This unusual palm tree was first discovered by the Royal Botanic Gardens, Kew in 1991 and was distinctive enough to be placed in its own genus. The leaves are fan-shaped and the genus name Satranala actually means 'fan palm of the forest' in Malagasy. This species is a solitary, dioecious tree with a hard, straight trunk; Height: 8 - 15 m. Stem diameter: 15 - 18 cm., supporting around 20 - 24 fan-shaped leaves. The most exciting and intriguing feature of this palm however, are the seeds, the inner coat of which carries ridges and flanges that are unique amongst palms in the region, whose seeds are generally smooth. These seeds are so unique in fact, that they resemble (albeit faintly) only a few other palm species on the far-off island of New Guinea. The species name decussilvae is Latin for 'jewel of the forest'. Classified as Endangered (EN - D) on the IUCN Red List 1997.

Endemic to Madagascar, this palm is found at a single site within the Mananara Biosphere Reserve, in the northeast of the island, and in a few scattered populations in the Masoala National Park. Satranala decussilvae occupies wet rainforest on shallow soils within steep-sided valleys, or low ridge tops. Found between 250 - 285 metres above sea level. Vast tracts of Malagasy forests have been cleared, predominantly by slash-and-burn agriculture, and much of the former habitat has been lost. There seems very little, if any, effective dispersal of the palm at the present day and this makes it particularly vulnerable.
