306 RANUNCULACE^. 



Nevadense, Wats. Bot. Calif, i. 11 (1876). Root with more numerous and 

 less fleshy tuberiform branches : stem low, stoutish ; herbage somewhat 

 fleshy, glabrous, glaucescent: leaves few, deeply cleft, the segments 

 cuneiform, deeply 3-lobed: raceme long and rather lax: fl. 1 in. broad, 

 deep blue, the long spur mostly strongly uncinate-incurved at tip : follicles 

 short, erect. — In the Sierra Nevada, near Truckee, Sonne, etc. May, June. 



12. D. decorum, F. & M. Ind. Sem. Petr. iii. 33 (1836). Root grumose, 

 the tuberiform branches ending in many coarse fibres: stem solitary, 

 slender, simple, mostly less than 1 ft. high: herbage of a very pale green, 

 pubescent or nearly glabrous : leaves small, parted into 3 — 5 rather widely 

 sundered segments, these broad-cuneiform, obtusely or acutely 3-lobed 

 in the radical ones, narrow and entire in the few cauline: fl. rather small, 

 in a somewhat open or more condensed raceme, deep blue, except the 

 white uppermost petals; spur straight: follicles glabrous, widely diver- 

 gent in maturity. — Common along the borders of thickets, or in more 

 open stony places, among the hills of the Coast Range, from perhaps 

 Santa Cruz, northward to Humboldt Co. Apr. 



13. D. pateus, Benth. PI. Hartw. 296 (1849): D. decorum, var. patens, 

 Gray, Bot. Gaz. xii. 54 (1887). Pale green and glabrous, or deeper green 

 and glandular-pubescent, very slender, 1 — 2 ft. high: leaves larger than 

 in the last, deeply 5-parted; segments narrowly cuneiform and deeply 

 incised: raceme very lax, the small flowers on almost filiform spreading 

 pedicels: spur longer than the sepals, abruijtly narrowed to the uncinate 

 tip: follicles glabrous or glandular-pilose, divergent. — At middle eleva- 

 tions of the Sierra, on the westward slope, where it is the analogue of 

 D. decorum, and evidently more than a mere variety of that species. 



* * Scarlet Jioivered species; the roots notflesliy. 



14. D. nudicanle, T. & G. Fl. i. 33 (1838): D. sarcophyllum, H. & A. 

 Bot. Beech. 317 (1840). Glabrous or slightly hairy; stem simple, 1—2 ft. 

 high, the leaves all near the base, long-petioled, 3 5-lobed, the segments 

 mucronately 3 — 7-toothed or lobed: raceme very lax, somewhat pju-ami- 

 dal, the lower pedicels greatly elongated: fl. 1 in. long or more; «epals 

 bright scarlet, not widely expanding, the spur straight; petalsV^Uow : 

 follicles glabrous, divergent at summit, sometimes narrowed at base to 

 a short stipe. Rocky slopes and summits of the Coast and Mt. Diablo 

 ranges of mountains, from Mendocino Co. to Mt. Hamilton and Santa 

 Cruz; also in the Sierra Nevada, according to Brewer & Watson. 



15. 1). cardinale, Hook. Bot. Mag. t. 4887 (1855): D. coccineum, Torr. 

 Pac. R. Rep. iv. 62 (1857). Stout, leafy up to the long rather dense raceme, 

 and of ten 5 —8 ft. high : leaves large; segments acuminate : fl. 1 in. broad; 

 sepals widely expanding: follicles (often 5 or 6) erect.— A magnificent 

 species, common in the Coast Range from perhaps near Monterey south- 

 ward throughout the State. July.
