1. [Hamamelis virginiana] L.
Leaves obovate, acuminate, long-pointed or sometimes rounded at apex, very unequal at base, the lower side rounded or subcordate, the upper usually cuneate and smaller, irregularly and coarsely crenately lobed above the middle, entire or dentate below, when they unfold coated, especially on the lower surface of the midrib and veins and on the petioles and stipules with stellate ferrugineous pubescence, at maturity membranaceous, dull dark green and glabrous or pilose above, lighter colored and lustrous below, and pubescent or puberulous on the stout midrib and 6 or 7 pairs of primary veins, 4′—6′ long, 2′—2½′ wide; turning delicate yellow in the autumn; petioles slender, pubescent early in the season, becoming glabrous ⅓′—1′ in length; stipules lanceolate, acute, coriaceous, ⅓′—½′ long. Flowers opening from the middle of September to the middle of November; calyx orange-brown on the inner surface; petals bright yellow; ½′—⅔′ long. Fruit ripening when the flowers of the season are expanding, ½′ long, pubescent, dull orange-brown and surrounded for half its length by the large persistent calyx; seed ¼′ long.
A tree, occasionally 20°—25° high, with a short trunk 12′—14′ in diameter, spreading branches forming a broad open head, and slender flexible branchlets coated at first with scurfy rusty stellate hairs, gradually disappearing during the summer, and in their first winter glabrous or slightly puberulous, light orange-brown and marked by small white dots, becoming in their second year dark or reddish brown; usually a stout shrub sending up from the ground numerous rigid diverging stems 5°—20° tall. Winter-buds acute, slightly falcate, light orange-brown, covered with short fine pubescence, ¼′—½′ long. Bark ⅛′ thick, light brown, generally smooth but broken into minute thin appressed scales disclosing in falling the dark reddish purple inner bark. Wood heavy, hard, very close-grained, light brown tinged with red, with thick nearly white sapwood of 30—40 layers of annual growth. The bark and leaves are slightly astringent and although not known to possess essential properties are largely used in the form of fluid extracts and decoctions and in homœopathic practice, Pond’s Extract being made by distilling the bark in diluted alcohol.
Distribution. Nova Scotia, New Brunswick, and the valley of the St. Lawrence River to southern Ontario, southern Wisconsin, southeastern Minnesota and northeastern Iowa, and southward to central Georgia and southern Arkansas, growing usually on the borders of the forest in low rich soil or on the rocky banks of streams; of its largest size and probably only arborescent on the slopes of the high Alleghany Mountains in North and South Carolina and Tennessee.
Occasionally cultivated as an ornamental plant in the northern states, and in western and northern Europe.
2. [Hamamelis macrophylla] Pursh.
Leaves short-obovate or occasionally broad-elliptic, rounded, acute or rarely acuminate at apex, cuneate, rounded or cordate at the narrow slightly unsymmetrical base, crenate-lobulate above the middle with small rounded lobes, covered with short stellate hairs more abundant on the upper than on the lower surface, and at maturity dark green above, paler below, and roughened by the persistent tubercle-like bases of the stellate hairs, 3′—5′ long, 2′—3′ wide, with a slender midrib and five or six pairs of primary veins; petioles slender, pubescent, ½′—¾′ in length; stipules lanceolate, acuminate, scarious, hoary-pubescent, ⅕′—⅙′ long. Flowers opening in December, January and February; calyx yellow on the inner surface; petals light yellow, ½′ long and less than 1/24′ wide. Fruit ripening in the autumn, about ½′ in length; seed dark chestnut-brown or nearly black.
A tree, often 30°—45° high, producing stoloniferous shoots round the tall trunk often 1° in diameter, erect and spreading branches, and branchlets rusty or hoary-tomentose during their first year, becoming glabrous or nearly glabrous and grayish brown in their second season; often a shrub. Winter-buds rusty-tomentose, about ⅓′ in length.
