narrower and only half as large aa in the preceding : anthers in the throat, oblong : ovules 

 8 or 10 in each cell. — Proc. Am. Acad. 1. c. G. pungens & G. Hookeri, Benth. in DC. 1. c. 

 — Plains of the Upper Platte and Columbia to Arizona and E. California. Widely varia- 

 ble. The original Cantua -pungens, Torr. Ann. Lye. N. Y. ii. 26 {^gochloa Torreyi, Don), of 

 the Platte, is a low glabrate form. 



Var. caespitosa, Gray, i.e. (Leptodactylm cceapitosum, Nutt. PI. Gamb.),i8 a low and 

 dense form, imitating Phlox Douglasii in growth. — Scott's Bluffs, Wyoming, Nuttnll. 



Var. Hookeri, Gray, l. c. [Phlox Hookeri, Dougl. in Hook. Fl. ii. 73, t. 159, & G. 

 Hookeri, Benth.), is taller, with sparser more rigid leaves, and viscid-pubescent flowering 

 shoots. — Interior of Oregon, California, &c. Flowers not found to be " yellow." 



Var. squarrosa, Gray, 1. c. A foot or two high, with virgate branches, beset with 

 stouter and more rigid recurved-spreading pungent leaves. — Dry interior region, Nevada 

 to Idaho and Washington Terr. 



Series II. Leaves alternate and pinnately incised, cleft, or divided, or rarely- 

 entire, occasionally some of the lowermost opposite : filaments slender : seed-coat 

 (as m.Collomia) when wetted mucilaginous and sending out threads containing 

 each a spiral coil (spiricle), except in a few species. 



§ 6. Navarretia, Gray, 1. c. Flowers capitate-crowded and densely foliaceous- 

 bracted (in the last species less so) : lobes of the calyx and oi the mostly (some- 

 times nearly palmately) multifid bracts rigid and acerose-pungent or spinulose, 

 often laciniate or unequal : corolla slender, tubular-funuelform or almost salver- 

 form, and with rather small oval or oblong lobes : filaments inserted in or below 

 the throat : anthers short : stigmas and cells of the ovary sometimes reduced to 2 : 

 low and much-branching annuals, sometimes glandular-viscid, never white-woolly ; 

 with chiefly 1-2-pinnately divided or cleft leaves, their lobes commonly subulate 

 and pungent. — Navarretia, Ruiz & Pav,, Benth. 



* Leaves and bracts, or some of them, more than once pinnately parted, i. e. their primary divisions 

 incised or parted. 



H— Ovules and seeds numerous (8 to 12) in each cell: stamens included in the throat of the corolla, 

 commonly unequal in length and slightly so in insertion : herbage very glandular-viscid and 

 unpleasantly aromatic-scented. 



G. squarrosa, Hook. & Arn. Rather stout and rigid, often a foot high : upper leaves 

 and bracts spinescent: tube of the small blue (or sometimes whitish) corolla rather shorter 

 than the mostly enth-e calyx-lobes. — Bot. Beech. 151; Gray, Proc. Am. Acad. 1. e. 269.

 Bot. Reg. 1. c. Navarretia squarrosa. Hook. & Arn. 1. c. 368. N. pungens, Hook. FI. ii. 75. 

 Plains of California and Oregon ; a common fetid weed. 



•i- +- Ovules varying from 1 to 2 or 3 to 4 in each cell : stamens exserted out of the throat of 

 the corolla, at leng-th mostly equalling the lobes : herbage less viscid or glandular, in some not 

 at all so. 



G. cotlllsef olia, Steud. Rigid, a span to a foot high, pubescent or below glabrate, above 

 mostly minutely glandular : leaves chiefly 2-pinnately parted ; the subulate divisions of the 

 upper and of the bracts spinescent : tube of the violet-blue or white corolla hardly longer 

 than the lobes of the sparsely villous calyx ; the throat f unnelform : ovules solitary 

 or rarely a pair in each of the (frequently only 2) cells of tlie ovary. — ^gocMoa pubescens 

 & cotula/olia, Benth. in Bot. Reg. Navarretia puhescens & cotulcefolia, Hook. & Arn. 1. c. ; 

 Benth. in DC. 1. c. — California; common westward, on dry hiUs : exhales the odor of Anthc- 

 mis Cotula. 



G. intertexta, Steud. Erect or widely branched, low and rather stout, neither viscid 

 nor glandular: stem retrorsely pubescent: leaves mainly glabrous, with divaricate acerose- 

 spinescent divisions sparingly divided or simple : flowers densely glomerate : tube of the 

 calyx and base of the bracts strongly villous with white spreading hairs ; its lobes equalling 

 the white corolla : ovules and seeds 3 or 4 in each cell. — Navarretia intertexta, Hook. I. c. — 

 Plains of Columbia River to California and tlie Rocky Mountains. Corolla 3 or 4 lines 

 long, the stamens equalling its lobes.
