ing somewhat cuneately from the middle to the acute ends, 3-4 
cm. long, entire or with a few irregular acute teeth, the veins con- 
spicuous and the margin slightly thickened-revolute; petioles 
slender, 4-6 mm. long, dilated and somewhat connate at base: 
flowers in the upper axils, mostly twin, drooping, on short pedi- 
cels: calyx minute, less than 2 mm. long, acetabuliform, its lobes 
about as long as the shallow cup: ovary oblong, 3-4 mm. long, 
about twice as long as the lanceolate bracts at its base, which in 
turn are about as long as the pedicels —all of these structures 
purplish-blue as if with bloom: corolla ochroleucous tinged with 
pink, gradually dilated-tubular, less than 1 cm. long, its rounded 
lobes half as long as the tube, nearly glabrous within, only a few 
inconspicuous hairs near the middle of the tube, glandular from 
the hairs down: filaments shorter than the anthers; style glab- 
rous, half as long as the corolla; fruit not known. 
This is a member of the S. oreophilus group, which now con- 
tains several species. Among them, however, there is’no species 
so wholly glabrous, nor with leaves like those of the species now 
proposed. The floral characters, while characteristic, are less 
noticeable, 
The type is xo. 1025, by Merrill and Wilcox, Teton Moun- 
tains, Wyoming, July 26, 1901. Paratypes (probably) in the 
National and in the New York Botanical Garden herbaria.
