Discussion

  • Calmus peregrinus is a rather local rattan of generally northern distribution in Malaya. It has been found on steep hillslopes and ridges in hill Dipterocarp forest, at altitudes up to 600 m. Because of its very large size and ecirrate leaves it could be confused with Calamus ornatus, but can be easily distinguished from the latter by the much narrower leaflets and the bright yellow green colour of the fresh plant. The long inflorescence with its 2-3 partial inflorescences very close to the insertion and the long terminal flagellum is very characteristic. (J. Dransfield, A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.. 1979)A
