G. minima, Gray. Depressed, often forming broad tufts (half inch to 2 inches liigh), 

 ,glabrate : leaves aoicular and with simpler and fewer divisions than the preceding : tube of 

 the calyx white-hairy in the broad sinuses, as long as the unequal lobes, which equal or 

 exceed the white corolla : ovules 1 to 3 in each cell. — Proc. Am. Acad. 1. c. ; Waitson, Bot. 

 King, 266. Navarretia minima, Nutt. PI. Gamb. 160. — Interior of Oregon and Nevada to 

 Colorado and Dakota, in very arid districts. Corolla a line and a half long; the .stamens 

 mostly shorter than its lobes. 



G. Breweri,' Gray. Erect or at length much branched and diffusely spreading, an inch 

 to a span high, very minutely glandular-puberulent all over: flowers less -glomerate: 

 leaves with mostly simple acicular-subulate divisions : calyx-lobes similar to these, narrowly 

 subulate, about equalling the yellow corolla, 3 or 4 times the length of the .tulxe .(Which is 

 even shorter than the capsule) : ovules 1 or 2 in each cell. — Proc. Am. Aoad. 1. c. & Bot. 

 Calif, i. 494; Watson, 1. c. — Sierra Nevada, California (Brewer, &c), and through the in- 

 terior to Utah and Wyoming. Corolla 3 or 4 lines long. 



G. leuoooephala, Gray, 1. c. Slender, a span or less higb, seldom rigid, not glandular, 

 glabrous, except some woolly pubescence at the summit of the stem and of the thin calyx- 

 tube : leaves soft ; their often simple divisions islender ; those of the bracts barely pungent : 

 corolla white, longer than the calyx (4 lines long) : stamens considerably exserted: ovules 

 2 in each cell. — Navarretia leucocephala, Benth. PI. Hartw. 324. — California, on the Sacra- 

 mento and its tributaries, and Mendocino Co., in low grounds. 



# # Leaves simply pinnatifid or ineised, or many of them entire. 



-1— All slender and filiform, except the bracts of the small head*, which are more or less pahnately 

 3-5-cleft : corolla rather slender, 3 or 4 lines long : stems slender, not over a span high, diffusely 

 branched: often with proliferous filiform branches. 



G. divaricata, Torr. Not glandular-viscid, glabrate; the bracts and especially the 

 calyx woolly-pubescent : 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, viii 270, & Bot. Calif, i. 494. — California, from Lake Co. to Mariposa Co, up to 3000 

 feet in the Sierra Nevada. 



G. filicalSlis, Torr. More paniculate, glandular-viscid but not pubescent : upper leaves 

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

 shorter than the violet corolla : ovules solitary or at most a pair in each cell. — Gray, 1. c. 

 — California, Mariposa Co. to Butte Co. 



+- +- Leaves broader and rigid, linear or lanceolate, with spinutose lobes ; the floral ones dilated 

 at base and often cartilaginous : stems stout, 2 to 8 inches high: flowers densely glomerate: 

 corolla violet or purple, a third to half inch long, about twice the length of the subulate spinescent 

 calyx-lobes. 



G. visoidula, Gray, I.e. Viscid-pubeseent, at length much branched: canline leaves slen- 

 der and laciniate-pinnatifld or parted into setaceous-subulate ascending lobes ; the floral and 

 bracts only moderately dilated : ovules 1 to 4 in each cell. — Navarretia viscidvla, Benth. PI. 

 Hartw. 325, a small form. — Dry hills, California, from Santa Barbara to the Sacramento 

 and east to the foothills of the Sierra Nevada. 



G. atractyloides, Steud. Pubescent and very viscid, also very rigid, especially the 

 leaves and bracts ; these lanceolate or the uppermost even ovate, all pinnatifid, and witli 

 divaricate subulate-spinescent lobes : flowers less glomerate : ovules 6 or 7 in each cell. — 

 yEgochloa atractyloides, Benth. in Bot. Reg. 1. c. Navarretia atractyloides, Hook. & Arn. Bot. 

 Beech. 368 ; Benth. in DC. Prodr. ix. 310. — California, from Santa Cruz to San Diego Co., 

 in open and dry ground. 



H — M — n — Depressed, an inch or two high, at length prostrate, hardly if at all viscid : leaves up- 

 wardly dilated : flowers comparatively loose and scattered: corolla half to two thirds inch long, 

 tubular-funnelform, much exceeding the calyx. 



G. setosissima, Gray. Pubescent or glabrate, strikingly setose ; the very long white 

 bristles terminating the lobes of the calyx and the 3 to 7 lobes or teeth of the narrowly 

 cuneate or linear leaves, and scattered or sometimes clustered down their sides : corolla 

 white, purple, or mottled: the limb slightly irregular: ovules 3 to 10 in each cell. — Proc. 

 Am . Acad. 1. c, 271, & Bot. Calif. 494. Navarretia setosissima, Torr. & Gray, Bot. Ives 

 Colorad. 22. N. Schottii, Torr. Mex. Bound. 145 ( G. Schottii, Watson, Bot. King) ; an early 

 and depauperate form. — Deserts of S. B. California, to W. Arizona and S. Utah, first col-
