GILIA FAMILY. 335 



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 Chamise, Napa Valley. 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 frequently has the appearance of being 

 salverform and somewhat exserted. Distinct from L. filipes (Benth.) Greene, 

 common in the Sierra Nevada foothills, which has a turbinate calyx and a short 

 funnelform corolla with broad limb. 



4. L. ambiguus (Rattan) 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 obconic throat scarcely exceeded by the spreading lobes; limb bluish 

 purple, 4 lines broad; ovules 2 in each cell. — (Gilia ambigua Rattan.) 



Low hills: Santa Clara Valley and near Livermore. May. Some of the 

 flowers show a glandular black band % line in breadth midway of the calyx- 

 tube. 



5. L. rattanii (Gray) Greene. Ten to 12 in. high, glandular-hirsutulous 

 at the nodes and even the flowers with gland-tipped hairs; pedicels 1% in. long 

 or less; calyx cylindraceous, in anthesis 1 line long, accrescent in fruit to 2 

 lines long; corolla nearly salverform, with a long slender tube and short funnel- 

 form throat, the tube 3 to 5 lines long, exserted barely 1 line to exceeding 3 

 lines, the throat yellow, the limb blue and 3 to 5 lines broad; seeds small, very 

 rugulose, one to each cell or the third cell empty. — (Gilia rattanii Gray.) 



Santa Cruz Mts., Lake Co. June. Remarkable for the variable development 

 of the corolla-tube, even on the same plant. 



6. L. densiflorus Benth. Erect, simple, 5 in. to 2 ft. high; divisions of 

 the palmately divided leaves 5 to 11, linear-filiform and rigid, ciliate towards 

 the base and somewhat scabrous on the margins ; corolla lilac or white, 1 in. 

 long or less, its tube only equaling or little exceeding the obovate lobes, little 

 if at all exserted beyond the calyx-teeth, its limb % in. broad, more or less; 

 seeds 3 in each cell, strongly wrinkled. 



Coast Range valleys or higher hills, infrequent: Pt. Reyes; Alameda; Santa 

 Cruz Mts. ; Monterey Co. and southward. June. 



7. L. androsaceus (Benth.) Greene. Stoutish, usually simple, 7 to 11 or 

 15 in. high, finely tomentose or glabrate ; lowest leaves spatulate; bracts ciliate, 

 otherwise nearly glabrous; flowers usually many; corolla lilac, lavender, pink or 

 white, 1 in. long, much exceeding the bracts, the lobes 3 to 4 lines long, the 

 throat dark purple with yellow border, 1 line long; stamens little surpassing the 

 throat of the corolla. 



Common everywhere in the Coast Ranges and Sierra Nevada on low hills 

 and at middle altitudes. Apr. 



8. L. parviflorus (Benth.) Greene. Simple or with few branches from 

 the base, erect, commonly 3 to 6 or 11 in. high, almost glabrous; bracts sca- 

 brous or hirsutulous, not ciliate or scarcely so, commonly 3 or 4 lines long; 

 segments of the leaves obovate- or linear-spatulate; corolla purple, pinkish 

 or pale yellow, % to 1% in. long, the lobes oval, 2 to 3 lines long or less, 

 tinged with red or brown on the outside, the throat yellow; stamens half or 

 commonly more than half as long as the corolla-limb. — (Gilia micrantha Steud.) 



The nio^T common species, abundant in open ground in the hill country. It 



is one of the annuals which figure in the vernal landscape color effects in the 



often occupying extensive slopes of the lower or higher hills
