pauciflora, Porter in Hayden, Rep. 1870, 473. Silene Drummondii, 

 Hook. Fl. Bor.-Am. i. 89 ; Torr. & Gray, Fl. i. 191 in part ; Rohrb. 

 Monog. Sil. i. 83. Elisanthe Drummondii, Rupr. Fl. Cauc. i. 200. 

 — 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 fy Gray, Patterson. 



= = Capsuie 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-o 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. — 

 Proc. Am. Acad. xii. 249. Silene Scoideri, Gray, Am. Journ. Sci. 

 ser. 2, xxxiii. 405. — Rocky Mts., British America, Bourgeau; Colo- 

 rado, Parry, Miss Eastwood, Letterman. This species much resembles 

 Silene H(dlii, except in the number of styles. Careful observations 

 upon the constancy or variability of this character are greatly to be 

 desired. 



L. Parryi, Wats. 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. imda, Wats. 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 

 somewhat 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
