virtually all the inhabited islands. They were valued for their ability to grow in low islands and atolls, and were often the staple crops in islands with these conditions. In larger islands, they were usually allowed to grow feral and were useful only as famine food. Several cultivars have been developed in Polynesia due to the thousands of years of artificial selection. The starch extracted from the root with traditional methods can last for a very long time, and thus can be stored or traded. The starch can be cooked in leaves to make starchy puddings. Due to the introduction of modern crops, it is rarely cultivated today.

The names for Polynesian arrowroot in Austronesian languages reflect its secondary importance as a crop. They are often reassignments from names of other starch crops, rather than specifically being for Polynesian arrowroot. Usually, the names of Polynesian arrowroot are transferred from the names of the sago palms (''Metroxylon sagu''), giant swamp taros ('' Cyrtosperma merkusii''), and fermented breadfruit (''Artocarpus altilis'').

Derivations from Proto-Malayo-Polynesian ''*sagu'' ("sago palm"), include Chamorro and Toba Batak ''sagu''. Derivations from Proto-Polynesian ''*mā'' ("fermented breadfruit"), included Tongan ''māhoaa''; Tokelauan language, Tokelauan ''mahoā''; Anutan language, Anutan ''maoa''; East Futunan language, East Futunan ''māsoā''; Samoan ''māsoā''; and Tuvaluan ''māsoa''. Derivations from Proto-Polynesian ''*bulaka'' (giant swamp taro) include Patpatar language, Patpatar and Tolai ''pulaka''. Derivations from Proto-Austronesian ''*biRaq'' (giant taro) include Äiwoo ''(to)piya''. And finally, derivations from Proto-Oceanic ''Rabia'' (sago) include Bauan ''yabia''; and Pileni language, Pileni, Rarotongan, and Hawaiian ''pia''.

''Talipariti tiliaceum'' (sea hibiscus)

Sea hibiscus (''Talipariti tiliaceum'') is a common tree in beaches in the tropical Indo-Pacific. It is widely used by Austronesian peoples for timber and fiber. It has several subspecies, two of which are endemic to the Philippines and Sulawesi, with the rest widespread throughout its range or native to large regions of Southeast Asia and the Pacific. The seeds remain viable for months after floating in the sea. However, no remains of beach hibiscus have been recovered from Polynesia prior to the Austronesian arrival, making it clear that they were introduced by Austronesian voyagers.

The wood is soft and not very durable, so it is mostly only used for products like carvings, spears, bowls, and bracelets. However, it is also resistant to saltwater and thus can be used to make small canoes and outriggers. The wood is also preferred for fire making by friction. The fiber extracted from the bark is widely used to make cordage and for caulking. The bark is also used in the production of tempeh in Southeast Asia, and kava drinks in Polynesia. The attractive flowers are commonly made into lei (garland), leis in Hawaii.

The terms for beach hibiscus can be reconstructed to Proto-Malayo-Polynesian ''*baRu'', which became Proto-Oceanic ''*paRu'' and Proto-Micronesian ''*kili-fau''. Modern cognates include Itbayaten ''vayu''; Ilocano ''bagó''; Kankana-ey ''bágo''; Chamorro ''pagu''; Tagalog ''balibago''; Cebuano ''malabago'' or ''maribago''; Maranao ''bago''; Ngaju Dayak ''baro''; Malagasy ''baro'' or ''varo''; Malay ''baru''; Javanese, Rembong, and Kambera language, Kambera ''waru''; Sangir language, Sangir and Soboyo language, Soboyo ''bahu''; Makasarese language, Makasar ''baru''; Erai ''hau''; Leti ''paru''; Paulohi language, Paulohi ''haru''; Buruese ''fahu''; Gitua ''paru''; Mailu language, Mailu ''waru''; Mota ''var'' or ''varu''; Sye ''nau'' or ''vau''; Anejom language, Anejom ''n-hau''; Fijian ''vau''; Tongan and Samoan ''fau''; Rotuman, Rennellese, and Hawaiian ''hau''; and Māori ''whau''.

