This is a very common subscandent shrub at low altitudes through western 



China, especially in rocky places. The numerous specimens before us exhibit 



considerable variation in size of the leaflets but all agree in having a terminal 



inflorescence, shortly beaked fruit, and shoots slightly pruinose the first year. 



The specimen from Mount Omei is the most extreme and may possibly constitute 



a well-marked variety. Henry's No. 9874 from Yunnan possibly belongs here but 



the inflorescence is very compact an'd The pedicels are stout and more or less 4- 

 sided. 



Zanthoxylum stenophyllum Hemsley, is closely related to Z. oxypkyllum Edge- 

 worth, which has larger leaves and flowers and axillary and terminal corymbs.
