GILTA FAMILY. 329 



leaves in a dense tuft; leaflets numerous and crowded, palmately 3 to 5-parted 



into small divisions; flowers capitate or spieate; corolla blue (or white), 9 

 to 10 lines long. — Rocky summits of the high peaks of the Sierra Nevada. 



2. COLLOMIA Nntt. 



Herbs, ours annuals with alternate leaves. Flowers in ours in dense clusters 

 with foliaceous bracts. Calyx turbinate, in age obpyramidal or cup-shaped, 

 its teeth or lobes equal, entire, erect, the sinuses in age distended into a re- 

 curved lobe. Corolla narrowly funnelform or salverform, salmon-yellow, red- 

 dish, purple, or white. Stamens unequal and unequally inserted on the tube 

 of the corolla, mostly straight. Seed 1 in each cell, the seed-coat developing 

 spiral threads when wet. Capsule oval to obovoid. (Greek kolla, glue, on ac- 

 count of the mucilaginous seeds.) 



Corona narrowly funnelform. pale salmon-color; leaves entire 1. C. grandiflora. 



Corolla salverform. red-purple; leaves more or less bipinnatifid or simply toothed or 

 entire 2. C. heterophylla. 



1. C. grandiflora Dougl. Erect, simple, % to 2 ft. high; leaves alternate, 

 linear or oblong-lanceolate, entire, sessile; flowers crowded in head-like clusters 

 at the ends of the stems and leafy-bracted, or some often borne below, either 

 singly in the axils or in small clusters on short branchlets; calyx-tube obconical, 

 its lobes broad and obtuse; corolla pale salmon-color, narrowly funnelform, 

 1 in. long, its tube thrice as long as the calyx, its lobes broadly oblong; valves 

 of the capsule after dehiscence with the sides strongly reflexed. 



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

 Ranges at the higher altitudes, but rarely collected. July. 



2. C. heterophylla Hook. 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 pinnately 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 (Gilroy, Marin Co., Napa Co.) ; 

 Sierra Nevada. Mar.-Apr, 



3. GILIA R, & P. 

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

 gracilis), pinnately toothed, lobed, or divided, or sometimes entire. 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.) 



A. Calyx-segments equal, entire. 

 Flowers solitary, in loose or capitate clusters, or paniculate, bracted or bractless; stamens 

 equally or unequally inserted on throat of corolla; leaves in ours mostly flaccid, not 

 pungent or prickly. — Subgenus Eugilia. 



1. Leaves opposite. 



Leaves entire; corolla salverform, its tube little surpassing calyx, its throat yellow and 

 limb purple 1. G. gracilis. 



2. 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.
