Description: Roystonea regia is a large palm which reaches a height of 20–30 metres (66–98 ft) tall,[6] (with heights up to 34.5 m (113 ft) reported)[7] and a stem diameter of about 47 centimetres (19 in).[6] (K. F. Connor reports a maximum stem diameter of 61 cm (24 in).)[7] The trunk is stout, very smooth and grey-white in colour with a characteristic bulge below a distinctive green crownshaft.[8] Trees have about 15 leaves which can be up to 4 m (13 ft) long.[6] The flowers are white with pinkish anthers.[8] The fruit are spheroid to ellipsoid in shape, 8.9–15 millimetres (0.35–0.59 in) long and 7–10.9 mm (0.28–0.43 in) wide.[6] They are green when immature, turning red and eventually purplish-black as they mature.[8]

Habitat: Cultivated

Distribution: Native to native to Mexico, parts of Central America and the Caribbean, and southern Florida.

Uses:  Ornamental palm, The seed is used as a source of oil and for livestock feed. Leaves are used for thatching and the wood for construction.[7] The roots are used as a diuretic,[37] and for that reason they are added to tifey, a Haitian drink, by Cubans of Haitian origin.[38] They are also used as a treatment for diabetes.[37] Fibres extracted from the leaf sheath of R. regia have been found to be comparable with sisal and banana fibres, but lower in density, making it a potentially useful source for the use in lightweight composite materials.
