Discussion

  • 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. (J. Dransfield, A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.. 1979)A

Etymology

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

Uses

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