lines wide, nearly truncate; anthers elliptical, one-half line 
long. Upper leaves scarcely bract-like. 
Open woods in the Eastern States. Seems to occur from 
Arizona to British America, in the Rocky Mountains rarely, at 
8000 feet altitude or higher, but all these forms may be the next 
if it is distinct which is doubtful. Also in the San Francisco 
- Mountains, Arizona Jones. May hybridize with cerulea. 
A. formosa. Fischer, DC. Prod., 1, 50. Stout spurs about 
equaling the ovate sepals, five lines long, reflexed or widely 
spreading; petal limb three lines long, as long as broad, narrower 
at apex; stamens an inch long; anthers narrowly oval. Probably 
a form of the above, though the spurs are shorter and the upper 
leaves are more bract-like. 
Along streams near the bases of the mountains, in cafions, 
6000 to 8000 feet altitude. Said to exist in Colorado, frequent 
in western Utah, Nevada, and northward to British America, 
also Oregon, not found in California. 
A. formosa, vat. truncata (Fischer & Meyer), 4. ¢runcata, 
F. & M. Ind. Sem. Petr. Supp. 8. Differing from the above 
only in the limb of the petal being reduced to a rudiment. 
Intermediate forms seem to occur. 
Along mountain streams at middle elevations in California 
and northward. May hybridize with 4. cerulea.

Aquilegia ecalcarata, Eastwood, Zoe ii, 220, two feet high, 
very slender, stems inclined to be glaucous and whole plant 
minutely and sparsely glandular pubescent; leaflets distant and 
few, on capillary stalks, sharply cuneate at base, thin, an inch 
long, veiny; peduncles four to six inches long, very slender, 
erect; bracts lanceolate-ovate, three lines long, entire; flowers 
three-quarters of an inch wide, parts delicate, thin; sepals 
closely and parallel veined, lanceolate, acute, spreading; petals 
the same as sepals but more delicate, and barely saccate at base; 
stamens just equaling the petals; anther very small, narrowly 
oval; styles barely pubescent at base, longer than usual; ovaries 
minutely glandular pubescent when young, when mature almost
