Notes on the identity of Calamus delessertianus Becc.

Abstract

Calamus delessertianus Becc. was originally reported from South India based on a collection by Roxburgh. Later Beccari suggested that this species should be eleminated since he suspected this Roxburghian material as a specimen of C. tenuis. A detailed study of the rattans of India has proved that the Roxburghian species is not C. tenuis and C. delessertianus is a separate species. In this paper a complete description of this species is given and the field identification features are discussed.
