especially at base, or the lower lyrately pinnatifid: calyx-tube as long as the ovary: 
petals white, large, obcordate.—From Indian Territory to the lower Rio Grande and 
westward beyond the Pecos, 
13. GE. tetraptera Cav. Very near the last, but always more or less villous, with 
the capsule larger and more broadly winged and more abruptly contracted at top, 
the capsule with its pedicel often 2.5 to 3.5 em. long: calyx-tube usually shorter in 
proportion to the ovary.—A Mexican species reported from the San Antonio and 
lower Rio Grande valleys (Havard). 
14. GE. rosea Ait. Puberulent or sometimes villous, the stems ascending, 3 to 6 
dm. high, branching from the base : leaves lanceolate, 2.5 to 5 cm. long, acute or acumi- 
nate, attenuate to a petiole, repandly denticulate or entire, frequently sinuate-pinnati- 
fid toward tbe base : calyx-tube shorter than the ovary : petals purple, small, entire.— 
In the lower Rio Grande region of extreme southeastern Texas. Var. PARVIFOLIA 
Coulter is low and diffusely branching, 7.5 to 15 cm. high and villous, with leaves 
very much smaller, seldom 12 mm. long, and purple calyx.—Limpia canon (Nealley). 
The red-purple of the calyx and the lilac-purple of the corolla give a fuchsia-like 
look to the flowers.

large and rigid. 
15. GH. primiveris Gray. Often very small, more or less villous with spreading 
substrigose hairs: leaves 2.5 to 10 cm. long, lyrate-pinnatifid or the lower oblanceo- 
late and entire, narrowed into a petiole: calyx-tube 2.5 to 5 em. long: petals 8 to 
18 mm. long: capsule ovoid-conical, not crested, scarcely angled, net-veined.—Ex- 
treme western Texas beyond the Pecos, and extending into New Mexico. 
16. CE. triloba Nutt. Very rarely with a short stem, glabrous: leaves 10 to 50 cm. 
long, somewhat ciliate, long-petioled, runcinate pinnatifid or oblanceolate and only 
sinuately toothed, the segments usually repandly denticulate: calyx-tips free, the 
tube 5 to 10 em. long: petals 12 to 25 mm. long: ca, sule ovate, persistent, strongly 
winged, net-veined.—Throughout central and western Texas, 
17. CE. brachycarpa Gray. Pubescence canescent, short, usually dense, subto- 
mentose: leaves rather thick, ovate to linear-lanceolate, 7.5 to 20 cm. long, long- 
petioled, usually lyrately pinnatifid, the lower (or sometimes all) entire or more or 
less deeply sinuate-toothed: calyx-tube 5 to 10 cm. long: petals 3.5 em. long, 
purplish: capsule ovate, winged, more or less corky, smooth. (Incl. G2. Wrightii 
Gray.)—In the mountains west of the Pecos. 
»*** * Caulescent: flowers axillary, yellow: calyx slightly dilated : capsule ovate to 
orbicular, strongly angled or broadly winged. 
18. GS. Havardi Watson, Numerous short slender simple or branching stems rising 
from a branching caudex: canescent with short close pubescence: leaves linear- 
lanceolate, attenuate at each end, irregularly sinuate-pinnatifid, 1 to 5 cm. long: 
flowers sessile, erect in bud: calyx-tube 3.5 to 5 em. long, the attenuate tips coherent: 
petals orange-yellow turning red, 12 to 24 mm. long: capsule oblong-ovate, 4-angled 
and the valves strongly ribbed.—“ Prairies near Morfa, western Texas” (Havard). 
19. CE. Missouriensis Sims. Stems decumbent or ascending, simple or somewhat 
branched, very short or 3 dm. or more long and subwoody at base: pubescence 
canescent, short and silky, closely appressed, sometimes dense or wholly wanting: 
leaves thick, oval to linear, mostly narrowly lanceolate, 5 to 12.5 em. long, acuminate, 
attenuate to a usually slender petiole, entire or repand-denticulate: calyx-tube 5 to 
12.5 cm. long, the slender tips free: petals 2.5 to 6.5 cm. long: capsule 2.5 to 7.5 em.
