The characters on which Franchet (l. c.) based his varieties are inconstant and 
of no taxonomie value, being dependent upon situation, vigor and the season of 
the year.

This is à 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.
