narrower and only half as large as in the precedhig : anthers in the throat, ohlong : ovules 

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

 — Plains of the Ui^per Platte and Columbia to Arizona and E. California. Widely varia- 

 ble. The original Cantua pum/ensi, Torr. Ann. Lye. N. Y. ii. 20 {^i^fjocldoa Torreyi, Don), of 

 the Platte, is a low glabrate form. 



Var. CSespitosa, Gray, i.e. {Leptodactylon ae.yntosum, Nutt. PI. Gamb.), is a low and 

 dense form, imitatmg P/i/o.r Do'.ujlasil in growth. — Scott's Bluffs, Wyoming, Nuttall. 



Var. Hookeri, Gray, l- c. (Phlox Hookeri, Dougl. in Hook. Fl. ii. 7o, t. 159, & G. 

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

 shoots. — Interior of Oregon, California, &c. Flowers not foimd 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 in Collomia) when wetted mucilaginous and sending out threads containing 

 each a spiral coil (sjiiricle), 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 of the mostly (some- 

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

 often laciniate or unequal : corolla slender, tubular-funnelform 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 tliem, more than once pinnately parted, i. e. their primary divisions 

 incised or parted. 



-f— 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 verv glandular-viscid and 

 unpleasantly aromatic-scented. 



G. squarrosa, Hook. & Arn. Bather 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 entire calyx-lobes. — Bot. Beech. 1-51 ; Gray, Proc. Am. Acad. 1. c. 269.

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

 Plains of California and Oregon ; a common fetid weed. 



-f— -I— Ovules varying from 1 to 2 or .3 to 4 in each cell : stamens exserted out of the throat of 

 the corolla, at length mostly eriualling the lobes : herbage less viscid or glandular, in some not 

 at all so. 



G. COtuleef olia, Steud. Eigid, a span to a foot liigh, 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 the ovavy. — yEgocMoa pubescens 

 & cotiilu'/olia, Benth. in Bot. Beg. Navarretia pubescens & cotula>foUa, Hook. & Arn. I. c. ; 

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

 mis Cotiila. 



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

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

 spincscent 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 interte.rta. Hook. 1. c. — 

 Plains of Columbia Eivcr to California and the Rocky Mountains. Corolla 3 or 4 lines 

 long, the stamens equalling its lobes.
