Fruit.—Maturing the first season; extremely variable; sessile or short-stemmed: cup top-shaped to hemispherical, 3/4-2 inches in diameter, with thick, close, pointed scales, the upper row often terminating in a profuse or sparing hairy or leafy fringe: acorn ovoid, often very large, sometimes sunk deeply and occasionally entirely in the cup.
Horticultural Value.—Hardy in New England; in general appearance resembling the swamp white oak, but better adapted to upland; grows rather slowly in any good, well-drained soil; difficult to transplant; seldom disfigured by insects or disease; occasionally grown in nurseries. Propagated from seed. A narrower-leafed form with small acorns (var. olivæformis) is occasionally offered.
