Calyptronoma occidentalis is a pinnately compound leaved palm species which is endemic to Jamaica.[1] C. occidentalis stems grow singly and reach heights of 7–12 m, with stems 17–20 cm in diameter.[1] It grows in waterlogged areas near the banks of streams, up to an elevation of 800 m above sea level.[1]
The species was first described by Swedish botanist Olof Swartz in 1797 in his Flora Indiae Occidentalis.
