Gilia. POLEMONIACE^E. 493 



1 7. Gr. pungens, Benth. 1. c. A span to a foot or so in height, bushy : more or 

 less viscid-pubescent, or nearly glabrous : rigid leaves little spreading or erect : 

 corolla white or rose-color ; the lobes narrower and only half as large as in the pre- 

 ceding : anthers borne in the throat, oblong : ovules 8 or 10 in each cell. Gray, 

 1. c. 268. G. pungens & G. Hookeri, Benth. in DC. Cantua pungens, Torr. Ann. 

 Lye. K Y. ii. 221. Phlox Hookeri, Dougl. in Hook. Fl. t. 159. 



Var. squarrosa, Gray, 1. c. : subulate divisions of the leaves stouter and soon 

 spreading or squarrose-recurved. 



Higli and dry parts of the Sierra Nevada (common above the Yosemite Valley), and through 

 the interior of Oregon, to the Rocky Mountains ; the var. squarrosa, from the western borders of 

 Nevada, through the dry interior. Probably Douglas mistook in assigning yellow flowers to this 

 species. 



III. All or all but the lowest leaves alternate and more or less pinnately compound, 

 cleft, or toothed, or rarely quite entire. (Seed-coat when wetted usually develop- 

 ing spiral threads as ivell as mucilage.} 



6. Flowers capitate-glomerate or at least densely clustered, leafy-bracted: bracts and 

 calyx-lobes often laciniate, rigid-acerose or spinulose-tipped. Corolla slender, 

 tubular-funnelform or almost salverform, and with small oblong lobes : fila- 

 ments inserted in or below the throat : anthers short : cells of the ovary and 

 stigmas sometimes only 2 : annuals, mostly viscul-pubescent or glandular, never 

 white-woolly, with once or twice pinnatijid or incised leaves, their lobes com- 

 monly pungent : the bracts sometimes palmately rather than pinnately cleft. 

 NAVARRETIA, Gray. (Navarretia, Euiz & Pav.) 



* Stamens included in the throat of the corolla : ovules 8 to 1 2 in each cell. 



18. Gr. squarrosa, Hook. & Am. Rigid, rather stout, becoming much branched, 

 very glandular-viscid, fetid : leaves twice pinnatifid, or pinnately parted and the 

 divisions either parted or incised : upper leaves and bracts spinescent : corolla blue, 

 rarely whitish, 4 or 5 lines long, rather shorter than the usually entire calyx-lobes : 

 stamens unequal in length and slightly so in insertion. G. pungens, Hook. Bot. 

 Mag. t. 2977. Hoitzia squarrosa, Eschsch. in Mem. Acad. Petrop. 1826, 283. 

 Navarretia squarrosa, Hook. & Am. Bot. Beechey, 368 ; Benth. in DC. Prodr, 1. c. 

 N. pungens, Hook. FL ii. 75. 



Open ground, common through the western part of the State and in the foot-hills, extending to 

 Oregon. 



* * Stamens more or less exserted : corolla slender, 3 to 5 lines long. 

 +- Leaves twice pinnatijid, at least the lower ones : ovules 1 to 4 in each cell. 



19. G. cotulaefolia, Steudel. Rather stout and rigid, a span to a foot high, 

 tomentose-puberulent, or above villous-pubescent and minutely glandular : most of 

 the leaves twice pinnately divided or parted into slender-subulate divisions ; the 

 upper and the bracts spinesceut : tube of the violet or whitish corolla hardly longer 

 than the sparsely villous calyx: ovules 1 or 2 in each cell: capsule usually only 

 1-seeded. Navarretia pubescens & N. cotulaefolia, Benth. 



^ Dry hillsides, common through the western part of the State and in the foot-hills of the Sierra 

 Nevada. Exhales the odor of Anthemis Cotula. 



20. Gr. intertexta, Steudel. At length diffusely much branched, a span high, 

 neither viscid nor glandular : stems retrorsely pubescent : leaves mainly glabrous ; 

 their divaricate acerose and spinescent divisions either sparingly divided or simple : 

 flowers densely glomerate : base of the bracts and tube of the calyx densely white- 

 villous with long spreading hairs : corolla white, little exceeding the calyx : ovules 

 and seeds 3 or 4 in each cell. Navarretia intertexta, Hook. Fl. ii. 75. 



Dry hills, from near San Francisco to Sierra Co., and north to Washington Territory.
