subtending the cj-mose cluster longer than the flowers : tube of the corolla hardly exceeding 

 the aristulate-niucronate calyx-lobes: anthers in the throat, on very sliort filaments: 

 ovules 2 in each cell. — Bot. Mex. Bound. 147 ; Watson, Bot. King, 208. — Western Texas 

 to Utah and W. Nevada. Corolla a line or two long, white with a tinge of rose-color. 



§ 9. Ii'OMOPSis, Benth., partly. F'lowers thyrsoid-paniculate, inconspicuously 



bracted or ebracteate : corolla scarlet or red, with white varieties, narrowly tuhular- 



fimnelform, gradually and regularly enlarging upward, very much surpassing the 



subulate calyx-lobes and its own ovate or lanceolate spreading or recurving lobes: 



stamens inserted in the throat or below the sinuses of the corolla, not longer than 



its lobes : anthers oval or short-oblong : ovules numerous : biennials, not woolly, 



and usually showy-flowered. — Ipomopsis, Michx. Ipoineria, Nutt. 



* Stem virgate, leafy: leaves pinnatfly [jarted into lilifonii or narrowly linear divisions : inflores- 

 cence contracted. 



G. COronopifolia, Pers. (Standing Cypress.) Glabrous or barely pubescent : stem 

 2 to 6 feet higii, very leafy througliout : divisions of the leaves and rhachis nearly filiform, 

 acute and nuicronate : flowers very numerous in a long and narrow compact thyrsus or 

 panicle, inodorous : calyx-lobes setaceous-subulate, as long as the tube : corolla an inch or an 

 inch and a half long, scarlet (within yellowish and dotted with red) ; the lobes ovate, mode- 

 rately spreading, barely exceeding the slender filaments : seeds not developing mucilage 

 nor spiral threads when wet, but with a lax reticulate-cellular outer coat! — Lindl. Bot.

G. aggregata, Spreng. Somewhat pubescent : stems 2 to 4 feet high, less leafy, some- 

 times loosely branching: leaves thickish, with narrowly linear mucronulate divisions: 

 thyrsoid narrow panicle loose or interrupted ; the (fragrant) flowers sessile in small mostly 

 short-pedunculate clusters : calyx commonly glandular ; its lobes subulate : corolla from 

 scarlet to pink-red (rarely white), with narrow tube ; the lobes ovate or lanceolate, acute or 

 acuminate, widely spreading, soon recurved : filaments slender : seeds when wetted devel- 

 oping mucilage and spiricles. — Syst. i. 020 ; Don, Brit. Fl. Gard. ser. 2, t. 218 ; Gray, 1. c.

 in Hook. Fl. ii. 74; Benth. 1. c. — W. Nebraska to W. Texas, New Mexico to Oregon, E. 

 California and Arizona. (Adjacent Mex.) More or less heterogone-dimorphous : both 

 stamens and style included (and the style shorter) in some individuals, both exserted (and 

 the style longer) in most. Varies greatly : the extremes being 



Var. attenuata. Corolla-lobes lanceolate, tapering gradually from the very base 

 into a slender acumination : calyx-lobes equally slender. — Colorado, in Middle Park, Parry. 

 A white-flowered form, witii stamens and style included. 



Var. Bridgesii, Gray, 1. c. Stems low (0 to 18 inches) and diffuse *or spreading, 

 as if from a perennial root : corolla bright red ; its lobes oblong-ovate and merely a(;ute : 

 calyx-lobes shorter and broader, from subulate-lanceolate to deltoid : lobes of the leaves 

 thicker and obtuse. — California, through the Sierra Nevada. 



* * Stem low, loosely paniculate-branched: upper leaves reduced to bracts. 



G. SUbnuda, Torr. Glandular-pubcrulcnt, a span or two high : leaves all undivided, 

 mainly crowded at the indurated base, spatulate or oblong aiul tapering into a margined 

 petiole, sparsely and irregidarly dentate; the few upper linear and entire; the uppermost 

 subulate and minute : flowers rather crowded in a few small clusters : calyx-lobes subulate, 

 about the length of the campanulate tube: corolla orange or scarlet; the tube (half inch 

 long) tlirice the length of the ovate obtuse lobes : anthers included in the throat on very 

 short filauients : seeds developing mucilage and spiricles. — Gray, Proc. Am. Acad. viii. 270. 

 — Arizona and S. Nevada to New Mexico, Newberry, Stretch, Palmer. 



G. Haydeni, Gray. Almost glabrous, above slightly glandular, a span or more high,
