Calamus species – Plant

Description

Calamus is a genus of the palm family Arecaceae. These are among several genera known as rattan palms. There are an estimated 400 species in this genus, all native to tropical and subtropical Asia, Africa, and Australia.They are mostly leaf-climbing lianas with slender, reedy stems. To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified “pinnae” or tendrils in the form of stout, backward-pointing spines. These stems may grow to lengths of 200 metres.
