1923] REHDER, THE LIGNEOUS PLANTS OF NORTHERN CHINA 185 



Distribution: also Hupeh, Szechuan. 



To this species I have referred the plant collected by Loczy in Kansu 

 and determined by Kanitz as C. Benthamiana Hemsl., as it appears very 

 unlikely that the latter, which seems to be confined to eastern China, 

 occurs in Kansu, while the closely related and similar C. obscura Maxim, 

 is a Kansu plant based on material collected by Potanin.
