Sclerotheca is a genus of plants native to various islands in the South Pacific. Nine of the ten known species are French Polynesia, the tenth to Rarotonga in the Cook Islands. [1] [2]
The Marquesas Islands are a group of volcanic islands in French Polynesia, an overseas collectivity of France in the southern Pacific Ocean. Their highest point is the peak of Mount Oave on Ua Pou island, at 1,230 m (4,035 ft) above sea level.
Coprosma is a genus of flowering plants in the family Rubiaceae. It is found in New Zealand, Hawaiian Islands, Borneo, Java, New Guinea, islands of the Pacific Ocean to Australia and the Juan Fernández Islands.
Arthropodium is a genus of herbaceous perennial plants in the subfamily Lomandroideae of the family Asparagaceae. It is native to Australia, New Zealand, New Caledonia and Madagascar.
Sphaeropteris medullaris, synonym Cyathea medullaris, commonly known as mamaku or black tree fern, is a large tree fern up to 20 m tall. It is distributed across the south-west Pacific from Fiji to Pitcairn Island. Its other Māori names include katātā, kōrau, or pītau.
Westringia is a genus of Australian shrubs. As with other members of the mint family their upper petal is divided into two lobes. There are four stamens - the upper two are fertile while the lower two are reduced to staminodes. The leaves are in whorls of 3 or 4.
Cyathea affinis is a variable species of tree fern native to Fiji, Samoa, the Cook Islands, Austral Islands, Tahiti, and the Marquesas Islands. The trunk of this plant is erect and 2–6 m tall. Fronds are bipinnate and 2–3 m in length. The rachis and stipe are pale to brown in colour, or flushed with red towards the pinnule rachis. The stipe is sparsely covered in narrow basal scales, which are pale to dark and have broad fragile edges. Characteristically of this species, the lowest one or two pairs of pinnae may be slightly reduced and occur towards the base of the stipe. Sori are located near the pinnule midvein and are partially or fully covered by indusia, which open towards the pinnule margin.
Weinmannia is a genus of trees and shrubs in the family Cunoniaceae. It is the largest genus of the family with about 150 species. It is also the most widespread genus, occurring in Central and South America including the Caribbean, Madagascar and surrounding islands, Malesia and the islands of the South Pacific. It is absent from mainland Africa and Australia, but some fossils have been attributed to Weinmannia in Australia. Leaves are simple or pinnate, with a margin usually toothed, and interpetiolar stipules. Flowers are bisexual, white, arranged in racemes. The fruit is a capsule opening vertically from the top to the base. Seeds hairy without wings.
Dianella is a genus of about forty species of flowering plants in the monocot family Asphodelaceae and are commonly known as flax lilies. Plants in this genus are tufted herbs with more or less linear leaves and bisexual flowers with three sepals more or less similar to three petals and a superior ovary, the fruit a berry. They occur in Africa, South-east Asia, the Pacific Islands, New Zealand and Australia.
Reynoldsia is an obsolete genus of flowering plants in the ivy family, Araliaceae. In 2003, Kew Gardens published a checklist for Araliaceae, in which eight species were recognized for Reynoldsia: four from Samoa, two from Tahiti, one from the Marquesas, and one from Hawaii. In 2010, a phylogenetic comparison of DNA data showed that Reynoldsia was polyphyletic, consisting of two groups that are not each other's closest relatives. In a companion paper, three of the species were "sunk" into synonymy with others, reducing the number of species to five. All species that were formerly in Reynoldsia are now in ''Polyscias'' subgenus Tetraplasandra, a subgenus of 21 species indigenous to Malesia and Pacific islands.
Lebronnecia is a monotypic genus of flowering plants in the family Malvaceae. The sole species is Lebronnecia kokioides, a very rare flowering shrub.
Oparanthus is a genus of flowering plant in the family Asteraceae, native to the islands of French Polynesia.
Lepinia is a genus of plant in the family Apocynaceae first described as a genus in 1849. It is native to various islands in the Pacific Ocean.
Rauvolfia sachetiae is a species of plant in the family Apocynaceae. It is endemic to the Marquesas Islands in French Polynesia. It is listed as a "Critically endangered" species.
Gahnia is a genus of sedges native to China, Southeast Asia, New Guinea, Australia, New Zealand and a number of Pacific Islands. The common name is due to the toothed margins. It often forms tussocks.
Cyrtosperma is a genus of flowering plants in the family Araceae. The genus went through considerable taxonomic changes in the 1980s, and as a result is now considered to be native only to Southeast Asia and some Pacific islands. Previously, the genus was believed to be widespread from Asia to Africa and South America, but the African and South American species were subsequently moved into separate genera. Cyrtosperma is now known to be most prominent in New Guinea. The genus Cyrtosperma is unique in this regards because it is the only known big genus in Araceae that is known to be found east of Wallace's line.
Astelia is a genus of flowering plants in the recently named family Asteliaceae. They are rhizomatous tufted perennials native to various islands in the Pacific, Indian, and South Atlantic Oceans, as well as to Australia and to the southernmost tip of South America. A significant number of the known species are endemic to New Zealand. The species generally grow in forests, swamps and amongst low alpine vegetation; occasionally they are epiphytic.
Leptecophylla is a genus of flowering plants in the family Ericaceae. The genus is native to southeastern Australia, New Zealand, Papua New Guinea and the Pacific Islands. Some species in this genus were formerly classified within the genera Cyathodes, Lissanthe, Styphelia and Trochocarpa.
Diurideae is a tribe of orchid in the subfamily Orchidoideae. It contains about 40 accepted genera. As of April 2018, its division into subtribes remained unclear.
Apetahia was a genus of plants native to various islands of French Polynesia in the South Pacific now considered to be a synonym of Sclerotheca.
Rauvolfia nukuhivensis is a species of plant in the family Apocynaceae. It is endemic to Nuku Hiva in the Marquesas Islands in French Polynesia.
