Thrinax is a genus in the palm family, native to the wider Caribbean. It is closely related to the genera Coccothrinax, Hemithrinax and Zombia.[3] 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

| Simplified phylogeny of the tribe Cryosophileae (except Trithrinax) based on the nuclear genes PKR and RPB2.[4] |
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[5] 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.[1] 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.[6]
