_R. eremogenes Greene Eryth. iv, 121. R. sceleratus of authors as to 
the western plant. Glabrous: stem erect, stout and fistulous, 6-30 inches 
high, sparingly leafy, simple below, loosely corymbose-paniculate above, 
herbage light-green; lower leaves round-reniform, deeply 2-5-lobed, the 
lobes obtusely-toothed above ; upper leaves more deeply and narrowly cut: 
petals light yellow, surpassing the sepals: achenes numerous, smooth, flat- 
tened, with very short beak, crowded in a short-oblong head: the oblong- 
ovoid receptacle much inflated. Wet springy places, northern California 
to Brit. Columbia and the Rocky Mountains; east of the Cascade Mts. 
+ + + + + Leaves variously cleft or divided: achenes compressed, 
ay flat, surrounded by a firm or indurated margin: none truly 
alpine. 
++ Radical leaves not divided into separate leaflets: petals usually 
only 5: achenes smooth or barely pubescent, in globose or oblong heads. 
= Style long, recurving, wholly persistent in a rigid and uncinate, 
elongated beak. 
1 Perennials with erect stems from somewhat fleshy-fibrous roots. 
R. occidentalis Nutt. T. & G. Fl. i, 22. Pilose with spreading hairs: 
stems rather slender, 10-18 inches high, at length much branched: radical 
leaves orbicular, subcordate, more or less deeply 3-lobed, or 3-parted, and 
coarsely toothed, an inch or less in diameter; cauline leaves deeply cut 
into 3-5 linear lobes: petals obovate-oblong, 3-7 lines long, twice as long as 
the reflexed sepals: achenes smooth or nearly so, flat, a line in diameter; 
beak nearly as long as the body; heads globose. Common in dry open 
places, Oregon to Alaska and the Rocky Mountains, 
R. Eiseni Kellogg Proc. Cal. Acad. vii, 115. Sparingly villous: stems 
slender, at length widely branched above, 1-2 feet high: leaves rather 
small, not cordate at base, palmately 3-lobed or 3-parted, the broad cunei- 
form lobes of the radical ones trifid: petals obovate-oblong, 3-5 lines long, 
twice aslong as the reflexed sepals: achenes broad and rounded, compress- 
ed and thin, glabrous, tipped with a short recurved beak. In dry ground, 
mountains of southern Oregon to middle California.

More or less villous with long white hairs: stem slender, 1-2 feet high, 
-widely branching above: leaves palmately 3-parted or 3-lobed, not cordate 
at base, the broad cuneiform lobes of the radical ones trifid: sepals 2-3 
lines long, reflexed; petals obovate-oblong, 4-6 lines long or more: achenes 
becoming roughish-papillose, and sparsely or thickly beset with short 
hairs. Dry ground, southern Oregon and northern California.

R. canus Howell P. C. Pl. No. 1331. not Benth. Stems slender, smooth, 1-2 feet 
hgih, widely tranched above: leaves broadly cuneate, palmately 3-5-lobed 
or -parted, the cuneiform segments 3-toothed or -lobed, canescent with a 
long appressed-silky pubescence: sepals ovate, acute, pubescent outside, 
soon reflexed, 2-3 lines long: petals obovate-oblong, 4-6 lines long or more: 
achenes rather small, smooth, tipped with a subulate, slightly hooked to 
almost straight, elongated style. Dry hillsides about Ashland Oregon, 
extending to near the Klamath river in California. 
R. ciliosus. ‘Soft-pubescent with moderately long, white, at length 
spreading hairs: stems 1-seyeral from a fascicle of fleshy-fibrous perenniai 
roots, erect or ascending; lower leaves 3-parted, the obovate or oblanceo- 
late segments acutely 2-5-lobed ; the cauline 3-parted, the acute lanceolate 
segments entire or 2-3-lobed; the uppermost ianceolate and entire: sepals 
ovate, acutish, 2-3 lines long, soon reflexed; petals broadly obovate, 4-6 
lines long: young achenes roundish, ciliate on the outer edge. tipped with
