CROWFOOT 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. 



w 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. 



*+*+ Stems branched, 2-3 high; leaves of the involucre long-petioled, 

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



A. cyllndrica, 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- ->- Akenes not woolly , fewer ; flower I 1 broad or more. 



A. Fennsylv&nica, 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-

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

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

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

 colored sepals for petals.
