branches : calyx tubular, narrowed below, an inch long, with narrow subulate teeth (3 to 4 

 lines in length) : petals narrow, scarcely exserted from the calyx, cleft into 4 or more 

 filiform segments : seeds doubly crested with short vesicular hairs. — Proc. Am. Acad. xvii.

 San Jacinto Mts., H. M. Hall ; fl. August. 



++ -H- Flowers smaller, not ordinarily exceeding 6 or 8 lines in diameter. 



= Flowers borne in the forks of the branches and forming a leafy inflorescence : calyx 

 oblong or campanulate : leaves lanceolate to orbicular. 



S. campanulata, Watson. Finely glandular-pubescent : root thick, simple : rootstock 

 branching, somewhat woody : stems slender, erect, leafy : leaves sessile, lanceolate : flowers 

 on short deflexed peduncles : calyx green, broadly campanulate, reticulate-veined, toothed 

 nearly to the middle : petals narrow ; the limb cleft into 4 or more flesh-colored segments : 

 capsule globular, 3 to 4 lines in diameter. — Proc. Am. Acad. x. 341 ; Brew. & Wats. 1. c. 63. 

 — Mountainous districts of N. California and S. Oregon. 



Var. Greenei, Watson. More pubescent throughout: leaves ovate: petals greenish 

 white. — Wats, in Robinson, Proc. Am. Acad, xxviii. 137. — California, Yreka, Greene, 

 Trinity Co., Blankinship ; Oregon, Canonville and Wolf Creek, Howell Bros., Ashland, 

 Henderson. Apparently the commonest form. 



Var. orbiculata, Robinson, n. var. Tomentulose : leaves shorter, rotund in general 

 outline, half inch in diameter, with a very short acuminate tip, broadly cordate and amplexi- 

 caul at the base. — Elevated ledges above Hetten Chow, Trinity Co., Calif., Blankinship, 

 23 June, 1893. 



S. Menziesii, Hook. Finely glandular-pubescent : stems weak, leafy, dichotomously 

 branched above, 6 inches to a foot or more in height: leaves ovate-lanceolate, acuminate at 

 each end, thin : flowers very small for the genus : calyx obcouical, obovate, or oblong, only 

 2^ to 4 lines in length : petals white, 2-cleft, commonly but not always unappendaged : 

 capsule li to 2 lines in diameter. — Fl. Bor.-Am. i. 90, t. 30; Torr. & Gray, Fl. i. 193, G76;

 Kellogg, Proc. Calif. Acad. Sci. iii. 44, f. 12. — From S. Missouri, Blankinship, Nebraska, 

 Williams, to Assiniboia, and westward and sonthwestward to Vancouver Isl., S. California, 

 and New Mexico. 



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

 petals cleft into four or more narrowly linear almost filiform segments: styles loiig- 

 exserted : leaves small, lanceolate, chiefly clustered upon the more or less cespitose base. 



S. Lemmoni, Watson. Smoothish and green or more or less hoary-puberulent, finely 

 glandular and viscid above : root single ; rootstock considerably branched : stems slender, 6 

 to 14 inches high, bearing 3 to 6 loosely paniculate or subracemose flowers: leaves oblance- 

 olate to linear-oblong, acute : calyx in fruit obovoid, more or less narrowed below ; nerves 

 green, those of the short ovate-lanceolate teeth rather broad : petals with spatulate pubes- 

 cent claws ; blades divided into 4 linear-filiform segments ; appendages linear, entire : 

 seeds reddish or ashy. — Proc. Am. Acad. x. 342; Brew. & Wats. Bot. Calif, i. 64. S. 

 Palmeri, Wats. 1. c. xi. 124; Brew. & Wats. 1. c. 6.5, an indistinguishable form of S. Calif. 

 S. longistylis, Engelm. in Wats. 1. c. xxii. 469, merely a narrow-leaved and somewhat canes- 

 cent form of the north. — Mountainous regions from Ashland Butte, S. Oregon, througliout 

 California to Cuiamaca Mts., San Diego Co., Palmer ; fl. May to July. The three species 

 here united are now known from fairly copious intergrading material which leaves no 

 doubt that the supposed specific differences are of a trivial and inconstant nature. 



==== = Inflorescence as in the preceding : petals 2-cleft into linear segments : styles very 

 long, the exserted portion as long as the calyx. 



S. Bridgesii, Rohrb. Pubescent and viscid : stems leafy, usually simple up to the inflores- 

 cence, a foot or more in height : leaves sessile, lanceolate, acute, H to 2 inches long : flowers 

 slender-pedicelled, verticillately racemose or somewhat paniculate, nodding : calyx narrowly 

 oblong or clavate in anthesis, liroadly obovate in fruit ; the teeth acute ; the principal nerves 

 broad, green; the commissural much narrower, seldom anastomosing with the others: 

 petals half to three fourths inch long, considerably exserted, white or purplish : seeds very
