Common Names:

Swamp Cabbage,
Morass Royal,
Royal Palm

Distribution & Habitat:

Restricted to western parishes of Jamaica, in small colonies or as scattered individuals, in morass and in poorly drained lowlands, from sea level to 150 metres.

Description:

A tall, solitary palm to 15 metres (50 feet) or more tall, with a smooth grey trunk irregularly enlarged below, more slender above, and banded with leaf-scars. Leaves are pinnate 4-6 metres (12-18 feet) long, with slightly plumose leaflets, and a green crownshaft about 1.5 metres (4.5 feet) long. Fruit usually one seeded, drupe-like, pear-shaped, with the neck curved to one side, about 15 mm (2/3 inch) long, greenish-yellow to purple, with a small seed.

It is very similar in appearance to R. altissima, and very difficult to distinguish between the two. The easiest method in the field is locality, R. princeps is a bog and swamp species, while R. altissima is found in uplands and premontane elevations.

Cultivation:

Likes a sunny, moist position.
