Roystonea maisiana is a species of palm which is endemic to the Maisí region of Guantánamo Province in eastern Cuba.

Description

Roystonea maisiana is a large palm which reaches heights of 20 metres (66 ft). Stems are grey-white and are usually 26–40 centimetres (10–16 in), sometimes up to 51 centimetres (20 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 1.5 m (4.9 ft) long. Individuals have about 15 leaves with 4.8-metre (16 ft) rachises; the leaves hang well horizontal. The 0.8–1.1 m (2.6–3.6 ft) inflorescences bear white male and female flowers. Fruit are 10–13.7 millimetres (0.39–0.54 in) long and 7.5–9.5 mm (0.30–0.37 in) wide, and black when ripe.[3]
