Coccothrinax is a genus of palms in the Arecaceae family. There are more than 50 species described in the genus, plus many synonyms and sub-species. A new species (Coccothrinax torrida) has been described as recently as 2006. Many of the Coccothrinax have silver or thatch, or both, in their English common names. In Spanish - speaking countries, guano is a common name applied to Coccothrinax species. The species are native throughout the Caribbean, the Bahamas, extreme southern Florida and southeastern Mexico, but most of the species are known only from Cuba.[2][3][4]

Description

Coccothrinax is a genus of small to medium-sized, fan palms with relatively slender stems[5] and 8 to 22 palmate leaves.[6] The stems are initially covered by fibrous leaf sheaths. These break down into a network of fibres or spines, eventually leaving a bare trunk covered with leaf scars.[5]

Taxonomy

The genus Coccothrinax was first described by American botanist Charles Sprague Sargent in 1899. He split the genus away from Thrinax based on characteristics of the fruit and seeds. The genus was based on Sargent's description of C. jucunda (now C. argentata) and C. garberi (also synonymised with C. argentata). He also assigned Thrinax argentea and T. radiata to the genus;[7] although the former is now known as recognised as part of Coccothrinax, the latter remains in Thrinax.[8]

Uses

The largest collections[citation needed] are grown in Fairchild Tropical Botanic Garden[2], in Miami, Florida, Jardín Botánico Nacional[3] , in Havana, Cuba and Palmetum of Santa Cruz de Tenerife[4], in the Canary Islands, Spain.

Species

The following species of Coccothrinax are listed as "accepted" names in the World Checklist of Monocotyledons, hosted by the Royal Botanic Gardens, Kew.[9] This list does not include synonyms or sub-species.
