Discussion

  • This species has been recorded once from a low hillside and once from forest on limestone.
    It seems closest to C. balingensis but may be distinguished by its much smaller size, the narrow bristly leaflets, and the spine-free petiole base. (J. Dransfield, A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.. 1979)A

Common Name
