 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. 



+- n- +- +- +- Leaves variously cleft or divided : achenes compressed, 

 usually 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.

 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 tongas 

 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

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 as long as the reflexed sepals: achenes broad and rounded, compress- 

 ed and thin, glabrous, tipped with a short recurved beak. In dry ground,

R. Rattani. R. occidentalis var. Rattani Gray Proc. Am. Acad, xxi, 372. 

 More or less villous w ith 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. PI. No. 1331. not Benth. Stems slender, smooth, 1-2 feet 

 hgih, widely branched 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-several from a fascicle of fleshy-fibrous perennial 

 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 lanceolate 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
