''Thrinax'' is a genus in the palm family, native to the wider Caribbean. It is closely related to the genera ''Coccothrinax'', ''Hemithrinax'' and ''Zombia''. Flowers are small and bisexual, and are borne on small stalks. ''Thrinax'' consists of four species. Three of them are single-island endemics - ''Thrinax ekmaniana'' is exclusively endemic to hills Mogotes de Jumagua, Cuba while ''Thrinax excelsa'' and ''Thrinax parviflora'' are endemic to Jamaica. The fourth species, ''Thrinax radiata'', is more widespread - it is present in the Greater Antilles, the Bahamas, south Florida, Mexico and Central America. ==Taxonomy== |2= }} |2=''Itaya'' }} |2=''Chelyocarpus'' }} |align= left }} In the first edition of ''Genera Palmarum'' (1987), Natalie Uhl and John Dransfield placed the genus ''Thrinax'' in the subfamily Coryphoideae, the tribe Corypheae and the subtribe Thrinacinae Subsequent phylogenetic analysis showed that the Old World and New World members of the Thrinacinae are not closely related. As a consequence of this, ''Thrinax'' and related genera have been placed in their own tribe, Cryosophileae.〔 In 2008, ''Leucothrinax morrisii'' (formerly ''T. morrisii'') was split from ''Thrinax'' after phylogenetic studies showed that its inclusion in ''Thrinax'' would render that genus paraphyletic. 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「Thrinax」の詳細全文を読む スポンサード リンク
