like bases about one-half their length, those of the stem similar, narrowly lanceolate, 
clasping, the largest 6 to 10 cm. long, 0.7 to 0.9 em. wide; thyrsus narrowly racemi- 
form, strongly secund, less than one-half the height of the plant, composed of 7 to 10 
fascicles, each consisting of 2 erect axillary branches; longer pedicels exceeding the 
peduncle; sepals 4 to 6 mm. long, ovate, with an acuminate tip about one-half the 
length of the body, obscurely veined in fruit, with conspicuous broad, white, scarious, 
coarsely and irregularly denticulate margin, finely and sparsely glandular-puberulent; 
corolla about 20 mm. long, the tube and throat 15 mm. long, the tube narrow, the 
throat inflated and rounded ventrally, the 2 posterior lobes 5 mm. long, united and 
arched one-half their length, apparently spreading, the 3 anterior lobes slightly 
longer, united at base, the free portions spreading; corolla glabrous without and 
within, probably blue (not seen fresh); anther sacs widely divaricate, 1.2 to 1.4 mm, 
long, oblong-lanceolate, distinct, opening from the distal apex nearly throughout, 
pubescent on the side with loose white hairs, their length not exceeding the width 
of the sacs; sterile filament shorter than the anterior ones, gradually enlarging dis- 
tally, flattened, bearded on the posterior face distally with scattered (or at apex 
dense) short yellow hairs; capsule 8 to 9 mm. long, ovate, acuminate, glabrous, 
brownish; seeds about 2 mm. long, irregularly quadrangular in outline, curved, 
the angles sharp, not winged, the surface finely alveolate-reticulate, brown, slightly 
glistening.
