Roystonea lenis is a species of palm which is endemic to Guantánamo Province in eastern Cuba.[2]
Description
Roystonea lenis is a large palm which reaches heights of 20 metres (66 ft). Stems are grey-white and are usually 35–47 centimetres (14–19 in) in diameter. The upper portion of the stem is encircled by leaf sheaths, forming a green portion known as the crownshaft which is normally 2 m (6.6 ft) long. Individuals have about 15 leaves with 0.2–0.7 cm (0.079–0.276 in) petioles and 4–5.8-metre (13–19 ft) rachises; the leaves hang well horizontal. The 1 m (3.3 ft) inflorescences bear white male and female flowers. Fruit are 11.3–14 millimetres (0.44–0.55 in) long and 8.8–11.1 mm (0.35–0.44 in) wide, and black when ripe.[2]
