7. D. troUi folium, Gray, Proc. Am. Acad. viii. 275 (1872). Glabrous 

 or somewhat pubescent; 2 ft. high or more: lower leaves very large, 

 long-petioled, 5 -7-lobed; lobes cuneate, usually closely approximate, 

 the sinus closed, the summit laciniately cleft and toothed: raceme loose, 

 the pedicels, especially the lower, elongated and ascending: fl. middle- 

 sized, bright blue (but petals white); the stout spur as long as the sepals 

 or longer, gently curved downwards throughout its length: follicles 

 glabrous, recurved-spreading. — In shady places from Humboldt Co. south- 

 ward to Monterey, m the Coast Bange only, and not seen in the Bay 

 region. The Monterey plant (McLean, 1874) is not quite like the type, 

 and may be distinct.

 tuberiform or grninoiis.

 azure Km, Torr. Bot. Wilkes Exp. partly, not Michx. Root fleshy and

 high, very leafy up to the narrow and dense virgate raceme: leaves light 

 green, glabrous, thickish, the lowest cleft to the middle, or more deeply, 

 into oblong callous-tipped lobes; divisions of the upper successively 

 deeper and narrower, those of the uppermost narrowly linear: fl. smallish,

 straight, horizontal, twice the length of the sepals : follicles short, thickish, 

 erect. — Plains of Humboldt Co. or Mendocino, Kellogg, northward to the 

 British boundary, in rather moist open ground. July, Aug. 



9. D. nligiiiosnm, Curran, Bull. Calif. Acad. i. 151 (1885). Roots 

 scarcely fleshy, rather woody-fibrous but thick : stem leafy at base only, 

 1 ft. high or more ; herbage deep green, almost glabrous : leaves fiabelli- 

 form, 3-cleft, the segments about 3-toothed: fl. few, rather large, deep 

 blue, in an open raceme; spur slender, straight, equalling the sepals. — 

 Wet open ground near Epperson's, Lake Co., 3Irs. Curran. July.

 or less pubescent: fl. few and large (1)2 in. broad), on long ascending
