— Fort Vancouver to Winnipeg valley and southward along the 
Rocky Mts. to N. Mexico and Arizona; flowering through the sum- 
mer; very variable, especially in pubescence. A lanate form has 
been found by Bourgeau in the Winnipeg valley ; a form distinguished 
by its broader thinnish leaves, purple glandular pubescence, and more 
distinctly ovate calyx, has been collected in the Uintas, Watson, and at 
Gray’s Peak, Hooker § Gray, Patterson. 
= = Capsule more or less distinctly stiped : petals conspicuously exserted. 
L. elata, Wats. Finely grayish-pubescent : stems erect, simple : 
leaves lanceolate or linear-oblong; the radical spatulate, 3-4 inches 
in length: flowers nodding on short spreading pedicels: calyx mem- 
branaceous, inflated, oblong, with rather short triangular teeth: petals 
purplish, exserted 4-5 lines from the calyx-tube; the blade bifid, each 
segment bearing a short narrow lateral tooth ; the claw distinctly and 
rather broadly auricled: stipe of the capsule over a line in length. —

ser. 2, xxxiii. 405.— Rocky Mts., British America, Bourgeau ; Colo- 
tado, Parry, Miss Eastwood, Letterman. This species much resembles 
Silene Hallii, except in the number of styles. Careful observations 
upon the constancy or variability of this character are greatly to be 
desired. 
L. Parryi, Wars. Viscid-glandular: stems several, nearly naked, 
Scarcely a foot in height: leaves linear, 1-2 inches in length: flowers 
erect or nodding on rather short pedicels: calyx oblong or obovate, 
inflated, purple-nerved: petals exserted 2-3 lines, the blade short, 
bifid, and with lateral teeth ; the claw as in the preceding; appen- 
dages broad and blunt ; stipe of the capsule about a line in length. — 
Proc. Am. Acad. xii. 248.— Northwestern Wyoming, Parry. Styles 
sometimes 4, 
L. nuda, Wars. Finely pubescent, slightly viscid: stems erect, 
slender, bearing but 2-3 rather remote pairs of short linear leaves : 
radical leaves oblanceolate, acute, attenuated below to long slender 
petioles : flowers few, the lower on branches 2-3 inches long: calyx — 
‘omewhat firmer than in the two preceding, not at all inflated, at first 
rather narrowly oblong, becoming obovate in fruit: petals white or 
rose-colored, 7-8 lines long; the blade bifid; the segments again 2-_ 
cleft; the claw broadly auricled, less attenuate to the base than in the —