In addition, there are numerous terms relating to the use of sea hibiscus for cordage and fiber in various Austronesian languages which can be traced back to Proto-Malayo-Polynesian or Proto-Austronesian, like ''*Calis'', "rope".

''Thespesia populnea'' (Pacific rosewood)

The Pacific rosewood (''Thespesia populnea'') is closely related to beach hibiscus. They are similar in appearance and grow in the same habitats, thus they are commonly confused with each other. It is also used similarly among Austronesian cultures, being one of the main sources of bast fibers for the production of cordage and wood for Austronesian outrigger ships and carving. Pacific rosewood is native to the Old World tropics. Like beach hibiscus, the seeds remain viable for months after floating in the sea but no remains of ''T. populnea'' have been recovered from Polynesia prior to the Austronesian expansion. Thus it is regarded as deliberate introductions by Austronesian settlers.

The trees were regarded as sacred in Polynesian culture, and were commonly planted in ''marae'' sites along with trees like ''Ficus'', ''Fagraea berteroana'', ''Casuarina equisetifolia'' and ''Calophyllum inophyllum''.

The terms for Pacific rosewood can be reconstructed to Proto-Malayo-Polynesian ''*balu'', with cognates including Itbayaten ''valu''; Malagasy ''válo''; Simeulue language, Simeulue ''falu''; Nggela language, Ngela ''valu''; Arosi ''haru''; and Lonwolwol language, Lonwolwol ''bal''. Another term which extends to Oceanic is Proto-Malayo-Polynesian ''*banaRu'' with cognates including Hanunó'o ''banagu''; Tolai ''banar''; Patpatar language, Patpatar ''banaro''; Mota ''vanau''; and Pohnpeian ''pana''.

In Eastern Polynesia, most modern names can be reconstructed back to Proto-Eastern Oceanic ''*milo'', with cognates including Tongan, Niue, Samoan, and Hawaiian ''milo''; Rapa Nui, Tahitian language, Tahitan, Tuamotuan, and Māori ''miro''; and Marquesan ''mio''. In some islands, the names have shifted to refer to trees that are used similarly, like ''Prumnopitys ferruginea'' in Aotearoa and ''Sophora toromiro'' in Rapa Nui.

Zingiberaceae (ginger family)

Gingers (family (biology), family Zingiberaceae) were cultivated extensively by Austronesians for food, medicine, weaving materials, and for religious purposes. The most commonly cultivated species include the lengkuas (''Alpinia galanga''), fingerroot (''Boesenbergia rotunda''), turmeric (''Curcuma longa''), torch ginger (''Etlingera elatior''), and ginger (''Zingiber officinale''). Other species were also exploited at a smaller scale or harvested from the wild, including dwarf cardamom (''Alpinia nutans''), panasa cardamom (''Amomum acre''), white turmeric (''Curcuma zedoaria''), jiddo (''Hornstedtia scottiana''), white ginger lily (''Hedychium coronarium''), and bitter ginger (''Zingiber zerumbet, Zingiber zerumbet'').

''Alpinia galanga'' (lengkuas)

The lengkuas (''Alpinia galanga'') is native to Southeast Asia. Its original center of cultivation during the spice trade was Java, and today it is still cultivated extensively in Island Southeast Asia, most notably in the Greater Sunda Islands and the Philippines. It is valued for its use in food and for traditional medicine and is regarded as being superior to ginger. It has a pungent smell reminiscent of black pepper. The red and white cultivars are often used differently, with the red cultivars being primarily medicinal, and the white cultivars being primarily a spice. Lengkuas is also the source of the leaves used to make ''nanel'' among the Kavalan people of Taiwan, a rolled leaf instrument used as a traditional children's toy common among Austronesian cultures.

