Spec. Char., Sfc. Branchlets hispid. Leaves oblanceolate, 

 acute, glabrous on both surfaces, glaucous beneath, cili- 

 ated 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. (Don's Mill.) 

 A deciduous shrub. New England to Virginia, in 

 swamps in clayey soil. Height 2 ft. Introduced in 1734. 

 Flowers white ; June and July. 



This 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 it as only a variety of 

 R. viscosum, differing in nothing but in the under surface of the leaves being 

 glaucous; in which opinion we concur.
