This solitary palm tree is the smallest of the Seychelles palms (2). The slender stem may grow up to 8 metres high and is ringed with black spines near to the growing shoot (3). Young leaves are an arresting coral-red colour; they reach up to 2.5 metres long and are feather-like at maturity with leaflets on either side of the midrib (2). Both male and female flowers are found on the same tree; they are small and yellow, borne on solitary, metre-long inflorescences (2). Rounded fruits that may be up to 6 cm long develop; these ripen to a deep red colour at maturity (2).
The species name of melanochaetes refers to the black spines covering the trunk of this palm; the spines are believed to have evolved as a defence against giant tortoises, the only natural large herbivores in the islands. R. melanochaetes normally grows at high altitudes, where tortoises rarely ventured and consequently this species has fewer spines than any other endemic palm (except for the giant coco-de-mer, Lodoicea maldivica) (4).
This small palm species is under threat from habitat destruction in the form of infrastructure development, it is also at risk from the introduction of invasive species (1).
