1. Gilia micrantha (Kell.) A. Nels. Annual, puberulent or pubescent with 

 gland-tipped hairs, at length freely branched from the base, 5-15 cm. high, 

 as broad as high: leaves alternate, usually at the base of the branches, lanceo- 

 late or linear, 1-3 cm. long: flowers mostly geminate on short subequal pedi- 

 cels: calyx-teeth acute, about half the length of the tube: corolla white or 

 pale pink or violet, the tube usually subsurpassing the calyx: capsule elongated- 

 oval. G. gracilis. (Collomia micrantha Kell. Proc. Cal. Acad. 3: 18, 1863; 

 Microsteris micrantha Greene, Pitt. 3: 303. 1898; under various other names.) 

 TlTroughout our range and westward. 



2. Gilia Tweedyi Rydb. Bull. Torr. Hot. Club 31: 634. 1904. Annual, 

 branched, 1-4 dm. high; stem and branches glandular-puberulent, especially 

 above: leaves 1-3 cm. long, pinnatifid with lanceolate-cuspidate lobes, or the 

 uppermost entire: flowers paniculate; pedicels 1-8 mm. long: calyx about 

 3 mm. long, scarious between the green ribs, the lobes lanceolate: corolla 

 funnelform, barely exceeding the calyx, bluish: capsule ovoid, about 4 mm. 

 long. G. minutiflora. Colorado to Montana and Idaho. 



3. Gilia tenerrima Gray, Proc. Am. Acad. 8: 277. 1870. Slender annual, 

 1-3 dm. high, diffusely branched from the base with numerous, scattered, 

 divaricate, almost filiform branchlets, minutely glandular-pubescent: leaves 

 alternate, linear or the radical lanceolate, the upper much reduced, entire: 

 flowers small, solitary, terminal on the branchlets: corolla salverform, twice 

 as long as the calyx, white: capsule compressed-globose: seed-coats muci- 

 laginous. Western Wyoming, Utah, and Idaho. 



4. Gilia leptomeria Gray, 1. c. More or less glandular-pubescent; stem erect, 

 divaricately branched from base to summit, 6-15 cm. high: radical leaves 

 rosulate, oblong-linear, dentate to pinnatifid, teeth usually short-mucronate; 

 cauline leaves reduced and bract-like : flowers numerous, corymbose-paniculate: 

 calyx-teeth shorter than the tube: corolla white or rose-color, salverform, 4-6 

 mm. long, the tube nearly twice the length of the lobes and of the calyx: sta- 

 mens inserted in the throat: style as long as the corolla: ovules and seeds 2-3 

 in each cell of the globose capsule. Colorado to California. 



5. Gilia inconspicua (Smith) Dougl. Hook. Mag. 56: pi. 2883. 1829. One to 

 three or more dm. high, usually with slight woolly pubescence when young, and 

 viscid-glandular, often branching from the base: leaves mostly pinnatifid or 

 pinnately-parted, or the lowest bipinnatifid, with short, mucronate-cuspidate 

 lobes; the uppermost becoming small, subulate and entire: flowers either some- 

 what crowded and subsessile or at length loosely panicled and some of them 

 slender-pediceled : corolla violet or purplish, 5-10 mm. long, narrowly funnel- 

 form, the lobes oval, half as long as the tube which much exceeds the calyx: 

 ovules 2-several in each cell. Very variable, and a number of segregates have
