Galpinsia camporum Wooton & Standley, sp. nov. 
Low perennial, 15 em. high, from a thick, woody base; stems very numerous, 
simple or branched, slender, flexuous, finely and densely villous, glandular; 
leaves very numerous, green, elliptic-lanceolate, 15 to 20 mm. long, acute, entire 
or nearly so, glandular-pubescent or glandular-puberulent; calyx tube 4 cm. 
long, slender, sparingly glandular or villous; sepals 12 mm. long, slightly villous, 
the free tips 2 mm. long; petals 12 to 18 mm. long, rounded-obovate; capsules 
cylindric, erect, 13 mm. long, soft-pubescent and glandular, 
Type in the U. 8. National Herbarium, no. 564592, collected at Knowles, July 
29, 1909, by E. O. Wooton. 
ADDITIONAL SPECIMENS EXAMINED: Highest point of the Llano Estacado, June 
17, 1903, Bailey 518; near Causey, August 17, 1909, Wooton; Buchanan, Au- 
gust 12, 1909, Wooton; Hondo Hill, July 28, 1905, Wooton; Nara Visa, October 
2, 1907, W. Belknap. 
The type was collected in sandy soil on the broad plains near Knowles. 
It is similar to Galpinsia greggii and G. lampsana. From the former it is dis- 
tinguished by its larger flowers and the different form of the leaves, and from 
the latter by its much smaller flowers and shorter, less abundant pubescence. 
Galpinsia lampsana (Buckl.) Wooton & Standley. 
Oenothera lampsana Buckl. Proc. Acad. Phila. 1861: 454. 1862. 
A common species of western Texas and eastern New Mexico. 
Gaura brassicacea Wooton & Standley, sp. nov. 
Stems numerous, slender, ascending, 90 em. high or less, purplish, densely 
hispid; basal leaves oblanceolate, 5 to 9 ecm. long, sinuate-toothed; cauline 
leaves oblong to oblanceolate, sessile, acutish or obtuse, deeply sinuate-dentate, 
abundantly hirsute, especially along the veins; branches of the inflorescence 
glabrous, slender; bracts broadly obovate, acuminate, short-ciliate; calyx 
glabrous; fruit glabrous, narrowly ovoid, sharply angled, short-stipitate, 8 to 
10 mm. long, acute: 
Type in the U. S. National Herbarium, no. 45764, collected at Socorro in 
May, 1881, by G. R. Vasey. Another specimen of the same collection is mounted 
on sheet 45763. 
Gaura cinerea Wooton & Standley, sp. nov. 
Probably tall and much branched; stems slender, ascending, covered. with a 
dense, loose, rather stiff pubescence; leaves elliptic or narrowly oblong, 20 to 
25 mm, long, abruptly acuminate with subulate tips, sessile, sinuate-serrate 
below the middle, covered with a dense, coarse, curled pubescence: branches 
of the inflorescence densely cinereous; bracts ovate-lanceolate, with attenuate, 
subulate tips, pubescent; calyx and ovary densely cinereous; fruit on a slender 
cinereous stipe as long as the body. 
Type in the U. 8S. National Herbarium, no. 382592, collected 20 miles south of 
Roswell, in August, 1900, by F. S. and Esther 8. Earle (no. 538). Altitude 
1,080 meters. 
We have also seen a specimen collected at Big Spring, Texas, in September, 
1881, by Dr. V. Havard. 
Both sheets are in poor condition, showing neither open flowers nor mature 
fruit, but the plants are so distinct that one can not hesitate to describe them. 
The only species with which to compare this is Gaura villosa, but in that the 
branches of the inflorescence are glabrous and the pubescence on the flowers 
and stems is of an entirely different kind.
