Calamus endauensis J.Dransf., Malaysian Forester 41: 330 (1978)

Distribution

Johore; endemic. (Dransfield, J. 1979: A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.)A

This species is known from one collection from the foot of G. Janing, Ulu Endau in Johore on hillslopes in hill Dipterocarp forest at 200 m altitude.
This is a very distinctive species easily recognized by the characters emphasized above. It and C. ulur are the only species of rattan in Malaya that bear vestigial flagella. C. endau-ensis, unlike C. ulur, does not have partial whorls of spines, and the leaflets are much narrower. (Dransfield, J. 1979: A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.)A

Endau - from Ulu Endau, the type locality (Dransfield, J. 1979: A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.)A

Produces a cane of good appearance. (Dransfield, J. 1979: A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.)A
