Spec. Char., Sfc. Branches hairy. Leaves lanceolate, ciliated, 

 acute at both ends. Calyx pubescent. Corolla silky, with ■^- 

 obtuse, ciliated, lanceolate, undulated segments. Stamens ^ 

 exserted. (Don's Mill., iii. p. 848.) We are strongly IJ^^'W^ 



inclined to think that this, and several other sorts, which, | 



in conformity with the practice of modern writers, we \ 950 



have treated as species, are only varieties ; in short, it would not surprise 

 lis, if ultimately it should turn out that there was only one species of Azalea 

 indigenous to North America, and one species to Asia.

 (Don's Mill., iii. p. 847.) Pursh, writing of this species, in 1814, says, " This 

 beautiful species has, to my knowledge, not yet been introduced into the 

 gardens. I have only seen it in its native place, and in the garden of Mr. 

 John Bartram, near Philadelphia, whose father introduced it many years 

 ago. It rises from 10ft. to 15ft. high; and forms, with its elegant foliage, 

 and large, abundant, rose-coloured flowers, the finest ornamental shrub 

 I know. The flowers are not so pubescent as those of the other 

 species. The scales of the flower buds are large, yellowish brown, and 

 surrounded with a fringed white border." (Pursh Fl.Amer. Sept., i. p. 153.) 

 It was introduced in 1818 ; and there are plants of it at Messrs. Loddiges's; 

 but it is not frequent in collections.
