An account of the Papuasian species of Calamus (Arecaceae) with paired fruit

From: Kew Bulletin | Date: January 1, 2003| Author: | Copyright information

Summary: A taxonomy is proposed for Papuasian species of Calamus (Arecaceae) in which the fruits are borne in pairs, rather than singly. Five species are recognised. Calamus pholidoslachys J. Dransf. & W. J. Baker is described as new, C. macrospadix Burret is reduced to synonymy with C. macrochlamys Becc., C. steenisii Furtado and C. laceratus Burret are both reduced to synonymy with C. zebnnus Becc., C. altiscandens Burret is accepted and the until now poorly known C. fertilis Becc. is fully described for the first time.

The subject of this paper is a group of five Papuasian species of ...
