Berberis verruculosa, here figured, one of the most distinct 
and attractive of the newer Chinese species of the genus, 
was discovered in 1904 on the mountains around Tatien-lu, 
in Western Szechuan, by Mr. E. H. Wilson during his 
second expedition to China undertaken on behalf of Messrs. 
J. Veitch and Sons. It is most closely allied to B. pruinosa, 
Franch., a native of the province of Yunnan, but differs 
from that species in its verruculose branches and in having 
fewer and larger flowers. The material from which our 
plate has been prepared was obtained from a plant pre- 
sented to the Kew collection by the Messrs. Veitch in 1909. 
B. verruculosa forms a sturdy low bush of dense habit with 
stiffly arched branches and dark lustrous foliage. It is 
apparently very hardy, and its neat habit and slow growth 
make it especially well adapted for the Rock Garden. It 
has not yet borne seeds freely, but it can be propagated by 
SepremBer, 1912.
