''Cossinia'' is a genus of four species known to science, of rainforest trees, constituting part of the plant family Sapindaceae.〔 The four species have an apparently ancient Gondwanan origin and present day distribution, consisting of an endemic, distinct, species in each of the southern hemisphere regions of the Mascarene Islands, Australia, New Caledonia and Fiji.〔〔〔〔〔 They grow naturally in rainforests, including seasonally drought–prone rainforests, and associated non–fire–adapted vegetation types. ''Cossinia trifoliata'' trees, endemic to New Caledonia, have become vulnerable to global extinction according to the International Union for Conservation of Nature (IUCN)'s 1998 assessment.〔 ''Cossinia australiana'' trees, known as growing naturally only (endemic) in restricted habitat areas of central-eastern and south-eastern Queensland, Australia, have the official national and Queensland state governments' "endangered" conservation status.〔〔 Within their known endemic region the trees grow naturally in habitats which have historically had their native vegetation extensively destroyed and have been further threatened.〔〔〔〔 ==Naming and classification== The genus was first described in 1786 by Jean-Baptiste Lamarck in ''Encyclopédie Méthodique: Botanique''. The publication includes descriptions of the species ''Cossinia pinnata'' and ''C. triphylla'', named earlier by Philibert Commerson.〔〔〔 In 1982 Australian botanist Sally T. Reynolds formally described the new species name ''Cossinia australiana'', recognised that ''C. triphylla'' is a synonym of ''C. pinnata'' and updated Ludwig A. T. Radlkofer's species identification key to include all four currently accepted species.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cossinia」の詳細全文を読む スポンサード リンク
