Anemone virginiana L. Sp. PL, p. 540. 1753. 



Stem slender, rather stout, branching at the involucre, 

 2-3 feet high, pubescent; involucral leaves 3, 3-parted, the 

 divisions ovate-lanceolate, cleft and serrate; the first pe- 

 duncle naked, the later with a 2-leaved involucel near the 

 middle ; sepals 5 ; head of fruit oval to oblong, achenes 

 compressed, woolly, tipped by the subulate styles. 



This species occurs in woods, blooming from June until 

 August. It is of frequent occurrence and widely distribu- 

 ted within our limits. At the close of the season the heads 

 of fruit loosen and the woolly pubescence spreads to the 

 wind which is also characteristic of Anemone cylindrica 

 Gray. This pubescence is commonly known as birds' cot- 

 ton. 



Our specimens are from Winneshiek, Allamakee, Musca- 

 tine, Jefferson, Johnson, Appanoose, Decatur, Ringgold,
