Spec Char. $c. Leaves cuneate-obovate, acute, finely 

 serrated at top, clothed with white tomentum be- 

 neath. Racemes spicate, simple, bracteate, villously 

 tomentose. This is a very distinct species, although 

 it has been considered by some as a mere variety of 

 ooo /"\ the P re ceding. (Don's Mill., iii. p. 



842.) It is a native of North Ame- 



rica, in Virginia and Carolina, in 



swamps; where it forms a shrub 



growing from 3 ft. to 4 ft. high, and

 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.
