Spec. Char., fyc. Leaves with two glands at the base 

 of the disk, which is oblong-lanceolate, acuminate, 

 and glabrous. Flowers disposed in grouped sessile 

 umbels, which have something of the character of 

 panicles. (Dec. Prod.) A shrub. North America, from 

 New England to Virginia, in woods and plantations. 

 Height 6 ft. to 8 ft. Introduced in 1 773. Flowers 

 white ; May. Drupe black, small, but agreeable to 

 eat ; ripe in July. 



Sir W. J- Hooker considers this sort as synonymous 

 with C. borealts Michx., in which he may probably be 

 correct We have, however, kept them distinct ; not 

 only because the whole genus appears in a state of con- 

 fusion, but because, though C. pennsylvanica is said to 

 have been introduced in 1773, we have never seen the plant in a healthy state, 

 and, consequently, feel unable to give any decided opinion respecting it.

Mant. 74., Bot. Mag. t. 2176., and of the 



Hammersmith and other nurseries. (Our 



figs. 467, and 468.) Flowers semidouble, 



pink like those of the species. 



There are two shrubs in British nurseries 



often confounded under the name of A. 



pumila. The one is that now described, 



which may be known at any season by the 



purplish or brownish red colour of the 



bark of its young shoots ; and, in summer, 

 by its glabrous finely serrated leaves, which have a
