    Vernacular
    wai tia, wai kok, wai foom, wai nang (Lao Loum), wai pum (Thailand), padao kui (Khmer language, Thailand).
    Biology
    Open deciduous habitats below 200 m. Unusually for a rattan this species tolerates fires and thrives in frequently-burnt areas (Evans & Sengdala 2001).
    Conservation
    Unlikely to be under threat given the large number of records within its relatively small range, the lack of harvesting and the tolerance of both deciduous habitats and fire.
    Distribution
    Indochinese endemic. Thailand (North-east and East), Laos (Central and South).
    [PW]
    Use
    The root can be used to treat malaria (Vidal 1963), to increase the strength of the arrow poison from Strophanthus fruit (Kerr, A. 8233) or as a medicine after childbirth (Hurlburt 21). No other Indochinese rattan has more than one recorded pharmacological use. The leaves are occasionally used to make brooms.
