G-. sphserocarpa, BU. 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

 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. 



-i— Corolla golden yellow. 

 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.

 lanceolate, distinctly 3-nerved, entire or sparingly serrulate (an inch or more long), all ex- 

 ceeding the pedicels and fiower : bractlets usually exceeding the calyx : corolla 8 or 10 

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

 Dan. t. .363; Benth. 1. c. ; Chapm. 1. c. (but corolla not "pale yellow"), not Michx. — 

 Georgia, Le Conte, in herb. Torr. As this specimen is the only known authority, it is ques- 

 tionable whether it is really of American origin. (Eu., N. Asia.) 

 i G. viscosa, Sohwein. Viscid-puberulent or pubescent, a span high, rather simple : 

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

 (one or two-thirds inch long), shorter than the pedicels: sepals and bractlets broadly or 

 ovate-lanceolate : corolla 5 lines long : sterile filaments short : capsule shorter than calyx. 



— LeConte in Ann. Lye. N. Y. i. 106; Benth. 1. c. — N. Carolina and Kentucky to Georgia, 

 in the upper country. 



- G. Drummondi, Benth. 1. c. Puberulent and somewhat viscid, a span or two high : 

 leaves lanceolate, acute, sparsely and acutely serrate (6 to 10 lines long), about equalling 

 the pedicels : sepals and bractlets linear-subulate, much longer than the capsule : corolla 

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

 Louisiana, and Texas. 



++ ■*■* Bractlets minute or obsolete. 



. G. ramosa, Walt. Minutely viscid-puberulent, a span or more high : leaves lanceolate 

 or linear-lanceolate, acute, serrate with sharp coarse teeth (6 to 10 lines long), equalling 

 or shorter tlian the pedicels : sepals linear (2 or 3 lines long), half the length of the corolla : 

 sterile filaments filiform. — Car. 61. G. Virginica, Lam. 111. t. 16, fig. 2. G. quadridentata, 

 Michx. Fl. i. 6; Ell. 1. c. ; Benth. 1. c. (tliis specific name later and no better than that of