Lengkuas can be reconstructed to Proto-Western Malayo-Polynesian ''*laŋkuas'', with cognates including Ilokano language, Ilokano ''langkuás''; Tagalog, Bikol, Kapampangan, Visayan, and Manobo ''langkáuas'' or ''langkáwas''; Aklanon ''eangkawás''; Kadazan Dusun language, Kadazan Dusun ''hongkuas''; Ida'an language, Ida'an ''lengkuas''; Ngaju Dayak '' langkuas''; Iban ''engkuas''; and Malay ''lengkuas'' (from which the English name is derived from). Some of the names have become generalized and are also applied to other species of ''Alpinia'' as well as for ''Curcuma zedoaria''.

''Curcuma longa'' (turmeric)

There is strong evidence that turmeric (''Curcuma longa'') as well as the related white turmeric (''Curcuma zedoaria'') were independently domesticated by Austronesian peoples, Austronesians. Turmeric has a very widespread distribution and names that pre-date contact with India, being found among all Austronesian regions with the exception of Taiwan. However, it was seemingly originally domesticated for the production of dyes, eventually contributing to the words for "yellow" and "red" in various Austronesian languages.

The plant is important in the Philippines and Indonesia as a traditional dye for clothing and food coloring. It was particularly valued for coloring food offerings to spirits as well as body painting in religious rituals or social ceremonies. It is also used as a spice, as medicine and as food. Similar uses are also found in the other islands settled by Austronesians, including Madagascar and the Comoros in East Africa. In Micronesia, it was a valuable trade item acquired from Yap Island, Yap. In Polynesia and Melanesia, they are primarily used as body paint in rituals or as a cosmetic. The latter regions have been isolated for centuries from the rest of Island Southeast Asia prior to European contact.

There are two main cognate sets for ''C. longa'' and ''C. zedoaria'' (both of which produce yellow dye) in Austronesian languages. The first is reconstructed as Proto-Malayo-Polynesian ''*kunij'' which originally referred to turmeric. Its cognates include Ilocano, Kankanaey language, Kankana-ey, and Isneg ''kúnig''; Bontoc ''kúnəg''; Ifugao ''ūnig''; Casiguran Dumagat language, Casiguran Dumagat ''kuneg''; Iban and Malay ''kunyit''; Toba Batak ''hunik''; Javanese ''kunir''; Sangir language, Sangir and Tae' ''kuni''; Uma ''kuni''; Rembong ''kunis''; Ngadha ''wuné''; and Manggarai ''wunis''. In Malagasy and Betsimisaraka language, Betsimisaraka, the cognates ''hónitra'' and ''húnitra'' have shifted meaning to a different plant used to make red dye. Other cognates like Ilocano ''kimmúnig''; Uma ''mo-kuni'', and Tae' ''pakuniran'' all mean "yellow" or "to dye something yellow".

The other cognate set is derived from reconstructed Proto-Western-Malayo-Polynesian *temu, and originally meant ''C. zedoaria'' which was used primarily as a spice. It also sometimes shifted to ginger and other ginger-like plants used for cooking (rather than dye production). Its cognates include Kapampangan and Balinese ''tamu''; Tagalog ''támo''; Visayan ''tamangyan''; Western Bukidnon language, Bukidnon ''tamohilang''; Bikol ''tamahilan'' or ''tamaylan''; Malay, Javanese, and Sasak ''temu''; Makasarese ''tammu''; and Malagasy ''tamutamu''. In other Austronesian languages in East Africa, however, the other cognates mean "yellow", including Bushi language, Comorian Shibushi and Antemoro people, Antemoro ''tamutamu''; and Antambahoaka and Antankarana language, Antankarana ''manamutamu''.

In Proto-Oceanic, there are two main cognate sets derived from reconstructed ''*aŋo'' and ''*deŋ(w)a'', both are unrelated to the Proto-Malayo-Polynesian etymons. The latter probably originally applied to the dye produced from turmeric, while the former referred originally to the plant itself. Cognates include Fijian ''cango''; and Tongan and Rennellese ''ango''. Cognates that mean "yellow" also exist in numerous other languages in Near Oceania.

