Koa (Burkina)
''Acacia koa'' or commonly known as koa is a species of flowering tree in the family Fabaceae. It is endemic to the Hawaiian Islands, where it is the second most common tree. The highest populations are on Hawaii, Maui and Oahu. Name The name ''koa'' in the Hawaiian language ultimately comes from Proto-Austronesian *''teRas'' meaning "core" or " ironwood"; many names referring to certain ironwood or heartwood species in Southeast Asia and Oceania such as '' Vitex parviflora'' (''tugás'' in Cebuano), '' Eusideroxylon zwageri'' (''togas'' in Tombonuwo), and '' Intsia bijuga'' (''dort'' in Palauan) descend from this root. ''Koa'' also means brave, bold, fearless, or warrior. Description Koa is a large tree, typically attaining a height of and a spread of . In deep volcanic ash, a koa tree can reach a height of , a circumference of , and a spread of . It is one of the fastest-growing Hawaiian trees, capable of reaching in five years on a good site.

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

Proto-Austronesian Language
Proto-Austronesian (commonly abbreviated as PAN or PAn) is a proto-language. It is the reconstructed ancestor of the Austronesian languages, one of the world's major language families. Proto-Austronesian is assumed to have begun to diversify 3,500–4,000 BCE on Taiwan. Lower-level reconstructions have also been made, and include Proto-Malayo-Polynesian, Proto-Oceanic, and Proto-Polynesian. Recently, linguists such as Malcolm Ross and Andrew Pawley have built large lexicons for Proto-Oceanic and Proto-Polynesian. Phonology Proto-Austronesian is reconstructed by constructing sets of correspondences among consonants in the various Austronesian languages, according to the comparative method. Although in theory the result should be unambiguous, in practice given the large number of languages there are numerous disagreements, with various scholars differing significantly on the number and nature of the phonemes in Proto-Austronesian. In the past, some disagreements concerned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...

Leaflet (botany)
A leaflet (occasionally called foliole) in botany is a leaf-like part of a compound leaf. Though it resembles an entire leaf, a leaflet is not borne on a main plant stem or branch, as a leaf is, but rather on a leaf, petiole or a branch of the leaf. Compound leaves are common in many plant families and they differ widely in morphology (biology), morphology. The two main classes of compound leaf morphology are Leaf shape, palmate and pinnate. For example, a ''Cannabis, hemp'' plant has palmate compound leaves, whereas some species of ''Acacia sensu lato, Acacia'' have pinnate leaves. The ultimate free division (or leaflet) of a compound leaf, or a pinnate subdivision of a multipinnate leaf is called a pinnule or pinnula.

Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Hōlualoa, Hawai'i
Holualoa ( haw, Hōlualoa) is a census-designated place (CDP) in Hawaii County, Hawaii, United States. The population was 8,538 at the 2010 census, up from 6,107 at the 2000 census. Holualoa's boundaries were altered significantly for the 2020 census. The western portion of the CDP near the coast became part of the neighboring Kailua-Kona CDP, while the eastern portion of Kailua-Kona became part of Holualua. This reduced Holualoa's population to 2,994. Geography Holualoa is located on the west side of the island of Hawaii at . It is bordered by Kailua to the north, Honalo and Kahaluu-Keauhou to the south, and the Pacific Ocean to the west. Hawaii Route 11 is the main highway through the community, running north–south, and Hawaii Route 180 runs parallel to it farther inland.

Volcanic Ash
Volcanic ash consists of fragments of rock, mineral crystals, and volcanic glass, created during volcano, volcanic eruptions and measuring less than 2 mm (0.079 inches) in diameter. The term volcanic ash is also often loosely used to refer to all explosive eruption products (correctly referred to as ''tephra''), including particles larger than 2 mm. Volcanic ash is formed during explosive volcanic eruptions when dissolved gases in magma expand and escape violently into the atmosphere. The force of the gases shatters the magma and propels it into the atmosphere where it solidifies into fragments of volcanic rock and glass. Ash is also produced when magma comes into contact with water during phreatomagmatic eruptions, causing the water to explosively flash to steam leading to shattering of magma. Once in the air, ash is transported by wind up to thousands of kilometres away. Due to its wide dispersal, ash can have a number of impacts on society, including animal a ...

Acacia Koa Trees
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palauan Language
Palauan () is a Malayo-Polynesian language native to the Republic of Palau, where it is one of the two official languages, alongside English. It is widely used in day-to-day life in the country. Palauan is not closely related to other Malayo-Polynesian languages and its exact classification within the branch is unclear. Classification It is a member of the Austronesian family of languages, and is one of only two indigenous languages in Micronesia that are not part of the Oceanic branch of that family, the other being Chamorro (see , , , and ). Roger Blench (2015) argues that based on evidence from fish names, Palauan had early contact with Oceanic languages either directly or indirectly via the Yapese language. These include fish names for the sea eel, yellowfin tuna (''Thunnus albacares''), left-eye flounder (''Bothus mancus''), triggerfish, sailfish, barracuda (''Sphyraena barracuda''), damsel fish (''Abudefduf'' sp.), squirrelfish (''Holocentrus'' spp.), unicorn fish ('' ...

Intsia Bijuga
''Intsia bijuga'', commonly known as Borneo teak, Johnstone River teak, Kwila, Moluccan ironwood, Pacific teak, scrub mahogany and vesi, is a species of flowering tree in the family Fabaceae, native to the Indo-Pacific. It ranges from Tanzania and Madagascar east through India and Queensland, Australia, Papua New Guinea to the Pacific islands of Fiji and Samoa.It grows to around 50 metres (160 feet) tall with a highly buttressed trunk. It inhabits mangrove forests. ''Intsia bijuga'' differ from ''Intsia palembanica'' in the number of leaflets that make up their compound leaves. The tree has a variety of common names including ipil and kwila. Uses The bark and leaves of the ipil are used in traditional medicines. The tree's timber, called ''kwila'', is a very durable and termite-resistant wood, making it a highly valued material for flooring and other uses. The wood can also be used to extract a dye. The tree can contain a "gold" fleck that runs through the grain, considered to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
