y 



Lobes of the corolla 1 line long; flowers golden yellow 



9. L. acicularis. 

 Lobes of the corolla 1 to 1^ lines long; flowers purplish or pinkish . 



10. L. bicolor. 

 Corolla commonly not exceeding the bracts; bractlets conspicuously 

 hirsute-ciliate; rigid .plant . . .... 11. i. ciliatus. 



1. L. dichotomus Betith. Evening Snow. Erect, simple or 

 branching from near the base, 5 to'9 in. high; nodes few and inter- 

 nodes very long, twice to many times as long as the leaves; flowers 

 terminal or sessile in the forks; ribs of the calyx prolonged into linear- 

 acerose teeth; corolla salverform, white or nearly so, its tube equal- 

 ing the calyz-tube, its lobes strongly convolute in the bud, broadly 

 obovate, erose, the limb 1 in. broad; filaments at the very base 

 enlarged, somewhat winged and more or less hairy; cells of capsule 

 many-seeded; seeds not mucilaginous when wet. — (Gllia dichotoma 

 Benth.) 



Common on open slopes, mostly on high hills: Coast Eanges; Sierra 

 Foothills; San Joaquin plains; Southern California. Mar. -May. 



2. L. liniflorus (Benth.) G-reene. One ft. high or somewhat more, 

 mostly branching above; leaf-segments J to 1 in. long; flowers white, 

 on slender pedicels J to IJ in. long, in a diffuse panicle; corolla with 

 nearly obsolete tube; limb rotate, j to f in. broad, the obovate lobes 

 naked, with several blue longitudinal lines or veinlets; stamens J as 

 long as corolla-lobes; fllaments with a densely pilose ring just above 

 the base, the corolla pubescent at their insertion; ovules 6 to 8 in 

 each cell. — (Gilia liniflora Benth.) 



Plains and foothills: Solano Co. ; Stockton; San Mateo Co.; Loma 

 Prieta and southward to Southern California. May-June. 



3. L. pusillus (Benth.) Greene. Very slender, 3 to 6 in. high; 

 calyx cylindraceous, 1 to IJ lines long, its teeth as long as the tube; 

 corolla narrowly funnelform or subsalverform , its tube dilated some- 

 what above the middle, not exserted from the calyx or very slightly, 

 the lobes seldom exceeding the calyx-lobes, the limb 2 lines broad. — 

 (Gilia pusilla Benth.) 



Dry hillsides in Chamisal, Napa Valley, June 2, 1896. The corolla 

 after flowering is promptly pushed up by the rapidly growing capsule 

 and the tube contracts in withering, so that the corolla in age fre- 

 quently has the appearance of being salverform and somewhat 

 exserted. Distinct from L. filipes Greene, common in the Sierra 

 Eoothills, which has a turbinate calyx and a short-funnelform corolla 

 with broad limb. L. Bolandbri Greene is, perhaps, but a variety. 

 It was iirst collected at Ukiah by Bolander. Gray's herbarium seems 

 to indicate that his attributing the plant to Sonoma Co. was an inad- 

 vertence; however, it is not unlikely that it may be found south of 

 Mendocino Co. 



4. L. ambiguus (Eattan) Greene. Mostly 3 or 4 in. high; pedicels 

 about 6 lines long; corolla 4 to 6 lines long, nearly 3 times the length 

 of the calyx, not strictly salverform, its tube somewhat or not at all 

 exserted, its brown-purple obeonic throat scarcely exceeded by the
