This Western Szechuan shrub was first collected by Mr. 
A. E. Pratt in the neighbourhood of Tachien-lu. It was 
subsequently met with there and at Mupine by Mr. E. H. 
Wilson, when collecting for Messrs. J. Veitch and Sons, 
Originally included by Hemsley in B. polyantha, this Ber- 
beris has been kept apart by Schneider on account of its 
less closely reticulated leaves and narrower inflorescences, 
But while perhaps most closely related to B. polyantha, 
Hemsl., B. Prattii most resembles B. brevipaniculata, C. K. 
Schneid., with which it has been confused in collections, 
though it is readily distinguished by the pale green but 
not glaucous lower surface of the leaves. Like B. brevi- 
paniculata our plant is a shrub of dense growth, forming 
ApriL, 1914.
