- The palm family, Arecaceae, is widespread in the Caribbean. Globally there are about 191 genera and 2339 species as reported in 2004 by Carlo Morici. Their distribution is biased toward islands – 36% of genera and 52% of species are found only on islands, while 32% of genera and 6% of species are found only on continents. Sixty-two percent of monotypic genera are found only on islands. Phytogeographically, the Caribbean region is often considered to include the coastal plains of the United States (including south Florida), Mexico (especially the Yucatan), Belize, Colombia and Venezuela. Most species either have a wide distribution which includes part of the Caribbean, or are endemic to the Greater Antilles. Of the islands in the Caribbean, Cuba has the most species of palm, followed by Hispaniola. The Windward and Leeward Islands have the fewest. The palm flora of Trinidad and Tobago consists primarily of species with a South American distribution. Three genera of palm are endemic to the Greater Antilles: Calyptronoma, Hemithrinax and Zombia. Although nearly ubiquitous in the region, the coconut (Cocos nucifera) is not native to the Caribbean. The Caribbean species in the genus Copernicia are all Greater Antillean endemics; two species are restricted to Hispaniola, while the others are restricted to Cuba. (en)
