Discussion

  • Nothing is known of the ecology of this imperfectly known species. It seems very distinctive in its leaf sheath armature, the ecirrate leaves and the leaflets densely spinulose below. It might be confused with C. setulosus but the latter is very much smaller in size and has different armature on the sheaths. (J. Dransfield, A Manual of the rattans of the Malay Peninsula.
