Distribution

Map uses TDWG level 3 distributions (http://www.nhm.ac.uk/hosted_sites/tdwg/geogrphy.html)
Laos present (World Checklist of Arecaceae)B
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

  • Beccari (1908) placed the locality in Cochinchina but this, and his spelling of it, were in error. The rediscovery of this species was described by Evans (2000). Unconfirmed reports of the species from North Thailand (Evans 2000) are now known to refer to Calamus erectus. (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

  • Evergreen forest at 150 - 200 m. (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

  • The species is currently of conservation concern because it is known from only one site. The locality adjoins a very extensive area of forests at similar altitudes, exploration of which may reveal that it is more abundant. The only threat known at present is forest clearance. (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

Common Name

  • nya seui (Lao Loum), yeu mo (Alak). (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

Uses

  • Fruits edible. (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
