the veins and midrib undernealh. Flowers in terminal clusters, about as large as in the 

 common Woodbine, usually appearing before the leaves expand, and hence appearing naked : 

 pedicels about one-third of an inch long. Calyx very short and hairy. Corolla rose-color, 

 more or less intense ; the lobes ovate-oblong, acuminate : tube hairy. Stamens nearly twice 

 as long as the corolla : filaments pubescent below the middle. Style a little longer than the 

 stamens. 



Woods and bushy places ; common. Fl. April - Ma}'. Fr. August. A very beautiful 

 shrub, of which there are numerous varieties in cultivation. 



4. Rhododendron viscosum, Torr. (PI. LXVI.) White Wild Honeysuckle. 



Branchlets hispid ; leaves obovate-oblong, the midrib and petiole bristly ; flowers appearing 

 with the leaves, very viscid , the tube nearly twice as long as the segments ; stamens slightly 

 exserted. — Torr. fl. I. p. 424 ; Beck, hot. p. 221 ; Darlingt. fl. Cest. p. 261 ; Hook. fl. 

 Bor.-Am. 2. p. 42. Azalea viscosa, Linn. sp. 1. p. 151 ; Michx.fl. 1. p. 150 ; Pursh,fl. I. 

 p. 153 ; Ell. sk. 1. p. 241 ; Bigel. fl. Bost. p. 82 ; DC. prodr. 7. p. 715. 



A shrub 4-7 feet high, with numerous spreading branches and a grayish bark. Leaves 

 1—2 inches long, acute or rather obtuse, cuneate at the base, often glaucous underneath ; 

 the margin bristly-ciliolate. Flowers in dense terminal clusters, very fragrant, pubescent and 

 glutinous. Corolla usually white, but sometimes tinged with rose-color ; the tube long and 

 slender. Anthers nearly twice as large as in the preceding species. 



Bushy moist places, and in woods ; not common in the interior of the State, but abundant 

 near New-York and on Long Island. Fl. June — July, or sometimes as late as August. 

 Azalea glauca of authors is scarcely even a variety of this species. 



5. Rhododendron hispidum, Torr. Hispid Azalea. 



Flowers appearing with the leaves ; branches strict and very hispid ; leaves narrowly 

 lanceolate, hispid above, smooth underneath, glaucous on both sides, the midrib bristly, ciliate 

 on the margin ; flowers very viscid ; tube of the corolla scarcely longer than the broad seg- 

 ments ; teeth of the calyx oblong, rounded ; filaments exserted {Pursh). — Torr.fl. I. p. 425 ; 

 Beck, hot. p. 221. Azalea hispida, Pursh, fl. 1 p. 154; Wats, dendr. Brit. t. 6 ; DC. 

 prodr. 7. p. 716. 



An upright shrub, 10-15 feet high, of a bluish appearance. Flowers white with a red 

 border and a tinge of red on the tube, which makes them appear of a rose-color before they 

 open. They have frequently ten stamens {Pursh). . . 



Borders of high mountain lakes, New-York to Pennsylvania. July - August {Pursh). 

 I have not found this species within the limits of the State. It is scarcely distinct from R. 

 viscosum.
