1500-2700 m., July 1908 (No. 3041). Western Hupeh: Fang 
Hsien, alt. 2100 m., November 1907 (No. 581). 
Allied to P. subcanus from which it chiefly differs in the unusually large leaves of 
the flowering branchlets. No. 581, though differing from the type in the subglabrous 
leaves and the glabrous apex of the fruit, probably belongs to this species.

: Besides in other characters it differs from P. subcanus in the longer and more 
rigid hairs which cover the ovary and the sepals.
