460 POLEMONIACE^ gilia 



POLEMONIUM 



effuse cymose panicle; flowers inconspicuous; corolla white, 2-3 lines long, 

 fully twice the length of the calyx, slender-funnelform, with very small 

 acute lobes: capsule ovoid, equalling or exceeding the triangular acute 

 calyx-teeth. Eastern Washington and Oregon to Nevada and Utah. 



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

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

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

 curving inward in age; leaves all alternate, spatulate-lanceolate, 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 crowded 

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

 ualling the corolla, becoming Fcarious 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 unequally 

 inserted, entirely included in the lower half of the tube : ovary 2-celled; style 

 short, one-half the length of the corolla: mature capsule oblong, 1-2 lines 

 long with about eight ventricose swellings on each valve marking the posi- 

 tion of the seeds; seeds 10-12, black, wrinkled, the coats not developing 

 mucilage when wetted. In drifting sand at Pasco Washington. 



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

 or reflexed : corolla campanulate or rotate. 



G. micromeria Gray 1. c. Nearly glabrous, glandless, effusely 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 campanulate, 

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

 Northwest Nevada, to be looked for in adjacent Oregon. 



G. flliformis 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-den- 

 tate: 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 Fhort-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 Washington 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. capillar is Kellogg Proc. Cal. Acad. v. 49. Slender annual 2-18 

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