Leucothrinax morrisii, the Key thatch palm, is a small palm which is native to the Greater Antilles, northern Lesser Antilles, The Bahamas and the Florida Keys. Until 2008 it was known as Thrinax morrisii. It was split from the genus Thrinax after phylogenetic studies showed that its inclusion in Thrinax would render that genus paraphyletic.
Description
Leucothrinax morrisii is a palmate-leaved palm with solitary stems 1–11 metres (3–36 ft) tall and 5–35 centimetres (2–14 in) in diameter.[3]
Taxonomy
Leucothrinax is a monotypic genus - it includes only one species, L. morrisii. The species was originally described German botanist Hermann Wendland, who places it in the genus Thrinax.
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[4] using Harold E. Moore's 1973 classification of the palm family.[5] Subsequent phylogenetic analysis showed that the Old World and New World members of the Thrinacinae were not closely related. As a consequence of this, Thrinax and related genera were places in their own tribe, Cryosophileae[1] A study of the phylogenetic relationships among Caribbean palms showed that the species then known as Thrinax morrisii was most closely related to Coccothrinax, Hemithrinax and Zombia, with the remainder of the genus Thinax being a sister group to this clade.[6] Since the continued inclusion of this genus would render Thrinax paraphyletic, it was split off into a new genus, Leucothrinax.[7]
Common names
Leucothrinax morrisii is known as the "Key thatch palm" or the "brittle thatch palm" in the United States.[citation needed] In Anguilla it is called the "broom palm", "buffalo-top" in The Bahamas, miraguano in Cuba and palma de escoba in Puerto Rico.[3]
Distribution
Leucothrinax morrisii is native to the Florida Keys, Bahamas, Cuba, Haiti, Puerto Rico,[2] Navassa Island[8], Anguilla and Barbuda.[3]
It is found in dry, deciduous forests and coastal areas.[3]
Uses
Stems of the plant are used for poles and the leaves are used for thatch and weaving.[3]
