inches long, secondary ones an inch long, or even all but the 
central one absent; leaflets irregularly two to three-lobed and the 
lobes entire to three to five lobed or toothed, and teeth rounded 
and blunt, leaflets obovate, cuneate, or broader, one-half to two 
inches long, seldom pubescent, glaucous or paler below; lower 
stem leaves similar with shorter petiole; upper stem leaves 
without a petiole; uppermost leaves reduced to simple or three to 
five-lobed usually leafy bracts which are usually acute; the 
development of the stem leaves depends upon the exposure 
inversely. The whole plant except the leaflets is covered with 
a glandular hairy pubescence which is scarcely visible at times 
and at others is very pronounced, but is of no specific value. 
It is most pronounced on the peduncles and young pods, and is 
more evident above. The genus frequents open woods in the 
East, and stream banks and moist mountain sides at rather high 
elevations in the West. 
* Limb of petal somewhat dilated above, oblong to rhomboidal, 
large, at least half as long as the sepals, and about equaling 
the stamens, flowers not red. Petals rounded, truncate or 
emarginate. § Dilale. 
+ Stems tall, often three feet high, nearly glabrous below; 
sepals acute, spreading, rather thin, nectary small, 
++ Spurs long, straight, slender, two to four inches long, 
not shorter than sepals, nectary very small, apparently 
abortive; flowers large, one and one half to four inches 
wede, ascending; limb of fetal four to six lines wide, 
stx to ten long or even more. 
A. cerulea, James. Sepals white or lavender, lanceolate to 
broadly ovate, one to two inches long, occasionally tinged with 
pink or yellow; flowers two to four inches wide, petal-limb six to 
eight lines long, white to deep cream yellow, sepals and petals 
both frequently veined with blue, fragrant. 
Abundant in Colorado at middle elevations 7000 to 11,000 
feet altitude in all the mountains, mostly on moist mountain 
sides; very abundant in the Wasatch and Uintas at 8000 to 
10,000 feet altitude and therefore subalpine, also in the Pine 
Valley Mountains in southern Utah; less abundant south and
