35. Penstemon scariosus Pennell, sp. nov. 
Stems several, 20 to 30 cm. tall, from a branched caudex, sparsely glandular- 
puberulent in the inflorescence, dull or slightly glaucous; leaves apparently dull 
green and somewhat glaucous, obscurely veined, glabrous, those at the base of the 
stem with broadly oblanceolate, acute blades 6 to 7 cm. long, narrowed into petiole- 
like bases about two-thirds the length of the blade, those of the stem similar, lanceo- 
late, clasping (bases of the upper meeting around stem), the largest 7 to 9 cm. long, 
0.9 to 1.1 cm, wide; thyrsus narrow, racemiform, strongly secund, about one-third 
the height of the plant, composed of 4 to 6 fascicles, each consisting of 2 axillary 
ascending branches; pedicels shorter than or equaling the peduncle; sepals 8 to 12 
mm, long, ovate-lanceolate, with a caudate tip nearly or quite equaling the length 
of the body, obscurely or not veined, proximally with a conspicuous broad, white, 
scarious, slightly denticulate margin, sparsely and minutely glandular-puberulent; 
corolla about 30 mm. long, the tube and throat 20 mm. long, the tube narrow, the 
throat inflated and rounded ventrally, the 2 posterior lobes 10 mm. long, united and 
arched two-fifths to one-half their length, the free portions projecting, the 3 anterior 
lobes slightly longer, united at base, the free portions spreading; corolla externally 
glabrous, within glabrous or slightly pubescent over bases of anterior lobes, blue 
(not seen fresh); anther sacs widely divaricate, 1.8 mm. long, oblong-lanceolate, 
distinct, opening from the distal apex for three-fourths to four-fifths their length, 
densely pubescent on the side with loose white hairs, their length not exceeding the 
width of the sacs; sterile filament shorter than the anterior pair, gradually enlarging 
distally, flattened, bearded on the posterior face distally with scattered (or at apex 
more dense) short yellow hairs; capsule not seen.

Tescence), from a stout branched caudex, dull or slightly glaucous; leaves appar- 
ently dull green and somewhat glaucous, obscurely veined, glabrous, those ate the 
base of the stem with lanceolate acute blades 6 te 7 cm. long, narrowed into petiole-
