Indochinese endemic, known only from the type locality. (T. Evans & K. Sengdala & B. Thammavong & O.V. Viengkham & J. Dransfield, A Synopsis of the Rattans (Arecaceae: Calamoideae) of Laos and Neighbouring Parts of Indochina. 2002)A

Discussion

  • Gagnepain & Conrard (1937) cited a second locality, "Long Tcheou" in Tonkin, which is now believed to lie in Guangxi, China. It was not possible to re- examine this specimen during the study but its identification should be carefully re- assessed since several other erect species have been described from South-east China since 1937 (Wei 1986). Vu Van Dung & Le Huy Guang (1996) report the species at two new localities in South Annam but cite no specimens to support this. (T. Evans & K. Sengdala & B. Thammavong & O.V. Viengkham & J. Dransfield, A Synopsis of the Rattans (Arecaceae: Calamoideae) of Laos and Neighbouring Parts of Indochina. 2002)A

Biology And Ecology

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

Conservation

  • Unknown, but likely to be poor. Habitat loss has probably been severe in this heavily populated part of Vietnam. (T. Evans & K. Sengdala & B. Thammavong & O.V. Viengkham & J. Dransfield, A Synopsis of the Rattans (Arecaceae: Calamoideae) of Laos and Neighbouring Parts of Indochina. 2002)A
