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. (Dransfield, J. 1979: A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.)A
