Negri Sembilan: known only from Bt. Senaling near Kuala Pilah. (J. Dransfield, A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.. 1979)A

Discussion

  • I had confused this species with Calamus moorhousei, itself only known from one collection from Kuala Pilah, but this latter species, although imperfectly known is quite distinct from C. senalingensis. Superficially C. senalingensis is like C. laevigatus in its reflexed leaflets but of course C. laevigatus does not bear flagella and the leaves are cirrate. (J. Dransfield, A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.. 1979)A

Etymology

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

Uses

  • Not known. (J. Dransfield, A Manual of the rattans of the Malay Peninsula. Malayan Forest Recirds 29.. 1979)A
