description

The lyre-leaved oak is a tree up to 30 meters high with a regularly rounded crown and often drooping branches and twigs. The bark is light gray with a slightly reddish tint and divided into thick plates. The shoots are softly hairy, but bald over time. The leaves are 10 to 16, rarely up to 20 centimeters long and 5 to 10 rarely up to 12 centimeters wide, obovate, pointed or blunt and irregularly lobed with three to four lobes on each side. Four to six pairs of nerves are formed. The upper side of the leaf is dark green and finally hairless, the underside tomentose to soft-haired. The petiole is 0.8 to 2, rarely 2.5 inches long. The light brown to gray fruits are 1.5 to 2.5 centimeters long, spherical to egg-shaped, and two thirds of them are surrounded by a hemispherical, gray-felted fruit cup on the outside .
