 330 {S. Engelmanni, Rohrb. Linnjea, xxxvi. 264), is a form of the same species, differing 

 from the type only in the somewhat broader lobes of the petals and in the obtuse appen- 

 dages. — California, Yosemite Valley, Bridges, Gratj ; Mt. Bullion, Bolander ; Danah, Cong- 

 don. A closely similar if not identical plant has been found by Rattan on the Klamath River. 



^ = z=z = Flowers scattered, or variously paniculate (in S. montana, var. rigidula, and 

 sometimes in S. repens, denser and subspicate or thyrsoid) : styles included or somewhat 

 exserted, but not so long as in the preceding. 



a. Fruiting calyx ovate, not contracted below, filled and distended by the subsessile 

 capsule. 



S. Thlirberi, Watson. Densely grayish-pubescent and glandular : stems erect, 2 feet high, 

 somewhat rigid, with ascending branches : leaves lanceolate, acute, contracted below, sessile, 

 2 to 4 ■ inches long : flowers small, ratlier numerous : calyx cylindric becoming narrowly 

 ovate, green and white striped, densely pubescent ; tlie teeth slender with fimbriate-laciniate 

 margin : petals white, little exceeding the calyx ; claws rather broad with upwardly pro- 

 duced auricles ; blades bifid with short oblong lobes, each with a small lateral tooth ; ap- 

 pendages oblong, obtuse : capsule narrowly ovoid, scarcely stiped ; seeds tuberculate and 

 distinctly crested. — Proc. Am. Acad. x. 343. S. pUcata, Wats. 1. c. xvii. 366. — Near 

 Janos, S. W. New Mexico, Thurber ; peak south of Rucker Valley, Arizona, Leminon. (Chi- 

 huahua, Pringle, Hartman ; Sonora, Hartman.) 



S. pectinata, Watson. Stems several, erect, 1-J to 2-J feet high : leaves lanceolate or 

 oblanceolate, acute or acuminate ; the lower long, tapering into winged petioles ; the upper 

 more or less reduced : flowers purplish rose-colored, 6 to 8 lines broad : calyx becoming 

 ovate in fruit : the teeth lance-linear to filiform, elongated, usually exceeding the mature 

 capsule : petals with narrow claws destitute of auricles ; blades obovate, bifid ; lobes 

 rounded; appendages lanceolate, entire : capsule large, ovate. — Proc. Am. Acad. x. 344 ; 

 Brew. & Wats. Bot. Calif, i. 65. — Plumas Co., Calif., Mrs. Ames, Sierra Co., Lenimon; 

 Carson City, Nev., Anderson. The typical form is very viscid-glandular and somewhat 

 branched. 



Var. SUbnuda, Robinson. Scarcely viscid : stems subsimple : radical leaves almost 

 smooth, the cauline much reduced. — Proc. Am. Acad, xxviii. 140. Lijchnis nuda, Wats. 

 Bot. King Exp. 37, & Proc. Am. Acad. xii. 248, is with scarcely a doubt merely a 5-carpelled 

 form from the Humboldt Mts., Watson. — Near Empire City and at Franktown, Nev., 

 Jones. 



b. Capsule distinctly stiped : calyx relatively narrow, cylindric or in fruit clavate or obovate 

 and usually rather distinctly contracted about the stipe of the capsule. 



1. Petals 4(-a)-fid. 



S. Oregana, Watson. Finely pubescent and very viscid, fetid : stems one or more, erect, 

 simple up to the racemiform or rather densely cymose-paniculate inflorescence : the lower 

 leaves oblanceolate, narrowed below to long petioles ; the upper leaves lanceolate or lance- 

 linear, sessile : petals white ; claws spatulate, glabrous, distinctly auricled at the summit ; 

 blades 2 to 3 lines long, variously cleft into 4 to 6 or more linear segments : stipe of the 

 ovoid capsule about 2 lines long. — Proc. Am. Acad. x. .343; Brew. & Wats. 1. c. — Moun- 

 tains of Oregon and Washington to Montana ; fl. April to August. 



S. montana, Watson, 1. c. Finely pubescent : stems erect from a more or less decumbent 

 base, 4 to 14 inches high: leaves lance-linear or narrowly oblanceolate, acuminate, 1 to 2^ 

 inches in length ; the cauline 3 to 4 pairs : inflorescence varying from subspicate to panicu- 

 late ; flowers rarely solitary : calyx 6 to 9 lines in length : petals greenish white to rose- 

 colored, exserted 2 to 4 lines : ovary long-stiped : cap.sule acutish. — Near Carson City, Nev., 

 Anderson ; Sierra Co., Calif., Lemmon. S. Shocldeyi, Wats. 1. c. xxv. 127, from the White 

 Mts., Mono Co., Calif., is apparently only a high-mountain form of the same species. 



Var. rigidula, Robinson, 1. c. Stems simple, a span high, slightly rigid : leaves short, 

 less than an inch in length, thickish and stiff : flowers white, subspicate. — Franktown, 

 Nev., Jones.
