Hupeh, A. Henry (No. 5308). 



I do not know of which species this plant could possibly be a variety. Therefore 

 I have considered it as a distinct species. 



At the request of Mr. Wilson this species has been named in compliment to 

 Monsieur Wilden of the French Consular service in China, stationed at Chengtu 

 in 1908, who rendered Wilson valuable assistance.
