This species occurs in rich upland woods, flowering in 

 April and May, and common only locally. Our present in- 

 formation limits this species in our state to the northeast 

 quarter. Many botanists have considered this species as 

 identical with the European Anemone nemorosa L. Our 

 species is said to differ much in aspect from the European 

 one, having smaller flowers, slender petioles, and the divi- 

 sions of the involucral leaves less lobed.
