oblong, attenuated below into a petiole ; cymules 2 - 3-flowered, somewhat paniculate ; the

Stems 5-8 inches high, slender, usually several from one root, 4-sided, the angles promi- 

 nent. Leaves about three-fourths of an inch long, and 1 - 2 lines wide ; the pairs somewhat 

 approximated. Stipules short and broad, but rather acute, scarious. Flowers about 3 lines 

 long. Corolla about three times as long as the lobes of the calyx, pale purple, or sometimes 

 nearly white. Capsule about half free from the calyx ; the cells about 10-seeded. 



Dry hill-sides, fields, etc. Catskill and Troy ; also abundant on Hempstead Plains, about 

 Oyster Bay, &c. Long Island. Fl. June - August. 



§ 2. Flowers all similar : corolla rotate, shorter than the calyx-teeth : capsule wholly adherent to the 

 calyx; the cells many- (GO or more) seeded : herb annual.

Stem erect or somewhat diffuse, hairy-pubescent, branching ; leaves oblong or elliptical- 

 lanceolate, narrowed at the base or slightly petioled, nearly smooth ; flowers mostly glomerate 

 in the axils; tube of the calyx hairy, shorter than the lobes. — Ell. sk. \.p. 187; Torr.fl. 1.

Whole plant of a dull green color. Stem 2-4 inches high, at first simple and erect, at 

 length branching from the base, and assurgent. Leaves about half an inch long ; upper ones 

 nearly sessile and crowded. Stipules adnate to the short petioles, cleft into two subulate 

 divisions. Flowers sometimes solitary, or 2 - 3 together, but usually clustered ; when few 

 or terminal, they are mostly pedicellate. Calyx with ovate foliaceous segments. Corolla 

 white ; tube very short : segments ovale, generally spinulous, one-third the length of the 

 calyx. Stamens scarcely exserted : anthers somewhat globose. Style almost none : stigmas 

 oblong, obtuse. Capsule large for the size of the flower, globose-didyraous, crowned with 

 the persistent teeth of the calyx. 



Moist and usually shady places. In a wet woods, Bloomingdale, on the Island of New-
