494 POLEMONIACE^E. Gilia. 



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

 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 solitary. Proc. Am. Acad. viii. 269. 



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

 Bolandcr), and through Nevada to Wyoming Territory. 



22. G-. 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. Navarretia leucocephala, Bentli. PL Hartw. 324. 



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



-t- -t- 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., Jeffray, Torrey, Mrs. Pulsifer Ames. 



++ ++ 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 mostly 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. 



-n- ++ ++ 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 oblauceolate, spatulate, or with a cuneate 3-lobed
