Though adaptable to most soils, the overcup oak, a Missouri native, is prevalent in the Southeastern US and in the Mississippi River Valley. In particular, the overcup oak is typically found in lowlands, floodplains, swamps and bayous. The second half of the Latin name, lyrata, means “lyre” which is most likely a reference to the shape of the leaves which are broad at the base and narrower at the tip, similar to the shape of a lyre.
