 North America, from New England to Virginia, 

 in swamps; where it forms a shrub growing 

 from .3 ft. to 4 ft. high, and producing its white 

 flowers from July to September. It was intro- 

 duced in 17.31 ; and is frequent in British gar-

 it has been considered by some as a mere variety of 

 the preceding. (1)oh\s Mill., iii. p, 

 842.) It is a native of North Ame- 

 rica, in Virginia and Carolina, in

 It is a native of Carolina, where it is a shrub growing 3 ft. or 4 ft. high, 

 and flowering from July to October. Said to have been introduced in 

 1770 ; but the plants which bear this name in British gardens appear to 

 be nothing more than C. alnifolia.
