height : leaves ovate-lanceolate, acuminate at each end, thin: flowers 
very small: calyx obconical, obovate, or oblong, only 24—4 lines in 
length : petals white, 2-cleft, commonly but not always unappendaged : 
capsule 14-2 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, Enezim. 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. ats. Proc. Am. Acad. xxii. 
469.— Scott’s Mts., N. California, Engelmann; Ashland Butte, S. 
W. Oregon, Henderson ; specimens collected in Plumas Co., Cal. 
(Mrs. Austin), and Mariposa Co. (Congdon), probably belong here 
also. 
S. Lemmoni, Wars. Similar in habit: leaves broader, Lente 
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 rather 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. l.c. i. 64. — California, Sierra Co., Lemmon ; Janesville, 
Brandegee ; Mariposa Co., Congdon; 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. 
- Palmeri, Wars. Similar in habit, more or less pubescent 
thréughout, 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 : = 
petals purplish ; the claw villous, narrowly or broadly spatulate bu
