Anderson discovered plants with the same peculiar fruits at Gunung Gaharu and Telok Sabang. These plants differ from the typical variety in being taller, possessing larger leaves and a secondarily branched inflorescence, this difference in size is so marked that I have accorded them varietal rank as var. magna. Anderson reports (pers. comm.) that the plants he collected came from small and local populations. At Telok Sabang this variety was growing in shallow peat - the only species to be recorded from shallow peat. (Kiew R. 1976)/Palmweb.

Comments and Curiosities

This small, clustering palm, native to the ever diminishing rainforests of Borneo in Sarawak, the Malaysian part of the Island, sports a small crown of bright green leaves with broad segments of different widths, held by pretty, reddish brown leafstalks. (RPS.com)
