25. Benstemon laevis Pennell, sp. nov. 
Stems one or several 40 to 70 cm. tall, from a short branched caudex, glabrous 
throughout, glaucous; leaves pale dull green, somewhat glaucous, obscurely veined, 
glabrous, those at the base of the stem with narrowly obovate to ovate, obtuse (at 
times retuse, with or without a mucro) blades, altogether 10 to 15 cm. long, 2 to 3. cm. 
wide, narrowed into petiole-like bases one-third the total length, the stem leaves 
similar, smaller, clasping from a more or less broadly rounded base (bases of opposite 
leaves nearly or quite meeting around stem), becoming reduced and bractlike 
through the inflorescence; thyrsus narrow, secund, about one-half the height of 
the plant, composed of 9 to 18 fascicles, each consisting of 2 short axillary branches, 
their pedicels probably exceeding the peduncle; sepals 4 to 7 mm. long, broadly 
ovate, more or less abruptly acuminate, not veined, with relatively broad erose- 
denticulate scarious margin, glabrous; corolla 20 to 30 mm. long, the tube and throat 
14 to 20 mm. long, the throat decidedly inflated and rounded ventrally, the 2 pos- 
terior lobes 6 to 10 mm. long, united and arched one-half their length, projecting, 
the 3 anterior lobes nearly equaling the posterior ones, united at base, the free por- 
tions spreading; corolla glabrous without and within, blue (not seen fresh); anther sacs 
widely divaricate, 1.8 to 2 mm. long, oblong-lanceolate, distinct, opening distally 
three-fourths their length, minutely puberulent; sterile filament shorter than the 
anterior pair, scarcely enlarging distally, flattened, bearded with yellow hairs on the 
posterior face near the apex; capsule not seen.