''Zingiber officinale'' (ginger)

Ginger (''Zingiber officinale'') is native to Island Southeast Asia and was probably originally domesticated by Austronesians. It is an ancient and ubiquitous crop among Austronesians, reaching all the way to Remote Oceania and Madagascar. Aside from being used for cuisine, ginger appears to have significant religious and medicinal roles in early Austronesian cultures, based on the Gloss (annotation), glosses it acquired. Ginger were chewed by shamans and spat out intermittently in rituals for healing, warding, and blessing ships.

In Proto-Austronesian, the terms for ginger can be reconstructed to ''*dukduk''. With cognates including Pazeh language, Pazeh ''dukuduk''; Thao ''suksuk''; Tsou ''cucu''; and Saaroa language, Saaroa ''suusuku''. This was replaced by ''*laqia'' in languages south of Taiwan.

The terms for ginger beyond Taiwan can be reconstructed to Proto-Malayo-Polynesian ''*laqia'', which became Proto-Oceanic ''*laqia'' and Proto-Central Polynesian ''*laya''. Cognates include Ilocano, Agta language, Agta, Isneg, Itawis, Kankana-ey, and Casiguran Dumagat language, Casiguran Dumagat ''layá''; Bontoc, Ifugao and Kapampangan ''láya''; Batad Ifugao language, Batad Ifugao ''lāya''; Tagalog ''luya''; Bikol ''láya''; Visayan ''luya''; Tboli language, Tboli ''leiye''; Kadazan Dusun language, Kadazan Dusun ''hazo''; Tombonuwo language, Tombonuwo and Abai Sembuak language, Abai Sembuak ''layo''; Ida'an language, Ida'an Begak ''lejo''; Basap language, Basap, Long Anap Kenyah, Sangir language, Sangir, and Tontemboan ''lia''; Lun Dayeh and Kelabit ''lieh''; Berawan language, Berawan and Miriʼ language, Miriʼ ''lejeh''; Narum language, Narum ''lejieh''; Kenyah (Òma Lóngh) ''lezó''; Murik Kayan language, Murik and Iban ''lia''; Kelai language, Kelai and Wahau Kenyah language, Wahau Kenyah ''je''; Segai language, Segai ''aljo''; Modang language, Modang ''lejao̯''; Kiput language, Kiput ''lecih''; Bintulu language, Bintulu ''leza''; Iban ''lia''; Dayak language, Dayak ''roii''; Jarai ''reya''; Malay ''halia''; Tialo language, Tialo ''loía''; Balaesang language, Balaesang ''láia''; Bare'e language, Bare'e ''leia''; Tae' language, Tae ''laia'' or ''laya''; Makasarese ''laia''; Muna ''longhia''; Bimanese ''rea''; Manggarai, Roti languages, Roti, Erai, Leti, Wetan. and Lamaholot language, Lamaholot ''lia''; and Sika language, Sika and Ngadha ''lea''; Kowiai and Kei language, Kei ''leii''. In Oceanic languages, cognates include Lou and Kairiru ''lei''; Penchal ''lai''; Ahus language, Ahus and Kurti language, Kurti ''liy''; Khehek language, Drehet ''lip''; Lindrou language, Lindrow ''ley''; Mussau and Wuvulu, Nehan language, Neham ''laia''; Tanga ''lae''; Lakalai ''la lahia''; Gitua ''laea''; Wedau language, Wedau ''naia''; 'Āre'āre and Arosi ''ria''; Saa language, Sa'a ''lie''; and Fijian ''cango laya''.

''Zingiber zerumbet'' (bitter ginger)

Bitter ginger (''Zingiber zerumbet'') is native to tropical Asia and Australasia. Like the ginger, was carried by Austronesian settlers all the way to Remote Oceania during prehistoric times. Thus it is likely that it was originally domesticated by Austronesians. Remains of bitter ginger have also been identified from the Kuk Swamp archaeological site in New Guinea at the Phase 1 layers dated to 10,220 to 9,910 BP. However, whether they were cultivated or simply exploited from the wild is unknown.

