height ; leaves ovate-lanceolate, acuminate at each end, thin : flowers 

 very small: calyx obconical, obovate, or oblong, only 2^-4 lines in 

 length : petals white, 2-cleft, commonly but not always uuappendaged : 

 capsule 1^-2 lines in diameter. — Fl. Bor.-Am. i. 90, t. 30; Torr.

= = Flowers few, rather small, white or nearly so, nodding, borne in a lax 

 naked panicle : petals cleft into four or more narrowly linear, almost fili- 

 form segments : styles long-exserted : leaves small, lanceolate, chiefly 

 clustered upon the more or less cespitose base. 



S. longistylis, Engelm. Hoary-pubescent, minutely glandular 

 above: root single : rootstock branched: stems 2-several, slender, 6-12 

 inches high, bearing 3-6 loosely paniculate or subracemose heads : 

 leaves linear-lanceolate or oblanceolate, acute : calyx soon becoming 

 ovoid : petals with a spatulate very pubescent, scarcely or not at all 

 auriculate claw ; the blade divided into 4 linear filiform segments ; ap- 

 pendages linear, entire : capsule subsessile : seeds (apparently mature) 

 small, dark red. — Engelm. in herb. Wats. Proc. Am. Acad. xxii.

 "W. Oregon, Henderson ; specimens collected in Plumas Co., Cal. 

 {Mrs. Austin), and Mariposa Co. {Congdon), probably belong here 

 also. 



S. Lemmoni, Wats. Similar in habit: leaves broader, lanceolate, 

 quite smooth or somewhat pubescent and glandular : calyx inclined to 

 be herbaceous, especially the lanceolate acutish teeth, but the veins 

 from the different nerves seldom anastomosing with each other : petals 

 with a ratlier broad villous auriculate claw ; the four divisions of the 

 blade linear but not filiform : capsule nearly sessile : seeds red, some- 

 what irregular in shape, 1 line in length. — Proc. Am. Acad. x. 342 ; 

 Brew. & Wats. 1. c. i. 64. — California, Sierra Co., Lemmon ; Janesville, 

 Urandegee ; Mariposa Co., Gongdon; Coast Mts. north of San Fran- 

 cisco, Rattan. This species is too near the preceding and following, 

 and it is not unlikely that more abundant material may show inter- 

 gradation between them. 



S. Palmeri, Wats. Similar in habit, more or less pubescent 

 throughout, finely glandular above : leaves oblanceolate : calyx teeth 

 commonly short and blunt, scarcely herbaceous ; the base of the calyx 

 often contracted about the short but distinct stipe of the ovary : the 

 petals purplish ; the claw villous, narrowly or broadly spatulate but
