172 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, 
lobes erect, the lower deflexed, nearly orbicular, 2 or 2.5 mm. long, strongly 
bearded in the throat with yellow hairs; anthers echinate along the commissure. 
Type in the U. 8. National Herbarium, no. 563916, collected on White Moun- 
tain Peak just above the forks of Ruidoso Creek, J uly 6, 1895, by E. O. Wooton. 
Altitude about 2,400 meters. 
This is somewhat, but not very closely, related to the group of P. puniceus 
and P. wrightii. The plants are not at all glaucous, however, and the form of 
the corolla is altogether different, especially in the contracted mouth. 
Pentstemon crassulus Wooton & Standley, sp. nov. 
Perennial from slender, fleshy roots and a stout caudex; stems stout, 45 em. 
high or less, simple, erect, glabrous, purplish above; basal leaves narrowly 
oblanceolate, short-petiolate, acute or obtuse, 10 em. long or less; cauline leaves 
all sessile, narrowly oblong to triangular-lanceolate, acute or abruptly acumi- 
nate, glabrous, thick and rather fleshy; inflorescence secund, loosely few- 
flowered, glabrous; pedicels slender, erect; sepals 6 mm. long, broadly ovate, 
obtuse or abruptly short-acuminate, scarious-margined; corolla about 25 mm. 
long, red, much dilated in the throat and sparingly bearded, contracted at the 
mouth, the upper lobes erect, the lower deflexed, nearly orbicular, short, about 
2 mm. long. 
Type in the U. 8. National Herbarium, no. 563082, collected in the Lincoln 
National Forest in 1903 by Fred G. Plummer. 
Similar in general appearance to P, cardinalis, but the calyx lobes are shorter 
and broader and obtuse, and the leaves thick and fleshy and of different outline. 
Pentstemon neomexicanus Wooton & Standley, sp. nov. 
Perennial from a slender, creeping rootstock; stems stout, erect, simple, 
50 to 70 em. high, glabrous; basal leaves linear-oblanceolate, acute, petiolate, 
8 cm. long or less; cauline leaves oblong to linear, acutish or obtuse, 6 to 10 
em. long, thick and fleshy, glabrous, rather numerous, scarcely reduced above: 
leaves of the inflorescence reduced, the lowest sometimes longer than the 
flowers ;-inflorescence much elongated, thyrsiform, secund, many-flowered, gla- 
brous; pedicels stout, short; calyx lobes obovate to oblong, 4 to 5 mm. long, 
truncate or obtuse, abruptly short-mucronate, erose-denticulate at the apex, 
Scarious-margined ; corolla 22 to 25 mm. long, deep bright blue, with a dilated 
throat and spreading limb, the lobes rounded, strongly hairy in the throat; 
capsules ovoid-conic, 5 or 6 mm. high. 
Type in the U. S. National Herbarium, no. 561371, collected in pine woods 
near Gilmores Ranch on Eagle Creek in the White Mountains, altitude 2,220 
meters, August 15, 1907, by E. O. Wooton and Paul C. Standley (no, 3507).

A very common and handsome plant in the higher parts of the Sacramento, 
White, and Capitan Mountains. It is most nearly related to P. unilateralis 
Rydb., but has very different calyx lobes and a hairy instead of glabrous throat. 
That species is found in New Mexico only in the higher mountains near the 
Colorado border. 
Pentstemon oliganthus Wooton & Standley, sp. nov.

xbove; basal leaves oblong or oval, petiolate, obtuse, 2 cm. long or less; cauline