Bitter ginger is primarily used for traditional medicine. It also has mildly psychoactive properties when consumed, and thus had ritual importance among early Austronesian cultures. According to Lynch (2002), terms for bitter ginger in the sense of "bitter root" or "potent root [used as fish poison]", reconstructed as Proto-Oceanic ''*kawaRi'', is believed to have been transferred to the kava (''Piper methysticum''), which has similar properties and is also bitter-tasting, when Austronesians of the Lapita culture first encountered it among the indigenous non-Austronesian peoples in Melanesia.

Some reflexes of it still refer to bitter ginger, including Sissano language, Sissano ''(una)kaw''; Gapapaiwa ''kaware''; Tikopia language, Tikopia, Anutan language, Anutan, and Wallisian language, Wallisian ''kava-pui''; Samoan ''ava-pui''; Tahitian ''ava-puhi''; and Hawaiian ''awa-puhi''. Other reflexes also refer to other members of the genus ''Piper (genus), Piper'', to fish poison, or as words to describe bitter, sour, or acrid flavors.

In non-Oceanic languages, terms for bitter ginger can be reconstructed to Proto-Western Malayo-Polynesian ''*lampuyaŋ'', with cognates including Cebuano and Ngaju Dayak ''lampuyang''; Javanese ''lempuyang''; and Malay ''lempoyang''.

Animals

Domesticated, semi-domesticated, and commensal animals carried by Austronesian voyagers include the following:

''Bubalus bubalis'' (water buffalo)

Water buffaloes are essential work animals in Austronesian paddy field agriculture and were carried along with rice to Island Southeast Asia from mainland Asia. Early introductions were specifically of the swamp-type water buffaloes (like the carabao), although they are increasingly being replaced by river-type water buffaloes imported from South Asia in recent times.

The earliest remains of water buffaloes in Island Southeast Asia with signs of domestication comes from multiple fragmentary skeletal remains recovered from the upper layers of the Neolithic Nagsabaran site, part of the Lal-lo and Gattaran Shell Middens (~2200 BCE to 400 CE) of northern Luzon. Most of the remains consisted of skull fragments, almost all of which have cut marks indicating they were butchered. The remains are associated with red slipped pottery, spindle whorls, stone adzes, and jade bracelets; which have strong affinities to similar artifacts from Neolithic Austronesian people, Austronesian archeological sites in Taiwan. Based on the radiocarbon date of the layer in which the oldest fragments were found, water buffaloes were first introduced to the Philippines by at least 500 BCE.

''Bos javanicus domesticus'' (Bali cattle)

Bali cattle were domesticated in Bali from the wild banteng around 3500 BCE.

''Canis lupus familiaris'' (dog)

Dogs were primarily valued for their social functions in various Austronesian cultures, acting as companions and pets. They were also trained to be hunting or guard dogs. Ornaments made from dog fur, teeth, and bones are found in archaeological sites throughout Austronesia. These could be traded as commodities, along with dog puppy, pups. Dogs were also sometimes eaten, but this varies by culture, with most groups refusing to eat dogs, while in others they were apparently a main food source.

The origins of the dog (''Canis lupus familiaris'') population in Island Southeast Asia, Australia, and New Guinea are contentious, with various authors proposing origins from either Mainland Southeast Asia, Taiwan, or both at different times. These introduction events have been linked to the origin of the Australian dingoes and the New Guinea singing dogs, both of which are clearly descended from domesticated dogs. The specifics of which population they are derived from, who introduced them, and whether they come from a common ancestor, however, still do not have a consensus.

Regardless, most authors agree that there were at least two introduction events. One arriving with Paleolithic maritime hunter-gatherers by at least 10,000 to 5,000 BP, and another arriving with later Neolithic migrations of farming and trading cultures (including those of Austronesians) by at least 5,000 BP. The Neolithic dogs are differentiated from previous populations in having the ability to digest starch, indicating that they accompanied humans that cultivated cereal crops.

