The BlackJack Oak is a member of the red oak group. The tree is medium sized (45 feet) with a bole diameter of one to two feet. The trunk has dark bark in rectangular blocks. Leaves are five to seven inches long and are leathery on top and hairy underneath. They have shallow lobes with tan scales. The acorns are more than an half-inch long with deep globe-shaped caps which have a narrow base, hairs and are loosely attached. Twigs have angled end buds which are hairy and pointed.

The growing region is from Texas to Virginia. Oak is a hardwood providing a major portion of the annual lumber in the United States. Oak trees are generally slow-growing and long-lived and tend to be relatively resistant to diseases and insects. Tannin is a major produce from oak bark.
