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.
