Singapore : Bukit Mandai (Ridley 6280) ; Garden Jungle (Ridley 

 9850, 10861) ; Perak : Thaiping (Kunstler 5527, 8434) ; Selangor : 

 Kwala Lumpur (Ridley 3495), Kemaman (Vaughan Stevens), Batang 

 Berjuntai (Ridley 7881). Native name " Rotan Chichi." The stem 

 is indistinguishable from that of C. Eidleyanus.

Singapore : Garden Jungle (Ridley 11468); Mandai (3504) ; Johor : 

 Gunong Pulai (12202). Endemic. The stem and foliage exactly resem- 

 ble those of C. dcnsiflorus, but the elongate inflorescence and spiny 

 spathes and spathels and stout spikes make it quite distinct.
