Thrinax

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.

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]

gollark: You couldn't necessarily see that in any case.
gollark: If stuff does magically run itself, I don't know *how* you would observe that.
gollark: CGoL can simulate itself, that doesn't mean it runs independently of a computer running it.
gollark: Stuff is seemingly not magically self-computing. At least, I haven't seen algorithms somehow run themselves.
gollark: That is a good question. "I think therefore I am" and all, but that really only implies that in some form "I" am running on some kind of processing hardware which can do consciousness, whether it is my foolish mortal brain in a universe with quarks and everything or a simulation of that on, I don't know, some kind of massive cellular automaton.
