SAXTIFRAGACEAE, 
Heuchera pulchella Wooton & Standley, sp. nov. 
Acaulescent, with a very thick rootstock; flowering branches scapiform, 
naked, 7 to 10 em. high, minutely glandular; leaf blades cordate, 13 mm. wide 
or less, rather deeply lobed, the teeth broadly ovate, acuminate, bristle-tipped ; 
blades glabrous above, glandular beneath, bright green, ciliate; inflorescence 
secund, dense, most of the flowers solitary but occasionally two together ; hypan- 
thium densely glandular, slightly villous, campanulate, together with the oblong, 
obtuse sepals 4 mm. long; sepals purplish; petals linear-filiform, not surpassing 
the sepals; stamens slightly exceeding the sepals, 
Type in the U. 8. National Herbarium, no. 690250, collected from crevices of 
rocks on the summit of the Sandia Mountains, August 4, 1910, by E. O. Wooton. 
Another sheet in the National Herbarium was collected in New Mexico in 1869 
by Dr. Edward Palmer. 
This is nearest H, nana, but has a larger hypanthium and calyx, a more 
densely glandular hypanthium, a brighter colored calyx, shorter petals, and a 
denser inflorescence; the ciliw of the leaf margins, too, are much shorter and 
fewer. 
ROSACEAE. 
Oreobatus rubicundus Wooton & Standley, sp. nov. 
Shrub about 1 meter high, with spreading branches; stems slender, the bark 
soon exfoliating in thin layers; young branches reddish, very finely and closely 
pubescent ; leaves 30 to 40 mm. long and about as wide, round-ovate in outline, 
cordate at the base or truncate, the sinus always broad and open, conspicuously 
3-lobed, the lobes obtuse and often again lobed, crenate-dentate, the teeth ovate, 
usually obtuse and abruptly acuminate, glabrous above or nearly so, sparingly 
pubescent beneath along the veins, thin, bright green, the veins inconspicuous 
and scarcely reticulate; petioles slender, as long as the blades or considerably 
shorter, finely pubescent, reddish; peduncles solitary, short, 5 to 15 mm. long, 
stout, finely pubescent and glandular; sepals at anthesis about 10 mm. long, 
lanceolate, acuminate, in age becoming 15 mm. long and ov ate, with long, linear 
tips, finely pubescent on both surfaces, with numerous reddish glands on the 
outer face; petals white, fugacious, 10 to 15 mm. long, broadly oblong; fruit

Type in the U. S. National Herbarium, no, 560937, collected at Van Pattens 
Camp in the Organ Mountains, June 9, 1906, by Paul C. Standley. The shrubs 
are found in the Upper Sonoran Zone on the faces of cliffs and in deep rocky 
canyons. 
ADDITIONAL SPECIMENS EXAMINED: Organ Mountains, September 17, 1898, May 
15, 1892, Wooton; Van Pattens, August 29, 1894, July 27, 1902, Wooton. 
This plant near O. neomewxicanus, but has smaller leaves, flowers, and fruit, 
and nearly glabrous leaves, and the pubescence of the branches and petioles is
