Discussion

  • D. serpentina is confined to rather exposed areas of forest on ultrabasic rock in the lowlands - areas such as ridgetops and steep slopes where the light intensity reaching the forest floor is high. In the field the shuttlecock appearance of the whole plant is very distinctive. (J. Dransfield, The Rattans of Sabah. Sabah Forest Records 13.. 1984)A
