Engravings. Bot. Reg., t. 1810. ; our fig. 697. in p. 393.; the plate of the species in Arb. Brit., 

 1st edit., vol. vi. ; and our fig. 648. 



Spec. Char., fyc. 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 10ft. to 15ft. Introduced in 

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

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

 C. punctata and C. joyrifolia. 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.
