Key to the species of Coccothrinax in Hispaniola 1. Leaf segments pendulous at the apices, giving a three-dimensional appearance to the leaf; leaf segment hairs with a conspicuous elliptic center; Haiti (Tortuga island) and Dominican Republic (Morro de Monte Cristi)............................................... C. argentata - Leaf segments not pendulous at the apices; leaf segment hairs without conspicuous centers..........................................................2. 2. Leaf sheath fibers closely woven, forming persistent, triangular ligules at the apices; throughout Hispaniola............... C. argentea - Leaf sheath fibers not forming persistent, triangular ligules at the apices........................................................................................3. 3. Leaf sheath fibers thin (usually 1 mm diameter), woody, loosely woven, ± joined or briefly free at the apices, or the inner and outer layer combining at the apices to form erect, spine-like fibers, or stout (usually 0.3–0.5 mm diameter), loosely woven and forming a loose, hexagonal mesh, initially forming ligules at the apices.........................................................................................5. 4. Stems 4.4–15.0 cm diameter, not swollen; at 10–26 m elevation in southeastern Dominican Republic (La Altagracia, San Pedro de Macoris)....................................................................................................................................................................... C. barbadensis - Stems 11.0–50.0 cm diameter, sometimes swollen; throughout Hispaniola......................................................................... C. spissa 5. Fruits 8.3–16.4 mm long; at higher elevations..................................................................................................................................6. - Fruits 3.9–7.9 mm long; at lower elevations.....................................................................................................................................7. 6. Palmans 8.3(3.5–15.3) cm long, relatively short, with the adaxial veins prominent and terminating in a slight raised ridge and distinct pulvinus; Dominican Republic (Sierra Martín García and Sierra de Baoruco) and Haiti (Massif de la Hotte and probably Massif de la Selle).............................................................................................................................................................

Fruit surfaces densely muricate.........................................................................................................................................................8. - Fruit surfaces smooth or sometimes with projecting fibers.............................................................................................................10. 8. Leaf sheath fibers combining at the apices to form erect, spine-like fibers; southeastern Haiti (Sud-Est) and southwestern Dominican Republic (Barahona, Pedernales)....................................................................................................................................... C. ekmanii - Leaf sheath fibers ± joined or briefly free at the apices....................................................................................................................9. 9. Leaf blades orbicular; Dominican Republic (Azua)........................................................................................................ C. boschiana - Leaf blades wedge-shaped; northeastern Dominican Republic (Samaná).................................................................... C. samanensis 10. Inflorescences erect, at least initially, amongst or above the leaves; north-central Dominican Republic (Espaillat).... C. bonettiana - Inflorescences curving, arching, or pendulous amongst the leaves.................................................................................................11. 11. Leaf blades orbicular.......................................................................................................................................................................12. - Leaf blades wedge-shaped...............................................................................................................................................................14. 12. Leaf segments without indumentum abaxially; southern Haiti (Department Sud-Est)..................................................... C. concolor - Leaf segments densely indumentose abaxially................................................................................................................................13. 13. Fruits 3.8–4.7 mm diameter; seed surfaces lobed, the lobes running from base of seeds approximately to equator; northeastern Dominican Republic (El Seibo, Hato Mayor)....................................................................................................... C. montgomeryana - Fruits 7.1–7.2 mm diameter; seed surfaces deeply lobed, the lobes running from base of seeds almost to apices; northwestern Haiti (Nord-Ouest)........................................................................................................................................................................
