S.* parviflora, Greene. Stems several, quite glabrous toward the base, subsimple, termi- 

 nating in long slender loose racemes : lowest leaves orbicular, crenate-toothed, the others 

 deeply divided, with divisions lobed : flowers small; pedicels (2 to 3 lines long) subtended 

 by simple linear bractlets scarcely their ow^n leugtli : calyx somewhat hirsute-pubescent : 

 petals a third to lialf iuch long : carpels glabrous, at length distinctly reticulated ; beak 

 somewhat recurved. — Erythea, i. 148. 5. malvcejiora, Torr. Bot. Mex. Bound. 38, in part,

 Parish, 3Iiss Cummings. (Sonora, at Ojo de Gavilan, where first coll. by Thurher in 1851.) 

 Chiefly distinguished from the preceding by the smooth stem and considerably smaller 

 flowers borne in longer more slender racemes. Prof. Greene (1. c.) states that Mr. Parish's 

 specimen (no. 2080) was referred by Dr. Gray to «§. glaucescens. It was collected, however, 

 in May, 1889, more than a year after Dr. Gray's death. 



Var.* (^) Thurberi, Robinson, n. var. A foot high: leaves small, chiefly basal; 

 those of the almost naked stems sparse, divided into narrow linear segments : flowers white. 

 — Las Playas, Sonora, near the U. S. boundary, Thurber, 334, 340, and perhaps also in New 

 Mexico or Arizona. 



S. asprella, Greene. No hirsute or hispid pubescence whatever : stem 2 to 5 feet high, 

 simple, roughish with minute and dense stellular almost scurfy pubescence, or below gla- 

 brous : leaves moderately lobed or only uppermost dissected, pubescent with few-rayed short 

 stellular hairs : raceme virgate, loosely flowered, very naked : pedicels sometimes longer 

 than fruiting calyx, commonly very short : petals usually inch long : calyx canescent, in 

 fruit mostly 5 lines long ; lobes from ovate becoming triangular-lanceolate : carpels rugose- 

 reticulated throughout and glabrous at maturity, becoming concave or grooved on the back 

 and acute-angled at sides. — Bull. Calif. Acad. Sci. i. 78, founded on a lax and decumbent 

 leafy state, perhaps from growing in thickets ; Gray, Proc. Am. Acad. xxii. 286. — Hillsides 

 of the lower Sierra Nevada, from Yuba to Siskiyou Co., Greene, Mrs. Curran ; at Chico de- 

 scending to the low foot-hills, where the stem is strict. 



S. campestris, Greene. Either glabrous up to the inflorescence or with some hirsute 

 pubescence at least below and close stellular cinereous pubescence above : stems 2 to 5 feet 

 high, when large branching above : rounded lower leaves variously lobed ; u])per usuall}' 

 5-7-parted into narrow divisions : racemes strict, either rather dense and spiciform or 

 more loosely flowered: petals over half 1)ut rarely full inch long, tlieir emarginate summit 

 often laciniate-erose : calyx 4 or 5 lines long at least in fruit, minutely canescent, some- 

 times also with soft slender hairs, sometimes nearly glabrous ; the lobes in age usually lan- 

 ceolate-acuminate : carpels roughish rugose- or favose-reticulated and commonly pubescent, 

 the back rather rounded and dorsal angles olttuse. — Bull. Calif. Acad. Sci. i. 76 (founded 

 on one form) ; Gray, 1. c. S. Oreijana, Gray, PI. Fendl. 20, partly. i Sida malva-Jlora, Lindl. 

 Bot. Reg. t. 1036; Hook. Fl. Bor.-Am. i. 108. — Moist meadows, where usually smooth or 

 glabrate, or dry hills or jdains, there more pubescent and base of stem with radical petioles 

 hirsute with deflexed or spreading hairs, N. California to Brit. Columbia west of the Cascade 

 Range ; first coll. by Douglas. 



S. Oregana, Gray. Very like the last preceding, merely puberulent or nearly glabrous 

 uj) to the inflorescence, 2 to 5 feet high : racemes simjjle or commonly paniculate, at length 

 loosely flowered : flowers comparatively small : petals a third to half inch long : calyx 

 canescent, in fruit 2 or 3 lines long and the lobes broadlj' deltoid : carpels obscurely rugulose- 

 reticulate<l, at least the dorsal angles and sides, the back smooth or smoothish. — PI. Fendl.
