Leaves 5-10(15) cm long, with 3–7 pairs of lobes, and a heart-shaped or lobed base. Leaf stalk of 1 cm or less. Lateral veins reach to ends of lobes and indentations. Monoecious and wind-pollinated. Female flowers, and then fruits, in clusters of 2-5 and on 5-12 cm stalk. Nuts (acorns) maturing in Sep.-Oct. are ellipsoidal in shape, c. 3.5 cm long, in cups. Banded when fresh or after soaking, they provide food for many kinds of mammal and bird. Flowering is in Apr.-May.
