Spec Char., #c. Branchlets hispid. Leaves oblanceolate, acute, glabrous on 

 both surfaces, glaucous beneath, ciliated on the margins, having the midrib 

 bristly. Flowers very clammy, leafy. Tube of corolla twice longer than 

 the segments. Calyx very short. Filaments about equal in length to the 

 segments of the corolla. (Dun's Mill., iii. p. 848.) The shrub is dwarfer 

 than any of the other North American species of Azalea; and it produces 

 its fragrant white flowers in great abundance. Nuttall considers this as 

 only a variety of R. viscosuin, differing in nothing but in the under surface of 

 the leaves being glaucous; in which opinion we concur. It is a native of 

 North America, from New England to Virginia, in swamps of a clayey 

 soil ; where it forms a shrub, growing about 2 ft. high, and flowering in June 

 and July. Introduced in 1734, and common in gardens.

Spec. Char., fyc. Branches straight, very hispid. Leaves long-lanceolate, hispid 

 above, and smooth beneath, glaucous on both surfaces, ciliated on the 

 margins, having the nerves bristly beneath. Flowers 

 very clammy, leafy. Tube of corolla wide, scarcely 

 longer than the segments. Teeth of calyx oblong, 

 rounded. Filaments exserted. (Don's Mill., iii. p. 487.) 

 The flowers are white, with a red border, and a tinge 

 of red on the tube, which makes them appear to be of 

 a rose colour before expansion ; and they have some- 

 times 10 stamens. This sort may be distinguished 

 from the other hardy azaleas by its bluish appearance. 

 It is found wild in New York and Pennsylvania, on 

 the borders of lakes on the highest part of the Blue 

 Mountains; where it grows from 10ft. to 15ft. high, 

 and flowers in July and August. It was introduced in 1734, and is now 

 to be met with in most collections.

 late, rather mucronate, coriaceous, smooth on both 

 surfaces, shining above, having the nerve bristly beneath, 

 with revolute ciliated margins. Flowers clammy, leafy. 

 Tube of corollas little longer than the segments. Calyx 

 very .short. Filaments exserted. ( Den's Mill., iii. p. 847.) 

 The flowers are white, tinged with red; and the leaves 

 dark green and shining. They are also smaller than 

 those of any other hard) specie* of Azalea. The plan
