570 WILSON EXPEDITION TO CHINA 



Yunnan: Szemao, mountains west, alt. 1600 m., A. Henry (No. 11909); 

 Puerh Fu, alt. 1800 m., A. Henry (No. 13297). 



This species does not seem to have been reported before from China. The 

 leaves of Henry's No. 11909 show a slight tendency toward lobing, otherwise the 

 specimens agree perfectly with those from Sikkim.

Of Delavay's No. 3718 I have only a few detached leaves with fruits before me
