SFH^ERALCEA. 



variously incised, or the uppermost linear and entire segments: raceme 

 short, spicate-crowded : petals deeply notched, half inch long: pedicels 

 very short : calyx thin, very hairy, its lobes ovate acute or acuminate: car- 

 pels small, smooth. Southwestern Oregon to California. 



S. campestris Greene 1. c. Bristly hairs of the stem abundant, forked 

 from the very base and deflexed : leaves soft beneath with stellate pubes- 

 cence which becomes dense on the pedicels and calyx : stems erect, 2-6 

 feet high simple or slightly branched above: lower leaves orbicular, about 

 9-lobed, the middle and upper 7-9-parted, their segments with 3-5 linear 

 spreading lobes : racemes short: petals emarginate, an inch long: calyx 

 lobes lanceolate acuminate, 3-nerved; carpels papillose-hirsute. In moist 

 places, Willamette valley. 



S. Oregana Gray PI. Fendl. 20. Slender, 1-3 feet high, merely puber- 

 ulent or glabrous up to the simple or paniculate racemes : foliage as in the 

 preceding, but the segments narrower; lobes of the calyx canescent. 

 broadly deltoid : petals 6-9 lines long: carpels obscurely rugulose-reticu- 

 lated. at least on the dorsal angles and sides, the back smoothish. Com- 

 mon in wet meadows and swales, British Columbia to California, east to 

 Idaho. 



S. Hendersoni Watson Proc. Am. Acad, xxiii, 262. ''Tall and appar- 

 ently perennial (3 or 4 feet high), glabrous throughout, the stem simple or 

 nearly so : leaves palmately 7-cleft to below the middle, the mostly broad 

 segments coarsely lobed and toothed, the upper leaves 3-5-parted and the 

 segments narrower: flowers large (9-12 lines long), in a loose raceme, the 

 pedicels (1-3 lines long), shorter than the linear bracts: calyx large {}4 

 inch long in fruit), the leaves ovate-lanceolate, shortly acuminate: carpels 

 few (8), smooth and glabrous, 2 lines long including the conspicuous lin- 

 ear beak. Near the shore of Clatsop Beach, Henderson," to Seattle, 

 Washington, Piper. 



3 sph^:ealcea st. mi. pi. Us. t. 51. 



Herbs or shrubs with angular or lobed leaves and mostly 

 showy flowers, solitary or fascicled in the axils of the leaves or 

 bracts, or in terminal racemes. Involucre 2-3-leaved, setaceous, 

 often deciduous. Calyx 5-parted, staminal column simple; free 

 filaments terminal and distinct, numerous. Styles 5 or more, 

 with capitate stigmas. Ovules 1-3, one ascending and maturing, 

 tlie others pendulous and abortive. Fruit conical. Carpels '2- 

 valved above, the upper portion where the seed is wanting thin- 

 walled and smooth, the lower half rugose-reticulated on the sides. 

 Seeds reniform. 



* Carpels 1-2, ovulate, the upper ovule when present abortive, at 

 length directly deciduous from the axis. Malvastrum Gray, in part. 



S. flfnnroana Spach. Hist. Veg. iii. 353. Malvastrum Munroanum 

 Gray. Grayish or hoary with dense stellate pubescence, branching from 

 the base. 1-2 feet long, usually spreading or ascending: leaves broadly 

 Ovate, usually cordate at base, more or less deeply 3-5-lobed, civnately 

 «ii- acutely toothed, L-2 inches long, equalling or exceeding the slender pet- 

 iole; calyx lobes a caite or acuminate, 2—4 lines long: p< tals'scarlet, broadly 

 obovate, 6-10 lines long: carpels oblong 2 lines long, pubescent on the 

 back. < >n gravelly banks along rivers, eastern Oregon and Washington to 



Nevada and Utah*. 



* * Carpels 2-3 ovulate, L-3 seeded: when separating from the 

 axis cohering by their sides and at base held by a kind of thread 

 which at length either tears away from the back of the carpel or else 

 is carried away with it. Tall perennial herbs.
