 teeth. Eastern Washington and Oregon to Nevada and Utah. 



G. hispida Piper Erythea vi, 30. "' Annual, prostrate, 3-5 inches in 

 diameter, hispid throughout with white hairs; stems usually purplish, 

 branched from the base in a falsely dichotomous manner, the branches 

 curving inward in age; leaves all alternate, spatulate-Ianceolate, acutish- 

 or the earliest truly spatulate and obtuse, 6-12 lines long, all tapering to 

 a narrowed base ; midrib prominent in age, the veins not visible : flowers 

 solitary and sessile in the forks or terminal, the latest ones loosely crowd- 

 ed in very leafy capitate clusters : calyx green, very hispid, the lobes nearly 

 equalling the corolla, becoming scarious at base in age; corolla pinkish, 

 tubular, 4 lines long, the lobes very short and obtuse, very slightly dilated 

 in the throat, sparsely hispid above both within and without; stamens un- 

 equally inserted, entirely included in the lower half of the tube : ovary 2- 

 celled ; style short, one-half the length of the corolla : mature capsule ob- 

 long, 1-2 lines long with about eight ventricose swellings on each valve 

 marking the position of the seeds ; seeds 10-12, black, wrinkled, the coats 

 not developing mucilage when wetted. In drifting sand at Pasco, Wash- 

 ington. 



** ** Pedicels slender or filiform, scattered, becoming horizontal or 



reflexed : corolla campanulate or rotate. 



G. micromeria Gray 1. c. Nearly glabrous, glandless, eflfusely much 

 branched ; branches filiform : radical and lower leaves pinnatifid, with ob- 

 tuse lobes ; the upper linear and entire : pedicels capillary, 6-7 lines long, 

 axillary, or opposite leaves : flowers barely a line long : corolla campanu- 

 late, white, a little longer than the 5-cleft calyx : capsule globular, few- 

 seeded. Northwest Nevada, to be looked for in adjacent Oregon. 



G. filiformis Parry, Gray Proc. Am. Acad, x, 75. Completely glab- 

 rous and smooth : stem erect with filiform spreading branches : leaves all 

 filiform or nearly so, entire : pedicels scattered, capillary, at length refract- 

 ed : corolla cream-color, very open-campanulate, 2 lines long, deeply 5- 

 cleft, exceeding the 5-parted calyx ; its lobes truncate and obscurely erose- 

 dentate : capsule globular : seeds few, developing mucilage but not spiral 

 threads when wetted. Eastern Washington to Utah. 



"■" ''" Much branched annuals with filiform or slender-subulate and 



entire or sometimes 3-parted leaves and short-campanulate 5-toothed 



calyx : flowers scattered, small : stamens inserted on and included in 



the tube of the corolla : ovules solitary in the cells. 



G. minutiflora Benth. DC. Prodr. ix, 315. Glabrous or minutely 

 glandular-puberulent above : stem erect, 10-20 inches high, with many 

 virgate and rigid, slender branches : upper leaves all reduced to minute 

 subulate appressed bracts, the lower larger and some of them 3-parted: 

 flowers 2 lines long, terminal and spicately disposed along the branchlets : 

 tube of the corolla about twice the length of the calyx and of its own 

 lobes : filaments slender : capsule ovoid : seeds oblong. Eastern Wash- 

 ington and Oregon to Idaho and Wyoming. 



G. tenerrima Gray Proc. Am. Acad, viii, 277. Minutely and sparsely 

 glandular: stem 4-10 inches high, effusely much branched with filiform 

 branches : leaves entire, linear-lanceolate : flowers loosely panicled, on 

 slender divergent pedicels, minute : calyx campanulate, the lanceolate 

 lobes equalling the tube : lobes of the corolla oblong, as long as the calyx : 

 capsule globular : seeds turgid-oval. Southeastern Oregon to Utah. 



G. capillaris Kellogg Proc. Cal. Acad. v. 49. Slender annual 2-18 

 inches high, glandular, otherwise glabrous, branching into an effuse pan- 

 icle : leaves 6-20 lines long or the uppermost reduced to small subulate
