G. sphserocarpa, Ell. Glabrous or nearly so : stem thick, erect or ascending from a 

 procumbent creeping base, a span to a foot high : leaves from oblong-lanceolate to obovate- 

 oval, from acutely dentate to repand, narrow at base (an inch or two long) : corolla 5 or 6 

 lines long, white: capsule globose, large (2 lines in diameter), pointless, usually somewhat 

 surpassed by the calyx and bractlets. — Ell. Sk. i. 14; Benth. 1. c. ; Chapm. Fl. 292. G.

 Illinois to Florida and Texas. Remarkable for the size and rotundity of the capsule, and 

 the short pedicel. (Mex.) 



* * Sterile stamens conspicuously represented by a pair of filiform filaments with a minutely 

 capitate tip: cauline leaves seldom at all narrowed at the partly' clasping base: pedicels slender: 

 stems all more or less creeping at base, and somewhat quadrangular above.

G. aurea, Muhl. Glabrous or obscurely viscid-puberulent : leaves lanceolate, mostly 

 entire (5 to 10 lines long) : upper pedicels equalling the leaves : bractlets equalling the calyx, 

 longer than the globose-ovate capsule : corolla half an inch long : sterile filaments short.

 lines long: sterile filaments elongated: capsule ovate, acute. — Schkuhr, Handb. t. 2; Fl. 

 Dan. t. .363; Benth. I.e.; Chapm. I.e. (but corolla not "pale yellow"), not Michx. —

 leaves oblong or ovate-lanceolate, acutely dentate or denticulate, conspicuously clasping

 from 5 to 6 lines long : sterile filaments short. — Chapm. Fl. 293. — Georgia to Arkansas,
