woody stems are perfectly simple, and not more than an 

 inch or two high ; and there is no trace of any offset by 

 which it can be increased. It is, however, setting its 

 fruit freely, so that it is likely to become a common plant. 



It is very hardy, but it cannot bear that the extremity 

 of its stem should be removed. It seems as if it had no, 

 or very little, power of developing new axillary buds when 

 the terminal one is destroyed; so that if injured, it either 

 dies outright, or remains in a stunted state. 



The leaves are remarkable for the deep purple they 

 acquire in the autumn. The flowering season is March 

 and April. 



Berberis nervosa of Pursh is a spurious species, made up 

 of the leaves of B. glumacea and the flowers of B. Aqui- 

 folium, and therefore must be expunged from the genus. 

 This error was, we believe, first detected by Mr. Douglas, 

 from an inspection of Pursh's specimens in Mr. Lambert's 

 Herbarium ; and it was on this account that all the plants 

 distributed by the Horticultural Society have been named 

 B. glumacea.
