into the open throat, the acute petals with a spread of ?>-4 cm., color pure white 

 when open except for a blush of pink or purple on outside near base of ti'.])e; 

 the buds more pink. Calyx two-thirds to three-fourths as long as the fivary, 

 varying (in the North Carolina plant) to nearly as long, the strap-shaped lobes 

 blunt, unequal, and upright (recurved or revolute on drying at times), separate 

 to near or below the middle, glandular only or both glandular and with the 

 margin hairy; ovary about 4 mm. long and 3 mm. thick, style about 4-6 cm. 

 long, pale pink to greenish white, hairy (not glandular) over loAver half or two- 

 thirds, the knob-like stigma greenish brown; stamens well exserted (about 

 2 em.), but not nearly so much so as in A. nudiflora, Avhitish or pale green; pedi- 

 cels about 7-13 mm. long, pink or greenish. Mature pods about 2 cm. long and 

 6-7 mm. thick, pointed, somewhat curved, nearly glabrous, dark. Floral glands 

 reddish, very short-stalked, present on pedicels, calyx, ovary and on the outside 

 of the corolla tube and along the central keels of the spreading lobes. Odor 

 strong and very pleasant. 



Azalea atlantica var. luteo-alba n. var. 



Flowers smaller, white when open, the buds and opening flowers with a de- 

 cided yellowish tint ; not pinkish. Otherwise as in the type. Occurring in sim- 

 ilar habitats as the type but in separate colonies, and not intermixed. We have 

 found it only at Hartsville, S. C. 



A well-marked species that is easily distino-nished from A. nudi- 

 flora, which occurs plentifully in the same territory, though rarely 

 intermixed. It differs in the white, very fragrant, and viscid-glandu- 

 lar (not hairy) tlowers with longer tubes, more open throats, much 

 larger calyx, shorter and stouter ovary, and less exserted stamens; 

 by the dwarf size and extensive underground runners ; and by the 

 absence of cilia on the midrib. The habitat is also not the same, A. 

 atlantica being found in low, damp, undrained pine flats of the coastal 

 plain, while A. nudiflora prefers the better-drained soil by ditches, 

 branches or bluffs and extends far beyond the range of the former. 

 Azalea viscosa, which is really nearest, is, of course easily distinguished 

 by large size, late flowering (late May to July), and different habitat 

 and habit. It is the only other Azalea of the region occupied by 

 A. atlantica and A. nudiflora, with the possible exception of the next. 

 Azalea canescens, which has the leaves whitish-pubescent below, occurs 

 on better-drained soil, is rose-flowered, is not viscid, and has the same 

 size and habit as A. nudiflora, which is very near. Compared with 

 specimens of A. canescens at the New York Botanical Garden our 

 plants were easily seen to be different. One plant from Orangeburg, 

 S. C, in the New York Botanical Garden Herbarium, labelled A.
