Western Szech'uan: Wa-ssu country, W6n-chuan Hsien, alt. 

 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 hi 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
