subtending the cymose cluster longer than the flowers : tube of the corolla hardly exceeding 



the anstulate-mucronate calyx-lobes: anthers in the throat, on very short filaments: 



ovules 2 m each cell. - Bot. Mex. Bound. 147 ; Watson, Bot. King, 268. - Western Texas 



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



§ 9. Ipomopsis, Benth., partly. Flowers thyrsoid-paniculate, inconspicuously 



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



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



subulate calyx-lobes and its own ovate or lanceolate spreading or recui-ving 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. Ipomeria, Nutt. 



* Stem virgate, leafy: leaves pinnately parted into filiform or narrowly linear divisions: inflores- 

 cence contracted. 



G. coronopifolia, Pers. (Standing Ctpeess.) Glabrous or barely pubescent: stem 

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

 acute and niucronate : 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: 

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

 short-pedunculate clusters : calyx coinmorily 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. 626; 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 peatly : 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, with stamens and style included. 



Var. Bridgesii, Gray, 1. c. ..-Stems low (6 to 18 inches) and diffuse or spreading, 

 as if from a perennial root : corolla bright red ; fts lobes oblong-ovate and merely acute : 

 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-puberulent, a span or two high : leaves all undivided, 

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

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

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

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

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

 short filaments : seeds developing mucilage and spiricles. — Gray, Proc. Am. Acad. viii. 276. 

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