Overcup Oak (White Oak)
Quercus lyrata

Leaves are simple, alternate and deciduous with 5-9 smooth and irregular lobes. Twigs are smooth (but corky on older twigs) with round, pubescent buds. Bark is brown-gray and scaly. Fruit is an acorn about 1 inch long with the thin cap almost completely enclosing the dark brown nut. Acorns float in water and mature in one season. Form is up to 30 m (100 ft) in height and 1 m (3 ft) in diameter. Overcup oak is found next to streams and rivers and in flood prone areas in the southern U.S. The wood is used as white oak lumber. Acorns eaten by water fowl and many small mammals.