The Neolithic introductions are believed to have partially replaced the original introductions and became the ancestors of the modern village dogs of Southeast Asia. Unlike the first wave, they have adaptations that enable them to digest starch, indicating that they accompanied cultivators of cereal crops.

The oldest archaeological remains of dogs in Island Southeast Asia and Oceania is a dog burial in Timor and dingo remains in Australia, both of which are dated to around 3,500 BP. The former are believed to have been part of the second wave and the latter from the first wave.

From Island Southeast Asia, they were carried by Austronesian voyagers into Near Oceania. Dogs, however, were rare in Lapita culture archaeological sites. Some authors have suggested that Austronesian dogs were "lost" during the early colonization of Near Oceania, purportedly because they were less useful in small island environments. This is said to be the reason for the discontinuity for the terms for "dog" in languages in Southeast Asia, New Guinea, Island Melanesia, and the Pacific Islands. The dog remains in Lapita therefore may have been from individual dogs and dog ornaments acquired from traders from Southeast Asia or more likely from neighboring non-Lapita cultures in New Guinea, where dogs were widely present. But this remains a hypothesis. Nevertheless, dogs were subsequently carried eastward into Polynesia by post-Lapita Austronesian migrations, reaching as far as Hawaii and Aotearoa. Genetic studies have shown that Polynesian dogs are apparently descended from the first wave of dog introductions and are not related to the dogs originating from Taiwan and the Philippines, though this may be an artifact of a founder effect.

On certain Pacific islands, settlers did not bring dogs, or the dogs died out after original settlement, notably: the Mariana Islands, Palau, Marshall Islands, Gilbert Islands, New Caledonia, Vanuatu, Tonga, Marquesas, Mangaia in the Cook Islands, Rapa Iti in French Polynesia, Easter Island, Chatham Islands, and Pitcairn Island (settled by the Mutiny on the Bounty, ''Bounty'' mutineers, who killed off their dogs in order to escape discovery by passing ships).

Dogs were not introduced to Madagascar by Austronesians. A genetic study by Ardalan ''et al.'' (2015) revealed that the dog population in Madagascar were all derived solely from African dog populations and did not come from Southeast Asian dog populations. This aberrant origin is also reflected in the Malagasy languages, where the terms for "dog" originate entirely from African Bantu languages. Given the inferred importance of dogs to Austronesian voyagers, the authors proposed that the Austronesian settlers in Madagascar may have initially brought dogs, but they either died or were used as food sources during the journey. Another possibility is that the limited initial number of Austronesian dogs may have simply resulted in their genes getting swamped by the influx of a far larger population of dogs from Africa.

''Gallus gallus'' (chicken)

Junglefowl were one of the three main animals (along with domesticated pigs and dogs) carried by early Austronesian peoples from Island Southeast Asia in their voyages to the islands of Oceania.

''Sus scrofa domesticus'' (pig)

Domestic pig, Pigs were one of the three main animals (along with domesticated chickens and dogs) carried by early Austronesian peoples from Island Southeast Asia in their voyages to the islands of Oceania.

Rodentia (rodents)

The following rodent species are common in mainland Southeast Asia, but are restricted to areas of wet rice cultivation in western Indonesia ( Sumatra and Java).Groves, Colin P. 2006

''Mus caroli''

''Mus cervicolor''

''Rattus argentiventer''

''Bandicota bengalensis''

The following two rodents are native to South Asia and also present in western Indonesian rice fields, so their presence in Island Southeast Asia cannot easily be explained by Austronesian expansions, but perhaps instead by the Indian Ocean trade.

''Mus terricolor'' (also known as ''Mus dunni'')

Indigenous to northwestern India

''Rattus nitidus'' (indigenous to Nepal)

Polynesian rat (''Rattus exulans'')

This rat originated on the island of Flores in Indonesia. Polynesians accidentally or deliberately introduced it to the islands they settled. This rat has been implicated in many of the extinctions of native birds and insects in the Pacific; these species had evolved in the absence of mammals and could not cope with predation by the rat.
