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

 spreading or squarrose-recurved. 



High and dry parts of the Siena Nevada (common above the Yosemite Valley), and through 

 the interior of Oregon, to the Kocky Mountains ; tlie var. squarrosa, from the western bordcra of 

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

 species. 



in. All or nil hut (he lowest leaves alternate and more or less jjinnately compound, 

 cleft, or toothed, or rarebj quite entire. {Seed-coat when welted usually develop- 

 ing spiral threads as ivell as mucilage.) 



§ 6. Floivers capitate-glomerate or at least densely clustered, leafy-hracted: bracts and 

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

 tuhular-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 viscid-pubescent or glandular, never 

 white-woolly, with once or ttvice pinnatifid 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 /o 12 in each cell. 



18. G. squarrosa, Hook. Sc Arn. Eigid, 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.

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 /'o 5 lines long. 



-J- Leaves twice pinnatifid, at least the loiver ones : ovules \ to i in each cell. 



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

 tomentose-puberuleut, or above villous-pubcscent and minutely glandular : most "of 

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

 upper and the bracts spinescent : tubo of the violet or whitish corolla hardly longer 

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

 l-8oedod. — Navarretia pubescens & N. cotnhvfolta, \\m\,\\. 



Dry hillsides, conunon tiirough the western part of the State and in the foot-hills of the Sierm 

 ^evada. Exhales the odor of Anthanis Cotula. 



20. G. intertexta, Rteudol. At length diffusely much branched, a span high, 

 neither viscid nor glandular: stems retror.sely pubescent: leaves mainly globrovis ; 

 their divaricate acerose and spinescent divisions cither sparingly divided" or simple : 

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

 villous with long s])reading hairs : corolla white, little exceeding the calyx : ovules 

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