    [PW]
    Biology
    Evergreen forest. In Laos at 300 - 1300 m, in Thailand at 600 - 700 and in South Annam at 500 m.
    Conservation
    Of high conservation concern. Listed as Threatened- Rare in Vietnam (Phan Thuc Vat 1996). Although relatively widespread within Indochina, high harvesting pressure has already caused the collapse of many populations (e.g. in Laos, pers. obs.) and declines are undoubtedly continuing. Stem harvesting is the main threat, but shoot harvesting may threaten some remnant populations. The solitary habit hinders regeneration and harvests have been so thorough in many areas that very few mature fruiting stems remain.
    Vernacular
    wai thoon (Lao Loum), blong thoon (Khamu), gaparl (Phong), wai kruh (Thailand), probably also wai khom (Lao Loum), blong chang (Khamu), wai nampung (Thailand).
    Distribution
    Indochinese endemic, Thailand (North and North-east), Laos (Central and North) and Vietnam (South Annam and probably North Annam).

    Use
    Calamus poilanei is the most economically important rattan in Laos, dominating the export trade in raw cane and being the preferred species used by Lao artisans for the frames of furniture. The shoot is also edible. There are plantations of unknown extent in Vietnam (Nguyen Truong Thanh & Ngo Thi Min Duyen 1997).
