 30-70 cm. tall, appressed-puberulent at least above with white usually curved 

 hairs; leaves 3-7-parted, the divisions usually deeply cleft into 2-4, usually 

 3 lobes, the segments linear or lanceolate; petioles mostly exceeding the blades; 

 racemes loose, 5-25-flowered; pedicels spreading, mostly as long as or longer 

 than the dark blue flowers; sepals pubescent on the outside, 2-2.5 cm. long; 

 spur as long, mostly acute and slender; follicles 3, mostly diverging at maturity, 

 pubescent, 1.4-3 cm. long. 



In open grassy places. Originally collected by Menzies, probably at Nootka 

 Sound.

 1-2 m. high, smooth and glaucous; leaves orbicular, 5-7-parted, the lobes 

 laciniately toothed and acuminate, dark green above, pale beneath; flowers 

 pale, dull blue, in a dense raceme; pedicels short; sepals 10-12 mm. long; 

 follicles glabrous, veiny. 



Along streams in the mountains.

 5-7-cleft or parted, the lobes cuneate, incisely cleft into lanceolate acute lobes; 

 raceme loosely many-flowered, the pedicels spreading; flowers dark blue; 

 sepals 1.5-2 cm. long, ovate, acuminate; follicles glabrous, turgid, veiny, 

 recurved when mature, 12-15 mm. long. 



In meadows along streams, Lewis County, Washington, to northern Calif- 

 ornia. Commonly reputed to be very poisonous to cattle.
