Pandanus Dubius
''Pandanus dubius'', commonly known as bakong or knob-fruited screwpine, is a species of ''Pandanus'' (screwpine) native to Island Southeast Asia, New Guinea, and the Western Pacific islands (Melanesia and Micronesia), and possibly also to the Andaman and Nicobar Islands. Taxonomy ''Pandanus dubius'' was first described by the German botanist Kurt Polycarp Joachim Sprengel in 1826. It is classified in the subgenus ''Rykia'', section ''Hombronia''. Description Bakong grows to about high with numerous thick prop roots and aerial roots. The leaves are lanceolate in shape with shallow serrations along the edges. The leaves are around long and wide, and dark green in color. Bakong are dioecious, having separate male and female plants. The fruits are globular in shape and are around in diameter. Habitat Bakong typically grows on beaches, rocky areas, and limestone outcrops in coastal ecosystems. Uses Like other species of pandanus, the leaves of bakong are commonly harvested fo ...

Kurt Polycarp Joachim Sprengel
Kurt Polycarp Joachim Sprengel (3 August 1766 – 15 March 1833) was a German botanist and physician who published an influential multivolume history of medicine, ''Versuch einer pragmatischen Geschichte der Arzneikunde'' (1792–99 in four volumes with later editions running to five) and several other medical reference works. Biography Sprengel was born at Boldekow in Pomerania, and he is considered of German nationality. His father, a clergyman, provided him with a thorough education of wide scope; as boy he distinguished himself as a linguist, in Latin and Greek, and also Arabic; his uncle, Christian Konrad Sprengel (1750–1816), is remembered for his studies in the fertilization of flowers by insects – a subject in which he reached conclusions many years ahead of his time. Spreng. appeared as an author at the age of fourteen, publishing a small work called '' Anleitung zur Botanik für Frauenzimmer'' ("guide to botany for women") in 1780. In 1784 he began to study the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Malesia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domesticated Plants And Animals Of Austronesia
One of the major Early human migrations, human migration events was the Maritime history, maritime Austronesian expansion, settlement of Austronesia, the islands of the Indo-Pacific by the Austronesian peoples, believed to have started from at least 5,500 to 4,000 Before Present, BP (3500 to 2000 BCE). These migrations were accompanied by a set of domesticated, semi-domesticated, and commensal plants and animals transported via outrigger canoe, 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 domesticated plants, crops and domesticated animals, animals believed to have originated from the Hemudu culture, Hemudu and Majiabang cultures in the hypothetical pre-Austronesian homelands in mainland China, as well as other plants and a ...

Pandanus Utilis
''Pandanus utilis'', the common screwpine is, despite its name, a monocot and not a pine. It is native to Madagascar and naturalised in Mauritius and the Seychelles. Description The trunk features aerial prop roots. The leaves are linear and spiny, with a spiral arrangement on the tree. The leaves are also dried out and rolled, and used to make mats in Kerala, India; and Hawaii. Care must be taken when handling the leaves because of their sharp spines. The fruit of ''Pandanus utilis'' is edible, although not flavorful to humans and must be cooked prior to consumption. It attracts mammals such as, in North America, squirrels. Introduction Within the family Pandanaceae, the genus ''Pandanus'' is thought to compose the largest group of plants.M. H. Zimmerman, et al., "Vascular Construction and Development in the Stems of Certain Pandanaceae," ''Botanical Journal of the Linnean Society'' 68:1 (January 1974): 21-41 It is estimated that there are somewhere between 500 and 1,000 spec ...

Pandanus Amaryllifolius
''Pandanus amaryllifolius'' is a tropical plant in the ''Pandanus'' (screwpine) genus, which is commonly known as pandan (; ). It has fragrant leaves which are used widely for flavouring in the cuisines of Southeast Asia and South Asia. Occurrence and habitat ''Pandanus amaryllifolius'' is a true cultigen, and is believed to have been domesticated in ancient times. It is sterile and can only reproduce vegetatively through suckers or cuttings. It was first described from specimens from the Maluku Islands, and the rare presence of male flowers in these specimens may indicate that it is the origin of the species. However, as no other wild specimens have been found, this is still conjecture. The plant is grown widely throughout Southeast Asia and South Asia. Botanical features The characteristic aroma of pandan is caused by the aroma compound 2-acetyl-1-pyrroline, found in the lower epidermal papillae; the compound gives white bread, jasmine rice, and basmati rice (as well as brea ...

Rota Island
Rota (Chamorro: Luta), also known as the "Friendly Island", is the southernmost island of the United States Commonwealth of the Northern Mariana Islands (CNMI) and the second southernmost of the Marianas Archipelago. In early Spanish records it is called "Zarpana"; the name Rota may have come from the Spaniards possibly naming the island after the municipality of Rota, Spain. It lies approximately north-northeast of the United States territory of Guam. Sinapalo village is the largest and most populated, followed by Songsong village (Songsong). Rota also functions as one of the four municipalities of the CNMI. History In 1521, the first European to see Rota was the lookout on Ferdinand Magellan's ship ''Victoria'', Lope Navarro. However, Magellan's armada of three ships did not stop until they reached Guam, so the first European to arrive in Rota (in 1524), was the Spanish navigator Juan Sebastián Elcano, who annexed it together with the rest of the Mariana Islands on behalf o ...

Solomon Islands
Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands. The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called ''"the Solomons"'' by those who later receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bismarck Archipelago
The Bismarck Archipelago (, ) is a group of islands off the northeastern coast of New Guinea in the western Pacific Ocean and is part of the Islands Region of Papua New Guinea. Its area is about 50,000 square km. History The first inhabitants of the archipelago arrived around 30–40,000 years ago. They may have traveled from New Guinea, by boat across the Bismarck Sea or via a temporary land bridge, created by an uplift in the Earth's Crust (geology), crust. Later arrivals included the Lapita people. The first European to visit these islands was Dutch explorer Willem Schouten in 1616. The islands remained unsettled by western Europeans until they were annexed as part of the German protectorate of German New Guinea in 1884. The area was named in honour of the Chancellor of Germany (German Reich), Chancellor Otto von Bismarck.
