''Elattostachys'' is a genus of about 21 species of trees known to science, constituting part of the plant family Sapindaceae.〔〔 They grow naturally in the New Guinea, the Moluccas, Sulawesi, Indonesia, Timor, Australia, New Caledonia, Vanuatu, Fiji, Samoa, Niue, Tonga, Palau (Caroline Islands) and the Philippines.〔〔 The known centre of diversity of New Guinea has nine known species recognised by science .〔 In Australia, they grow naturally through the northern half of the eastern coastal zone, northwards from the Newcastle region in New South Wales through eastern Queensland to the northernmost point of Australia Cape York Peninsula.〔〔〔〔〔 One of them ''E. xylocarpa'' has a common name of white tamarind, while another ''E. nervosa'' has a common name of beetroot tree. A few members of the Australian Sapindaceae are called tamarinds, although they have no close relation to the true tamarind, which is a member of the bean family. ==Conservation== At the global scale, several ''Elattostachys'' species have been threatened with extinction, as officially recognised by the International Union for Conservation of Nature (IUCN). Three New Guinea endemic species ''E. aiyurensis'', ''E. goropuensis'' and ''E. rubrofructus'', one Sulawesi endemic species ''E. erythrocarpum'' and one New Caledonia endemic species ''E. dzumacensis'' have been vulnerable to global extinction according to the IUCN's 1998 assessment.〔〔〔〔〔 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「Elattostachys」の詳細全文を読む スポンサード リンク
