or triangular-ovate, obtuse, 3-nerved, about a line long, at length re- 
flexed; petals obovate, obtuse or notched at the apex, nearly 2 lines long. 
strongly 3-nerved, the lateral nerves arising below the middle and con- 
verging toward the apex; filaments subulate, shorter than the petals; 
carpels flat, surrounded by a disk, becoming globose-ovoid, nearly dis- 
tinct follicles 2-3 lines long, the short beaks strongly diverging: seeds 
obovoid. more or less pointed at both ends. On wet cliffs along the 
Columbia and Willamette rivers. 
S. claytoniefolia Canby, Small 1. c. 365. Perennial by a short hori- 
zontal rootstock, slender, glandular-pilose above, glabrate below: leaves 
fleshy, orbicular-elliptic, more or less oblique, 3-4 inches long, glabrate, 
obtuse, entire, undulate, palmately 6-8-nerved, narrowed into a winged 
ribbed petiole which is as long as the blade or longer: stems erect or 
assergent 8-12 inches high, glabrate near the base; inflorescenve thyr- 
soid-corymbose, its branches subtended by small linear or linear-oblong 
bracts: calyx flattish, 1 line high, its lobes spreading and recurved, thin, 
oblong, acute, 3-nerved, longer than the tube; petals white, spatulate or 
oboyate-spatulate, about 1 line long, slightly emarginate or minutely 
apiculate, gradually narrowed into a claw, marked with a stout mid-nerve 
which gives off two lateral nerves about the middle; filaments subulate, 
shorter than the petals, incurved at the summit; carpels each ovoid, 1% 
lines long, the short stout beaks strongly diverging; seeds irregularly ob- 
long, reddish, smooth or very faintly striate. Damp crevices of rocks, 
The Dalles, Oregon. 
S. nidifica Greene Eryth. i, 222. ‘‘Near S. integrifolia, but crown and 
roots imbedded in a dense subglobose mass of small bulblets: leaves 
ovate or obovate, entire or merely denticulate, an inch long, on dilated 
petioles rather shorter: scapes 8-12 inches high, stoutish, glandular-hir- 
sute: cymes several-flowered and pedicillate, forming a thrysoid panicle 
toward the summit: calyx-segments ascending, oblong-ovoid, acutish and 
mucronulate : ine round-obovate, not unguiculate, whlte: filaments 
very short; anthers dull red: ovary very broad at summit, depressed and 
even slightly concave: carpels not known.’”’ In wet springy places, east- 
ern Washington to the Sierra Nevada Mountains in California. 
S. plantaginea Smaijll.c. ‘Perennial by a thick rootstock, stout, 
scapose, glandular-pilose: leaves eiliptic or elliptic-spatulate, 2-4 inches 
long, obtuse, undulate or distinctly and shallowly toothed, leathery, cili- 
ate, 5-7-ribbed, narrowed into a winged petiole, which is usually much 
shorter than the blade; scape erect, 8-10 inches tall, sparingly branched 
near the top, the branches subtended by elliptic bracts; flowers greenish; 
in dense cymules; calyx flat, its segments ovate, 2 lines long, obtuse, 3- 
nerved, longer than the tube; petals suborbicular-oblong or some i.- 
clined to be broadly spatulate, 1-2 lines long, greenish, shorter than the 
calyx-segments, obtuse, marked with a midnerve and several branches 
narrowed into a broad claw; filaments converging, subulate, shorter than 
siya: ovaries immersed in a lobed disk, fruit not seen.’”’? Spokane, Wash- 
ington. 
S. intergrifolia Hook FI. i, 249, t. 86. Glandular-puhescent through- 
out; leaves and stems from a somewhat woody caudex: leaves ovate to 
oblong or lanceolate, usually obtuse, entire or slightly sinuate-crenate, 
somewhat membranaceous; stems 6-20 inches high, rather stout: flowers 
many, in an elongated panicle, on short pedicels, clustered at the ends of 
the branchlets of the narrow panicle; petals white, obovate, twice the 
length of the glabrous spreading sepals; filaments short, subulate; ovary 
free: styles divergent: carpels united only atthe base. In moist prairies 
and wet places, Washington to California.
