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 : 



* 0. lasiospermum Greene Pitt, ii, 164. Stems 10-12 inches high, 

 loosely dichotomous with Aliform 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 diauieter : 

 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. 

 Jn the high mountains, Washington to Southern California. 



(t. diit'usum T. & G Fl. 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. eriospermnm 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 8-1 0-seeded : 

 seeds a line long, narrowly obovate, densely pubescent. In the mountains 

 of Southeastern Oregon to twiddle California. 



G. ramosissmnm T. & G. Fl. i, 513. 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 less 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-lu lines long, usually
