840 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, 
linear-lanceolate, the longest 4 to 10 cm. long, 0.2 to 0.7 cm. wide, those at the base 
of the stem narrowed to petiole-like bases, those of the stem sessile, rounded to nar- 
rowed at base, partly clasping, all finely canescent-puberulent, the upper leaves 
and bracts more or less glandular-pubescent; thyrsus narrow, of 3 to 6 fascicles, each 
composed of 2 short axillary branches, their pedicels shorter than or equaling the 
peduncle; sepals 8 mm. long, lanceolate, acuminate, glandular-pubescent; corolla 
20 to 25 mm. long, the tube 4 to 5 mm. long, 3 to 3.5 mm. wide, the throat 8 to 10 mm. 
long, 8 to 9 mm. wide, much inflated and rounded, the lobes 8 to 10 mm. long, 8 mm. 
wide, the 2 posterior ones united and arched for one-half their length, the 3 anterior 
ones united slightly at base, all the free portions widely spreading, the corolla exter- 
nally glandular-puberulent, within somewhat pubescent over the bases of the ante- 
rior lobes, purplish blue, not or faintly lined within the throat; anther sacs widely 
divaricate, 1.4 to 1.5 mm. long, lance-oblong, with short line of contact, pale, or 
vaneee- need on side, from distal apex opening nearly throughout, the suture fimbrio- 
e filament 15 to 17 mm. long, more or less exserted, flattened, gradually 
enlarged distally, at times decurved at apex, densely bearded on the posterior face 
nearly to the base with orange-golden hairs; capsule 8 to 10 mm. long, ovate, acumi- 
nate, glabrous; seeds 2.5 to 3 mm. long, irregularly lanceolate-curved in outline, 
the angles obscure, the surface finely alveolate-reticulate, blackish brown. 
Type in the herbarium of the New York Botanical Garden, collected on a dry 
sandy sagebrush slope, east of Fountain Creek, northeast of Pueblo, Pueblo County, 
Colorado, altitude about 1,400 meters, in flower, June 5, 1915, by F. W. Pennell (no. 
5731). 
This species has been identified as P. jamesii Benth., but examination of the type 
of that species, in Torrey’s herbarium (Columbia Uniiventty Herbarium) at the New 
York Botanical Garden, shows that his name should replace P. similis A. Nels. 
P. similis occurs on the Staked Plains of eastern New Mexico and northwestern 
Texas, and it was doubtless on these or in near-by western Oklahoma, while on the 
return route of Long’s expedition, that Doctor James collected his plant. P. jamestt 
differs from P. auriberbis by having wider leaves, larger flowers, and anther sacs 
which dehisce throughout aia have a broad line of contact. 
Sandy or loam sagebrush slopes, at altitudes of 1,250 to 2,100 (2,200) meters; Upper 
Sonoran Zone; flowering mid-May to late June. High p lains in the Arkansas Valley 
of southeastern Colorado.
