Leaves are essentially smooth or hairless and without bristles at the lobe tip. The flowers develop when the leaves are not fully expanded. The male flowers are yellow and develop in slender clusters 2"-3" long. Bears acorns 1/2 - 1" long with the base covered by a shallow cup. In autumn, foliage turns purplish and clings to tree until late winter. Extremely long lived. Highly valued for many building purposes.
