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 ccsrutea. 



A. formosa. Fischer, DC Prod., i, 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 canons, 

 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, var. trimcata (Fischer & Meyer), A. trimcaia^ 

 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 A. cceridea. 



^ ^ ^ Spurless; leaves triternate, floicers white or pink. 

 Peduncles very long. § Pseiidaqidlegia. 



Aqicilegia 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
