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 off early, like those of 
C. punctata and C. pyrifolia, 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.
