494 POLEMONIACE.E. Gilia. 



G. minima, Gray, a dwarf and tufted nearly glabrous white-flowered species, related to tins 

 and the next, inhabits the interior dry region, but has not been found west of Utah. 



21. Gr. Breweri, Gray. A span high, or less, at length much branched and dif- 

 fusely tufted, minutely glandular-puberulent throughout : divisions of the leaves 

 acerose and mostly entire : flowers in less dense leafy heads : corolla yellow, hardly 

 longer than the slender-subulate calyx-lobes ; the tube of the latter very short : 

 ovules and seeds mostly sobtary. — Proc. Am. Acad. viii. 269. 



Dry ground, in the Sierra Nevada, from Placer Co. to Sierra Co. at 6,000 to 8,000 feet (Brcicer, 

 Bola/nder), and through Nevada to Wyoming Territory. 



22. Gr. leucocephala, Gray, 1. c. A span high, rather slender, loosely branched, 

 not glandular, glabrous, except a little woolliness at summit and on the thin calyx- 

 tube : leaves soft, with commonly simple linear-filiform divisions ; those of the 

 bracts hardly pungent : heads dense : corolla white, longer than the calyx : ovules 

 2 in each cell. — Navarrelia leucocephala, Benth. PL Hartw. 324. 



Damp or low grounds, around San Francisco Bay to the Sacramento and Mendocino Co. 



+- +- Leaves only once pinnatifid or incised, or many of them entire, 



++ All slender and filiform, except the bracts of the small heads, which are more or less 

 palmately 3 — 5-cleft : corolla small (3 or 4 lines long), rather slender. 



23. Gr. divaricata, Torr. Diffusely branched, slender, a span or more in 

 height, somewhat pubescent, hardly at all glandular, the bracts and calyx more or 

 less woolly-pubescent : filiform branches proliferous : divisions of the uppermost 

 leaves and the similar bracts acerose : corolla purple or (apparently) yellowish : 

 ovules 5 to 7 in each cell. — Gray, Proc. Am. Acad. 1. c. 



Lake Co. to Mariposa Co. up to 8,000 feet. 



24. Gr. filicaulis, Torr. A span or two high, moderately or at length widely 

 branched, slender, viscid-glandular, especially above ; branches naked : upper leaves 

 filiform or setaceous and entire ; bracts somewhat cuneate and the lobes pungent, 

 the inner ones shorter than the violet corolla : ovules mostly solitary in each cell. — 

 Gray, Proc. Am. Acad. 1. c. 



Mariposa Co. to Butte Co., Jcffray, Torrey, Mrs. Pulsifcr Ames. 



++ 4-i- Leaves broader, rigid, linear or lanceolate, and with spinulose lobes: stems stout: 

 flowers densely glomerate : corolla violet or purple, barely half an inch long; about 

 twice the length of the pungent calyx-lobes. 



25. Gr. viscidula, Gray, 1. c. A span high, or less, at length much branched, 

 viscid-pubescent : cauline leaves npstly slender and laciniate-pinnatifid ; the as- 

 cending lobes acerose or subulate ; floral ones broader and more spinescent ; bracts 

 more dilated at base and palmately cleft : ovules 1 to 4 in each cell. — Navarretia 

 viscidula, Benth. PI. Hartw. 325, a small form. 



Dry hills, Santa Barbara to San Francisco, &c, and to the Sierra Nevada. 



26. Gr. atractyloides, Steudel. A span high, simple or much branched, viscid- 

 pubescent, very rigid, especially the foliage : cauline leaves lanceolate, the upper 

 becoming broader and the floral ovate, all pinnatifid, with widely spreading subulate 

 spine-like lobes : leafy heads rather few-flowered : ovules 6 or 7 in each cell. 



Open dry ground, from San Diego to Santa Cruz. Leaves, at least the floral ones, almost carti- 

 laginous. 



-J--;- ++ ++ Leaves dilated towards the apex, at least the upper ones : stems depressed : 

 flowers proportionally large, less crowded. 



27. Gr. setosissima, Gray, 1. c. An inch or two high, at length forming a 

 depressed tuft, cinereous-pubescent or glabrate : lower leaves linear and slightly 

 toothed, the upper becoming oblanceolate, spatulate, or with a cuneate 3-lobed
