AQUILEGIA CANADENSIS L. Sp. PI. p. 533. 1753. 



A perennial herb, 1-3 feet high, branched; leaves ternately 

 compound, long-petioled, leaflets lobed; flowers solitary, 

 showy, scarlet, nodding; sepals 5, petaloid; petals 5, pro- 

 longed backward into long hollow spurs ; stamens numer- 

 ous, exserted; pistils 5 ; follicles 5, erect, slightly spread- 

 ing, tipped with a filiform beak, many-seeded. 



A rather showy plant, common in our woodlands, pre- 

 ferring calcareous soil. It is not infrequently cultivated and 

 should be preferred to the European species. The flowers 

 appear during April, linger through May and June, and 

 pass out the latter part of June or in the early part of July. 

 The range of this species as given by Britton and Brown 

 is: "Nova Scotia to the Northwest Territory, south to 

 Florida and Texas." It has a vertical range of more than 

 four thousand feet. 



Specimens before us are from Winneshiek, Fayette, Mus- 

 catine, Johnson, Decatur, and Shelby counties. The State 

 University herbarium has specimens from the additional 

 counties of Henry, Mahaska, Winnebago, Lyon, Story, 

 Jones, Calhoun, Polk, and Cerro Gordo counties. We 

 have observed the species in Allamakee, Clayton, Du- 

 buque, Scott, Des Moines, Van Buren, Ringgold, Page, and 

 Pottawattamie counties. Prof. Pammel reports the species 

 from Hamilton county and Prof. Bessey from Floyd and Powe- 

 shiek counties. In all probability there is not a county in
