Indo-China, Cho-Ganh, Dr. A. Petelot 942, June, 1923. On lime- 

 stone hills. 



A remarkably distinct species not at all closely allied to any of the 

 nine species known from Indo-China. It is well characterized by its 

 stellate, or in places, plumose indumentum, together with its vegetative 

 and inflorescence characters. Each primary branch of the inflorescence 

 bears about 20 umbels, each umbel being subtended by an oblong- 

 lanceolate, 5 mm. long bract.
