7. A. Pennsylvanica, L. Hairy, rather low; primary involucre 3- 

 leaved, bearing a naked peduncle, and soon a pair of brandies or peduncles 

 with a 2-leaved involucre at the middle, vhich branch similarly in turn ; their 

 leaves broadly wedge-shaped, 3-cleft, cut and toothed ; radical leaves 5 - 7- 

 parted or cleft; sepals white (6-9" long) ; head of fruit spherical. W. New 

 Eng. to Penn., 111., and northwestward. June- Aug. 



* * * Achenes rather few, near!// naked, orale-oblong ; stems slender, \-Jlowered ;

8. A. nemordsa, L. (WIND-FLOWER. WOOD A.) Low, smoothish ; 

 stem perfectlv simple, from a filiform rootstock ; iiiro/ucrr of 3 lonrj-petioled tri- 

 foliolate leaves, their leaflets wedge-shaped or oblong, and toothed or cut, or 

 the lateral ones (var. (>riN<.>n .1 ui \\) 2-parted ; a similar radical leaf in sterile 

 plants solitary from the rootstock; peduncle not longer than the involucre; 

 sepals 4-7, oval, white, sometimes blue, or tinged with purple outside; carpels 

 only 15-20, oblong, with a hooked beak. Margin of woods. April, May.

3. HEPATIC A, Dill. LIVER-LEAF. HEPATICA. 



Involucre simple and 3-leaved, very close to the flower, so as to resemble a 

 calyx; otherwise as in Anemone. Leaves all radical, heart-shaped and 

 3-lobed, thickish and persistent through the winter, the new ones appearing 

 later than the flowers, which are single, on hairy scapes. (Name from a 

 fancied resemblance to the liver in the shape of the leaves.) 



1. H. triloba, Chaix. Leaves with 3 ovate obtuse or rounded lobes; 

 those of the invi >lucre also obtuse ; sepals 6-12, blue, purplish, or nearlv white ;
