Status:

Post Oak occurs on dry, sterile, upland clay and sandy soil, from Massachusetts south to Florida, west to Texas, north to Iowa, and east to Pennsylvania (Stein, et al., 2003).

Fairly common from Allegany County eastward into the Coastal Plain. One of the few tree species on the shale barrens of Allegany County and the serpentine barrens near Baltimore (Brown and Brown, 1972). In the Great Falls area of Montgomery County, Maryland, Post Oak is common on the bedrock terrace but rare on the surrounding upland (Reed, et al., 1980).

Description:

The central pair of lobes of the leaf are generally longer and much broader than the others, giving the leaf a cross-like shape.

Where to find:

Post Oak is common in Green Ridge State Forest and Soldiers Delight Serpentine Barrens.

Relationships:

Host plant for the Buck Moth and Ashy Meganola Moth.
