1898] NORTH AMERICAN CARYOPHYLLACEA 167 
campanulate, externally pubescent; sepals four, ovate, 2 to 
y= long, narrowed to an obtusish apex, delicate in texture, 
herbaceous except on the margins, obscurely 3-nerved: petals 
none: stamens eight: styles three, recurved: ovary and cap- 
sule ovoid; seeds dark reddish brown, minutely roughened.— 
Collected in flower and fruit in alder woods of the upper valley 
of the Nesqually upon slopes of Mt. Rainier, Washington, June 
18, 1895, by Professor O. D. Allen and forming no. 157 of his 
valuable set of Cascade mountain plants; also collected but 
chiefly ina sterile state on clayey banks near Lake Cushman, 
August 1895, by Professor C. V. Piper. 
The affinities of the species are obviously with S. od¢usa Engelm., S. crispa 
Cham, & Schlecht., and \S. calycantha Bong. 5S. obtusa, however, is essentially 
Blaborus, and has thicker obtuser apparently glaucescent leaves and sepals, 
while S. crispa is wholly glabrous and has narrower attenuate sepals, which are 
hag distinctly ribbed near the base. S. ca/ycantha, on the other hand, 
east its lower flowers in the forks of a distinctly cymose inflorescence. 
aa ULIGINOSA Schleicher.— This species, long known, 
ough somewhat local, in alpine and boreal regions of 
ea : oti as in Siberia and Greenland, has been collected 
as. vga near Rama, northern Labrador, at about 300™

Slender aay tufted at the base and by its very long and
