 Alor Sta (14884), Perlis, Chupeng (14885), Setul (14886), 

 also Penang Hill (Ridley, 10209). 



This plant is extremely abundant over Lankawi and 

 the mainland opposite. It is allied to C. hirsutulus and 

 to C. meinbranaceus, Hook. til. but its small leaves, larger 

 flowers, and different petals, acuminate sepals make it 

 very distinct.
