Indochinese endemic. Thailand (North-east) and Laos (Central). (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

Discussion

  • The published description did not emphasize the clear differences in female rachillae and fruiting perianth structure between this species and both C. solitarius and C. tetradactylus (see key). Examination of additional material at BM has confirmed that these are valuable, consistent differences. They also suggest that those two species may be more closely related to one another than either is to C. oligostachys.

Biology And Ecology

  • In Laos in silty bamboo scrub close to a seasonal stream at 150 m, in Thailand in evergreen forest at 200 m. (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. The species is so far known from only two localities but occurs in degraded habitats and is unlikely to be heavily harvested. Further research is required.

Common Name

  • wai kating (Lao Loum), wai kating (Thailand). (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 adequate for handicrafts but brittle. The shoot is edible but small. (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

Materials Examined

  • See Evans et al. (2000) (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
