Spec, Char., Sfc. Branches ascending. Spines rigid, straightish, now short, 

 now very long. Leaves some obovate, some oval, gashedly serrated, acute; 

 at the base wedge-shaped, glabrous ; in the autumn, remarkably leathery, 

 and they then acquire a purplish cast, and are shining, {Lindl.) A shrub 

 or low tree. North-West America. Height 10 ft. to 15 ft. Introduced in 

 1827. Flowers white ; May. Fruit small, dark purple ; ripe in August. 

 Decaying leaves purplish, leathery, shining, falling oif early, like those of 

 C. punctata and C. pynioYia. Naked young wood purplish. 



This is a very distinct sort, more particularly as it respects the colour of 

 the fruit, and the colour and texture of the leaves. The general habit of the 

 plant is fastigiate ; and it is one of the latest kinds in leafing in the spring. 

 The flowers and fruit are produced in great abundance, and both are very 

 ornamental.
