Clustering high-climbing dioecious hapaxanthic rattans with moderate to robust stems. Leaf cirrate, sheaths without knees, ocrea sometimes conspicuous; rachis bearing entire ± regularly arranged concolorous leaflets. Inflorescences produced simultaneously in the axils of the uppermost leaves, male and female superficially similar; primary axis branching to 1 or 2 orders, the branches bearing tubular triangular-tipped bracts subtending clusters of 2–7 flowers. Male flower with tubular calyx with 3 triangular lobes and 3 petals joined at the base; stamens 6, borne on the petals; pistillode minute; female flower with tubular calyx with 3 very short obtuse lobes, and corolla with 3 lobes; staminodes 6 epipetalous; ovary tipped with 3 small divergent stigmas; calyx enlarging considerably and splitting irregularly, persisting to mature fruiting; corolla also persistent. Mature fruit tipped with minute stigmatic remains, covered in many somewhat irregular vertical rows of scales. Seed with thin sarcotesta; endosperm homogeneous. Seedling leaf bifid.
Six or seven sepcies known from Myanmar and Thailand south to Peninsular Malaysia, Sumatra, Billiton and Borneo. Two species in Thailand. A genus of rather coarse clustering rattans normally found in secondary forest or seral facies of primary forest (such as old landslips or the clearings formed by the death or fall of large trees). Generally not used as the cane has a soft pith and poor external appearance. However, the apex of at least one species is eaten in some parts of Borneo
