6. A. Virginiàna, L. More loosely pubescent or glabrate; involucral leaves 3, 3-parted; their _divisions ovate-lanceolate_, pointed, cut-serrate, the lateral 2-parted, the middle 3-cleft; peduncles elongated, the earliest naked, the others with a 2-leaved involucel at the middle, repeatedly proliferous; _sepals 5_, _acute_, greenish (in one variety white and obtuse); _head of fruit oval or oblong_.--Woods and meadows; common. June--August.--Plant 2--3° high; the upright peduncles 6--12´ long. [*][*] _Achenes naked, orbicular, compressed, wing-margined; sepals 5, obovate; involucre sessile._ 7. A. Pennsylvánica, L. Hairy, rather low; primary involucre 3-leaved, bearing a naked peduncle, and soon a pair of branches or peduncles with a 2-leaved involucre at the middle, which 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., Ill., and northwestward. June--Aug. [*][*][*] _Achenes rather few, nearly naked, ovate-oblong; stems slender, 1-flowered; leaves radical._ 8. A. nemoròsa, L. (WIND-FLOWER. WOOD A.) Low, smoothish; stem perfectly simple, from a filiform rootstock; _involucre of 3 long-petioled trifoliolate_ leaves, their leaflets wedge-shaped or oblong, and toothed or cut, or the lateral ones (var. QUINQUEFOLIA) 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.--A delicate vernal species; the flower 1´ broad. (Eu.) 9. A. nudicaùlis, Gray. Glabrous, rootstock filiform; radical leaves reniform, 3-parted, the divisions broadly cuneate with rounded crenate-incised or -lobed summit; involucre of a single similar petiolate leaf or wanting; achenes glabrous, tipped with a slender-subulate hooked style.--North shore of Lake Superior near Sand Bay, Minn., in bogs. (_Joseph C. Jones._) Imperfectly known. 3. HEPÁTICA, 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. tríloba, Chaix. Leaves with 3 ovate obtuse or rounded lobes; those of the involucre also obtuse; sepals 6--12, blue, purplish, or nearly white; achenes several, in a small loose head, ovate-oblong, pointed, hairy.--Woods; common from the Atlantic to Mo., Minn., and northward, flowering soon after the snow leaves the ground in spring.
