Overcup oaks are found in the southeastern United States. They are commonly found in wet areas, such as lowlands and can grow up to 66 feet tall. The leaves of the Overcup oak have rounded lobes and the shape of the entire leaf is somewhat of an elongated-lobed oval. A distinguishing feature of the Overcup oak is the acorns. In this species the acorn cap covers more than half of the nut.
The phenology of Overcup oak helps it resist spring flooding. The leaves of Overcup oaks come out a month or more later than many other species that grow in the same areas. The flooding often kills off species whose leaves come out earlier and providing Overcucreates a competitive edge for the Overcup oaks to grow.
