Discussion

  • This species was collected in montane forest at 1,300 altitude.
    This very slender rattan appears to be the only properly climbing (as opposed to sprawling) rattan in the C. perakensis complex. It is easily distinguished by the presence of a knee of the leaf sheath, albeit poorly developed, and the few very divaricate leaflets scarcely longer than 25 cm. (J. Dransfield, A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.. 1979)A
