Thrinax is a genus in the palm family, native to the Caribbean. It is closely related to the genera Coccothrinax, Hemithrinax and Zombia.^[2] Flowers are small, bisexual and are borne on small stalks.

Taxonomy

Cryosophileae

Thrinax

Simplified phylogeny of the Cryosophileae based on four nuclear genes and the matK plastid gene.^[3]

In the first edition of Genera Palmarum (1987), Natalie Uhl and John Dransfield placed the genus Thrinax in subfamily Coryphoideae, tribe Corypheae and subtribe Thrinacinae.^[4] Subsequent phylogenetic analyses showed that the Old World and New World members of Thrinacinae are not closely related and as a consequence, Thrinax and related genera were transferred into their own tribe, Cryosophileae.^[5] 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]

Thrinax consists of three species.
