The characters on which Franchet (1. c.) based his varieties are inconstant and 

 of no taxonomic value, being dependent upon situation, vigor and the season of 

 the year.

This is a common tree in moist woods and by the side of streams in western 

 Hupeh between 1200-2000 m. altitude. The bark is fibrous, smooth and pale gray, 

 becoming deeply fissured on the trunk of old trees. The number of leaflets varies 

 from 7 to 13. 



In Hupeh a colloquial name for this tree is Shan-liu-shu. 



The specimen from Szech'uan (No. 4141) is fragmentary and may possibly 

 belong to P. Delavayi Franchet, which we have not seen.
