Gaura linearis Wooton & Standley, sp. nov. 
Stems slender, erect or ascending, branched, glabrous; leaves linear, bright 
green, entire, acute, sessile, 10 to 15 mm. long, numerous; branches of the in- 
florescence cinereous-puberulent among the flowers; bracts lanceolate or ovate, 
acuminate, usually less than half as long as the ovary; calyx tube 3 mm. long, 
strigose like the lobes; petals G or 7 mm. long, oblanceolate, obtuse, long- 
clawed; mature fruit not seen, but the ovary densely whitish-strigose. 
Type in the U, 8. National Herbarium, no. 564598, collected on gypsum soil 
near ‘Lakewood, August 6, 1909, by E. O. Wooton. 
Related to Gaura induta, but readily distinguished by the short, broad, acumi- 
nate bracts and narrow leaves. 
Gaura podocarpa Wooton & Standley, sp. nov. 
Stems slender, branched from the base and again above, erect, hirsute, red- 
dish; leaves narrowly oblanceolate or oblong, 4 to 6 cm. long, with a few low, 
repand teeth, acute, the uppermost leaves entire, linear, hirsute along the veins, 
ciliate; branches of the inflorescence glabrous; bracts ovate, acute, ciliolate; 
calyx tube glabrous, 5 mm. long; petals oblanceolate, obtuse, 6 or 7 mm long; 
fruit ovoid, 8 mm. long, acutish, very sharply angled, contracted into a short 
stipe below. 
Type in the U. 8. National Herbarium, no. 495277, collected by O. B. Metcalfe 
on Bear Mountain near Silver City, Grant County, June 17, 1903 (no. 166). 
Altitude 1,500 meters. 
ADDITIONAL SPECIMENS EXAMINED: West Fork of the Gila, alt. 2,040 meters, 
1903, Metcalfe 841; West Fork of the Gila, alt. 2,100 meters, August 6, 1900, 
Wooton; Van Pattens, August 29, 1894, Wooton; Filmore Canyon, October 29, 
1904, Wooton. 
The plant also occurs in the Huachuca Mountains of Arizona. 
This, with Gaura strigillosa, G. gracilis, and G. glandulosa, described here, has 
passed as G. suffulta Engelm., a plant originally described from Lindheimer’s 
collections. All four of our plants have much narrower leaves, broader and 
much shorter bracts, smaller flowers, and larger fruit; while each one, in addi- 
tion, differs from that species in other particulars. 
Gaura strigillosa Wooton & Standley, sp. nov. 
Stems slender, ascending, much branched, 60 em, high or less, reddish, hir- 
sute; leaves oblong or linear-oblong, or the uppermost linear, the larger ones 
sinuate-dentate, sessile, acutish, glabrous except for the short-hirsute mid- 
vein and ciliolate margins; branches of the inflorescence glabrous; bracts ovate 
or ovate-lanceolate, acute, strigillose, ciliolate; calyx strigillose, the tube 6 mm. 
long; petals G mm. long; fruit glabrous, narrowly ovoid, sharply angled, short- 
stipitate, 8 mm. long. 
Type in the U. 8. National Herbarium, no. 5610738, collected by E. O. Wooton 
at Wingfields Ranch on Ruidoso Creek in the White Mountains, July 8, 1895. 
Lavauxia hamata Wooton & Standley, sp. nov. 
Cespitose perennial with a short, thick stem 5 to 6 em. long; leaves narrowly 
elliptic-lanceolate, deeply and irregularly pinnatifid, the segments acute, attenu- 
ate, long-petioled, bright green, glabrous except along the puberulent margins; 
calyx tube 5 to 7 cm. long, slender, glabrous or nearly so, the lobes 15 to 20 mm. 
long, nearly glabrous; petals 2 cm. long; capsules 20 to 25 mm. long, 10 mm.
