Discussion

  • This variety which seems to be distinct, is only known from a few collections from Perak. The specimen collected by Ridley from Johore quoted by Furtado, is in my opinion a well-grown plant of C. insignis var. insignis. (J. Dransfield, A Manual of the rattans of the Malay Peninsula.
