Pahang. Tahan River Woods; Penang, Penara Bukit 
(Curtis, 3035). 
This is the plant recorded in DC. Monog. Phan., v. p. 196, 
as R. parviflorum? var. penangensis, but from a comparison 
with plants from Java and Sumatra, collected by Forbes, it 
appears to be identical with R. parviflorum, Blume. The genus 
Isanthera seems hardly distinguishable from Rhynchotechum, and 
would probably be better merged in it.
