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

 coarsely serrated above, glabrous on both sur- 

 faces, and of the same colour. Racemes spicate, 

 simple, bracteate, clothed with hairy tomentum. 

 (Don's Mill., hi. p. 841.) It is a native of 

 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 1731; and is frequent in British gar- 

 dens, among other peat-earth shrubs, where it is valued for its flowers.

Spec Char. Src. 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 

 the preceding. (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 

 flowering from July to October. It 

 was introduced in 1731, and is fre- 

 quent in collections.

Spec. Char., fyc. Leaves narrow, cuneate-lanceolate, acute, acuminately ser- 

 rated, glabrous on both surfaces. Panicle terminal, elongated, composed 

 of racemes, and clothed with white tomentum. (Don's Mill., iii. p. 842.) 

 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.

Spec. Char., Src. Leaves oval, acuminated, bluntish at the base, serrated, 

 glabrous on both surfaces, rather glaucous beneath. Racemes spicate, almost 

 solitary, bracteate, clothed with white tomentum. Flowers resembling 

 those of C. alnifolia. (Don's Mill., iii. p. 842.) It is a native of Carolina, 

 on the high mountains ; where it forms a large shrub, or low tree, growing 

 from 10 ft. to 15 ft. high, and flowering from July to October. It was 

 introduced in 1800, and is frequent in collections.
