Calyx-tube not produced above the ovary: the 4-parted decid- 
uous limb reflexed. Petals 4, white or rose-colored, very small, 
obovate or oval with a very short claw. Stamens 8; anthers 
broad or rounded, attached by the middle, those opposite to the 
petals on shorter filaments and usually sterile. Ovary 2-celled: 
style short: stigma capitate or clavate. Capsule membranaceous, 
clavate, 2-celled, 4-valved. Seeds few to many, in one row in each 
cell, small, smooth, oblong, naked, ascending. Very slender 
branching annuals, of Western North America and Chili, with’ 
linear entire leaves and axillary flowers. The following are the 
only North American species known: 
G. lasiospermum Greene Pitt. ii, 164. Stems 10-12 inches high, 
loosely dichotomous with filiform branches: the upper leaves and inflor- 
escence more or less canescent with appressed or spreading short hairs: 
leaves ascending; flowers small, the petals about a line long: shorter 
stamens with small anthers: stigma globose, about 2 lines in diameter: 
capsule erect, about equalling the subtending leaves, narrowly linear or 
slightly clavate, scarcely torulose, on slender pedicels about 2 lines long: 
seeds mostly numerous, erect, not papillate, finely appressed pubescent 
In the high mountains, Washington to Southern California. 
G. diffusum T.&G_ FI. i, 513. Minutely pubescent above especially 
when young, stems very slender, 6-18 inches high diffusely much 
branched above; leaves linear-spatulate to linear, the lower obtuse, the 
upper acute or acuminate; flowers 2 lines in diameter, petals ovate a line 
or less long; stamens all fertile; stigma small clavate; pod linear-subu- 
late, minutely canescent, attenuate below to a slender pedicel; the cells 
4-8-seeded Brit Columbia to California and the Rocky Mountains. 
G. eriospermum Coville Bot Death Valley Exp. 103. Stems 12-20 
inches high, glabrous, widely branching: leaves narrowly linear, acute, 
attenuate at base, the largest 2 inches long and 3 lines broad: pedicels 4-8 
lines long, erect: ovary appressed-pubescent: calyx-lobes 2 lines long, 
sparingly appressed-hairy: petals 3-4 lines long, obovate, rose-colored in 
age: capsule erect, about 5 lines long, torulose, commonly &Ithseeded ., 
seeds a line long, narrowly obovate, densely pubescent. In the mountains 
of Scutheastern Uregon to u.iddle California. 
G. ramosissmum T. &G. Fl. i, 5138. Glabrous or the inflorescence 
sometimes puberulent, diffusely much branched 6-18 inches high; leaves 
an inch long or less: flowers half a line long, mostly near the ends of the 
branches; capsule oblong, two or three lines long, on pedicels about the 
same length or shorter, often deflexed; 3-5-seeded. Eastern Oregon to 
Mariposa county, California. 
. G. racemosum T. & G.1.c. Glabrous or more or les3 canescent with 
short appressed hairs; 6-18 inches high, the elongated branches mostly 
. simple; flowers half a line long, axillary the whole length of the branches; 
| capsules linear, sessile or very shortly pedicelled, 8-1) lines long, usually 
| many-seeded. Brit. Columbia to California. .
