Indo-China, Cho-Ganb, Br. A. Petelot 1172 (type), 1173, October. 

 1923. On limestone hills. 



A distinct species belonging in the section PediceJlati, strongly 

 characterized by its relatively large, long pedicelled female flowers, 

 and its persistent accrescent sepals. An allied form is apparently 

 represented by Petelot 867 from the same locality. The specimen is in 

 fruit, has larger, fewer nerved, longer petioled leaves and densely 

 pubescent branchlets. Cleistanthus longipedicellatus is entirely 

 glabrous except for a few scattered hairs on the youngest branchlets.
