WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 171 
° SCROPHULARIACEAE. 
Castilleja eremophila Wooton & Standley, sp. nov. 
Perennial from a slender root, the stout, solitary stems 10 to 15 cm. high, 
cinereous-puberulent; a few of the lowest leaves linear-oblanceolate, the others 
pinnatifid, each with 1 or 2 pairs of oblong-linear, divergent or ascending, 
obtuse lobes, all dull green, thin, cinereous-puberulent, sessile, not conspicuously 
veined ; flowers rather few, crowded; bracts narrow, acute, usually with several 
linear lateral lobes, glandular-puberulent or slightly villous; calyx 16 to 20 mm. 
long, about equally cleft before and behind, the lateral divisions each cleft at 
the summit into 2 oblong-lanceolate, acute segments, glandular and villous, 
scarlet at the tips; corolla about 25 mm. long, the short tube about 10 mm. 
and the galea 15 mm. long, the tube glabrous, greenish, the galea puberulent, 
yellowish green faced with scarlet, the lower lip of 2 glabrous, green, oblong- 
lanceolate, acute teeth about 1 mm. long. 
Type in the U. S. National Herbarium, no. 687232, collected on arid, sandy 
mesas about the north end of the Carrizo Mountains, July 31, 1911, by Paul C. 
Standley (no. 7464). Additional material is mounted on sheet 686431. 
The plant is somewhat like C. chromosa A. Nels., but is much lower and 
has always solitary stems; the pubescence is very different besides. It grows 
in the most arid situations in the Upper Sonoran Zone. No other Castilleja 
was found growing at so low an altitude, C. integra having a habitat most 
nearly approaching that of this species. 
Dasystoma wrightii (A. Gray) Wooton & Standley. 
Gerardia wrightit A. Gray, U. S. & Mex. Bound. Bot. 118. 1859. 
Mimulus parvulus Wooton & Standley, sp. nov. 
Slender annual with almost filiform, prostrate or ascending branches not 
more than 4 or 5 cm. long, often rooting at the nodes; stems mostly glabrous; 
leaves thin, 4 to 8 mm. long and fully as wide or wider, broadly rounded-ovate, 
obtuse, subcordate at the base, short-villous with white hairs, entire or ob- 
scurely denticulate, on slender petioles half as long as the blades or longer; 
pedicels axillary, very slender, exceeding the leaves, glabrous or sparingly 
villous; calyx turbinate or narrowly campanulate, sharply angled, 5 mm. long 
in fruit, in flower not much shorter, purplish, oblique at the mouth, sparingly 
villous with coarse, white hairs; corolla bright yellow, 8 or 9 mm. long, the 
slender tube more than twice as long as the calyx; capsules 2 mm. long, nar- 
rowly oblong, abruptly acute. 
Type in the U. 8. National Herbarium, no. 660448, collected in Rocky Canyon, 
Grant County, August 9, 1911, by J. M. Holzinger. 
A most distinct species, very unlike any of our other southwestern ones and 
apparently very different from any of those from farther west or south. 
Pentstemon cardinalis Wooton & Standley, sp. nov. 
Perennial, forming dense clumps 40 cm. in diameter or more; stems rather 
slender, erect, simple, glabrous, green; basal leaves elliptic-spatulate, obtuse, 
long-petiolate ; cauline leaves various, the lower oblong-lanceolate, obtuse, 13 cm. 
long or less, narrowed at the base, the upper ones oblong to triangular-ovate, 
acutish or acuminate, sessile by a truncate or clasping base, thin, glabrous; 
bracts triangular-subulate, very small; inflorescence thyrsiform, secund, loosely 
many-flowered, glabrous; pedicels slender, erect, conspicuous; sepals 4 mm. 
long, lance-ovate, acute, scarious-margined; corolla 22 to 28 mm. long, eardinal 
red, considerably dilated in the throat, contracted at the mouth, the upper
