''Alectryon'' is a genus of about 30 species of trees and shrubs known to science, constituting part of the plant family Sapindaceae. They grow naturally across Australasia, Papuasia, Melanesia, western Polynesia, east Malesia and Southeast Asia, including across mainland Australia, especially diverse in eastern Queensland and New South Wales, the Torres Strait Islands, New Guinea, the Solomon Islands, New Caledonia, New Zealand, Vanuatu, Fiji, Samoa, Hawaii, Indonesia and the Philippines.〔〔〔〔 They grow in a wide variety of natural habitats, from rainforests, gallery forests and coastal forests to arid savannas and heaths. Mainland Australia, especially the eastern Qld and NSW rainforests and the monsoon tropics, harbours the global centre of ''Alectryon'' species diversity, having 15 species, 12 of them endemic to Australia.〔〔 In the continent of, combined New Guinea including Papua New Guinea and West Papua, Australia and all of their continental islands, including the Torres Strait Islands, known collectively in biogeography as the Sahul continent, lives the even greater diversity and endemism of 21 and 19 species, respectively. ==Conservation== ''Alectryon macrococcus'' scarce remaining small trees across the Hawaiian islands and in both its varieties, have obtained the "critically endangered" species global conservation status of the International Union for Conservation of Nature (IUCN).〔〔 In Australia: * ''A. ramiflorus'' small trees only remain naturally growing (endemic) in a very restricted area of south eastern Qld, thus they have obtained the "endangered" species global conservation status of the IUCN (1998) and 2013 national and state conservation statuses of the Australian and Qld governments.〔〔 * ''A. repandodentatus'' small trees in north-eastern Qld, the Torres Strait Islands and New Guinea have obtained the "vulnerable" species global conservation status of the IUCN (1998), and the Qld state government's 2013 "endangered" species conservation status.〔〔 * ''A. semicinereus'' small trees in eastern Qld have obtained the Qld government "near threatened" species conservation status.〔 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「Alectryon (genus)」の詳細全文を読む スポンサード リンク
