India (North-east), Bangladesh, China (South Yunnan) and Laos (Central). Also in South-east China (Pei et al. 1991) (Evans, T., Sengdala, K., Thammavong, B., Viengkham, O.V. & Dransfield, J. 2002: A Synopsis of the Rattans (Arecaceae: Calamoideae) of Laos and Neighbouring Parts of Indochina)A

Biology And Ecology

  • Evergreen forest at 300 - 750 m in Laos, up to 850 m in South Yunnan. (Evans, T., Sengdala, K., Thammavong, B., Viengkham, O.V. & Dransfield, J. 2002: A Synopsis of the Rattans (Arecaceae: Calamoideae) of Laos and Neighbouring Parts of Indochina)A

Conservation

  • Unknown, but likely to be of low concern due to its wide range and clustering habit, which allows it to tolerate a moderate level of harvesting. However, Renuka (1999) notes that the Indian populations have declined considerably in recent years. (Evans, T., Sengdala, K., Thammavong, B., Viengkham, O.V. & Dransfield, J. 2002: A Synopsis of the Rattans (Arecaceae: Calamoideae) of Laos and Neighbouring Parts of Indochina)A

Common Name

  • wai hom, wai soum, wai tairtair (Lao Loum). (Evans, T., Sengdala, K., Thammavong, B., Viengkham, O.V. & Dransfield, J. 2002: A Synopsis of the Rattans (Arecaceae: Calamoideae) of Laos and Neighbouring Parts of Indochina)A

Uses

  • The cane is of high quality and widely traded. The shoot is edible. (Evans, T., Sengdala, K., Thammavong, B., Viengkham, O.V. & Dransfield, J. 2002: A Synopsis of the Rattans (Arecaceae: Calamoideae) of Laos and Neighbouring Parts of Indochina)A
