The Swamp Honeysuckle. 



Azalea viscosa, Willd., Sp. PL, vol. i. p. 831. Pursh, Flor. Amer. Sept., vol. i. p. 153. 

 — Pentandria Monogynia, Linn. — Rhododendra, Juss. 



The leaves of this species of Azalea are oblongo-obovate, acute, smooth on 

 both sides; the flowers white, sweet-scented, with a very short calyx. It 

 grows abundantly in almost every district of the United States, in such 

 localities as are suited to it, namely, low damp meadows, swamps, and shady 

 woods.

 notes, I observed, were uttered when on the point of leaving the branch. 

 The pair chased the insects as if acting in concert, and doubtless had a nest 

 in the immediate neighbourhood, although I was unable to discover it. It
