Quercus Muhlenbergii, Engelm
Quercus Acuminata, Sarg
Chestnut Oak
Habitat and Range.—Dry hillsides, limestone ridges, rich bottoms.
Ontario.
Vermont,—Gardner’s island, Lake Champlain; Ferrisburg (Pringle); Connecticut,—frequent (J. N. Bishop, 1895); on the limestone formation in the neighborhood of Kent (Litchfield county, C. K. Averill); often confounded by collectors with Q. Prinus; probably there are other stations. Not authoritatively reported from the other New England states.
South to Delaware and District of Columbia, along the mountains to northern Alabama; west to Minnesota, Nebraska, Kansas, Indian territory, and Texas.
Habit.—A medium-sized tree, 30-40 feet high, with a trunk diameter of 1-2 feet, attaining much greater dimensions in the basins of the Ohio, Mississippi, and their tributaries; trunk in old trees enlarged at the base, erect, branches rather short for the genus, forming a narrow oblong or roundish head.
Bark.—Bark of trunk and large branches grayish or pale ash-colored, comparatively thin, flaky; branchlets grayish-brown; season’s shoots in early summer purplish-green with pale dots.
Winter Buds and Leaves.—Buds ovate, acute to obtuse, brownish. Leaves simple, alternate; in the typical form as recognized by Muhlenburg, 3-6 inches long, 1½-2 inches wide, glossy dark green above, pale and minutely downy beneath; outline lanceolate or lanceolate-oblong, with rather equal, coarse, sharp, and often inflexed teeth; apex acuminate; base wedge-shaped or acute; stipules soon falling. There is also a form of the species in which the leaves are much larger, 5-7 inches in length and 3-5 inches in width, broadly ovate or obovate, with rounded teeth; distinguishable from Q. Prinus only by the bark and fruit.
Inflorescence.—May. Appearing with the leaves; sterile catkins 2-4 inches long; calyx yellow, hairy, segments 5-8, ciliate; stamens 5-8, anthers yellow: pistillate flowers sessile or on short spikes; stigma red.
Fruit.—Maturing the first season, sessile or short-peduncled: cup covering about half the nut, thin, shallow, with small, rarely much thickened scales: acorn ovoid or globose, about 3/4 inch long.
Horticultural Value.—Hardy in New England; grows in all good dry or moist soils, in open or partly shaded situations; maintains a nearly uniform rate of growth till maturity, and is not seriously affected by insects. It forms a fine individual tree and is useful in forest plantations. Propagated from seed.
