Post Oak is a fairly common large tree that grows in drier habitats. Similar to White Oak (Q. alba) but with thicker, cross-shaped leaves, stellate hairs on the undersides of the leaves (visible with a hand lens), and less flaky bark. In the Coastal Plain, compare with the Sand Post Oak (Q. margaretta), which is smaller in stature and has less cross-shaped leaves.
