Common in the Sierra Nevada at middle altitudes; occurring in the 

 Coast Ranges, at the higher altitudes, hut rarely collected (Mt. 

 Hamilton, acc. to Davy). July. 



2. C. heterophylla Hook. Plants low and erect, or diffusely 

 branching and the stems 1 ft. long; herbage more or less viscid- 

 pubescent; leaves thin, the upper entire or toothed, the lower pin- 

 nately cleft or pinnately divided and the broad segments laciniately 

 cleft; flowers in small bracted clusters at the ends of the branches; 

 corolla red-purple, small, 4 to 5 lines long, the limb 1 line broad; 

 capsule ellipsoid; seeds 2 or 3 in each cell. 



Shady places in the mountains: Coast Ranges (Marin Co., Napa 

 Co.); Sierra Nevada. Mar. -Apr. 



3. GILIA R. & P. 



Herbs, ours annuals except G. densifolia. Leaves alternate (except 

 G. gracilis), entire or pinnately toothed, lobed, or divided. Calyx- 

 tube scarious below the sinuses. Corolla funnelform to salverform, 

 blue, yellow, or white, the stamens equally inserted on its throat 

 except a few species. Capsule 3-celled and 3-valved, or (in 2 species 

 of the subgenus Navarretia) 1-celled and 4-valved. (Felipe Luis Gil, 

 Spanish botanist of the latter half of the 18th century.) 



Calyx-segments equal, entire; flowers solitary, in loose or capitate clusters, 

 or paniculate, bracted or bractless; stamens equally or unequally in- 

 serted on throat of corolla; leaves in ours mostly flaccid, not pungent or 

 prickly.— Subgenus Eugilia. 

 Leaves opposite and entire; corolla salverform, its tube little surpassing 



calyx, its throat yellow and limb purple 1. 6. gracilis. 



Leaves alternate. 



Leaves pinnatifid or pinnately lobed, the upper usually palmately 

 parted into 3 to 5 divisions ; corolla funnelform, its tube 2 to 3 times 

 longer than the calyx 2. G. gilioides. 



Leaves mostly 1 to 3 times pinnately dissected into narrow segments, not 

 pungent; flower-clusters not bracteate; calyx-teeth equal; corolla 

 funnelform. 



Stamens included ; flowers few in mostly loose clusters. 

 Flowers blue or purple; proper tube of corolla much shorter than 

 calyx; leaves pinnately parted into entire or toothed lobes. 



3. 0. mulUcaulis. 



Flowers 3-colored, blue, purple, and yellow: leaves laciniately 



bi pinnatifid 4. (r. tricolor. 



stamens more or less obviously exserted ; flowers in capitate clusters 

 terminating long peduncles. 



Corolla segments obovate or oblong 5. G. achillesefofia. 



Corolla segments nearly linear 6. G. capitata. 



Leaves or their simple divisions linear or filiform and rigid; flowers 

 crowded into capitate leafy-bracted clusters, the calyces and the 

 bracts densely woolly-matted; corolla salverform; stamens exserted. 

 Annual or biennial, not woody; var. floribunda of . 7. 0. virgata. 

 Woody-based perennial; corolla 6 to"8 lines long . 8. G. densifolia. 

 Calyx-segments mostly unequal, entire or some toothed or cleft; flowers in 

 terminal capitate bracted clusters; corolla tubular-funnelform or salver- 

 form, the stamens equally inserted upon it; leaves pinnatifid or the 

 lowest subentire, the segments mostly rigid and subulate or cuspidate. 

 —Subgenus Navarretia. 

 Capsule not regularly dehiscent, the walls thin and transparent and 

 closely covering the seeds which are agglutinated into a mass; flowers 

 white (pale blue in no. 11). 

 Steins erect or spreading.
