CKOWFOOT FAMILY. 37 



A. Japdnica, Sieb. & Zucc. 2-3 high, flowering in autumn ; flowers 

 2'-3' across, rose-color or white ; leaves ternate, the leaflets variously 

 cut and toothed. Hardy. China. 



* * Wild species, smaller-flowered. 

 *- Akenes densely woolly and very numerous. 



-M. Stems single, 3'-6' high, from a small tuber; sepals 10-20 ; involucre 

 sessile. 



A. Caroliniana, Walt. Involucre 3-parted, its wedge-shaped divi- 

 sions 3-cleft, purple or whitish. N. C. west to 111. and Neb. May. 



M--W- Stems branched, 2-3 high; leaves of the involucre long-petioled, 

 compound ; sepals 5, small, greenish-white, silky beneath. 



A. cylindrica, Gray. LONG-FRUITED A. Involucre several-leaved 

 surrounding several long, naked peduncles ; flowers late in spring (in dry 

 soil N. and W.), followed by a cylindrical head of fruit. 



A. Virginiana, Linn. VIRGINIAN A. Involucre 3-leaved ; peduncles 

 formed in succession all summer, the middle or first one naked, the others 

 bearing 2 leaves (involucel) at the middle, from which proceed two more 

 peduncles, and so on ; head of fruit oval or oblong. Common in woods 

 and meadows. 



H- 1- Akenes not woolly, fewer; flower 1' broad or more. 



A. Pennaylvanica, Linn. PENNSTLVANIAN A. Stem 1 high, bearing 

 an involucre of 3 wedge-shaped 3-cleft and cut sessile leaves, and a naked 

 peduncle, then 2 or 3 peduncles with a pair of smaller leaves at their 

 middle, and so on ; flowers white in summer. (Lessons, Fig. 233.) Allu- 

 vial ground, N. and W. 



A. nemor6sa, Linn. WOOD A. Stem 4'-10' high, bearing an invo- 

 lucre of 3 long-petioled leaves of 3 or 5 leaflets, and a single short-pedun- 

 cled flower ; sepals white, or purple outside. Woodlands, early spring. 



3. HEPATICA, LIVERLEAF, HEPATICA. (Shape of the leaves 

 likened to that of the liver.) Among the earliest spring flowers. 

 Stemless low ^, with 3-lobed leaves and 1 -flowered scapes. The 

 involucre is so close to the flower and of such size and shape that it is 

 most likely to be mistaken for a calyx, and the six or more oblong, 

 colored sepals for petals. 



H. trfloba, Chaix. ROUND-LOBED H. Leaves with 3 broad and 

 rounded lobes, appearing later than the flowers, and lasting over the 

 winter ; stalks hairy ; flowers blue, purple, or almost white. Woods,

A. thalictroldes, Spach. RUE ANEMONE. Smooth and delicate, some- 

 what resembling Wood Anemone ; stem-leaves none, except those that
