The very distinct Berberis here figured is a native of 
Western China. It was originally described by Dr. C. K. 
Schneider as . aggregata from a flowering specimen 
collected by Potanin in Eastern Kansu with which he 
associated a fruiting specimen gathered by E. H. Wilson 
in Szechuan. It was at first placed by its author in the 
section Sinenses next to B. Wilsonae, Hemsl. Subse- 
quently, however, the opportunity of studying further 
material obtained by Wilson in Szechuan, induced its 
author to transfer B. aggregata, on account of its 
inflorescence, to the section Polyanthae. The material 
for our plate has been obtained from a plant raised at 
Kew in 1911, from seed purchased from the Arnold 
Arboretum which had been collected by Mr. Wilson in 
October, 1910, in the Min Valley, Western Szechuan. As
