Coccothrinax

'' showing fibrous leaf sheaths Coccothrinax is a genus of small to medium-sized, fan palms with relatively slender stems and 8 to 22 palmate leaves. 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. The undersides of the leaflets are often silvery-grey; this is reflected in the common name "silver palm", which is given to many species of Coccothrinax. The base of the petiole is not split longitudinally. The absence of this trait is a distinguishing character that separates Coccothrinax from Thrinax. Coccothrinax species bear branched inflorescences that are located among the leaves. The bisexual flowers, which are borne on short stalks, have between 6 and 13 stamens and a single carpel. The fruit are small, single-seeded, and range in colour from purple-red to purple-black, to brown. The seeds are deeply grooved "and resemble a brain". ==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; while the former is now recognised as part of Coccothrinax, the latter remains in Thrinax. The generic epithet combines "coccus", the Latin word for berry, with Thrinax. Coccothrinax is placed in the tribe Cryosophileae. ==Distribution==

Coccothrinax is a primarily Caribbean genus—it is found throughout the insular Caribbean, and in adjacent areas of Mexico and Florida. Coccothrinax barbadensis ranges through the Lesser Antilles to Trinidad and Tobago and the Netherlands Antilles. The remaining species have narrower distributions; many are known from single populations in Cuba or Hispaniola. ==Botanic gardens==

Large collections are grown in Fairchild Tropical Botanic Garden (more than 250 plants, more than 23 species), in Miami, Florida, Jardín Botánico Nacional (15 species) in Havana, Cuba, and Palmetum of Santa Cruz de Tenerife (more than 1,000 Thrinax and Coccothrinax plants), in the Canary Islands, Spain. == References ==
