The BlueJack Oak is a subset member (with lobeless leaves) of the red oak group. Also known as the Sand Oak because it grows in dry coastal plains. The tree is short (30 feet) with a bole diameter of one foot. The trunk is dark with rectangular blocks. Leaves are three inches long and narrow with a point at the tip. They are shiny on top and very hairy underneath. The acorns are more than half-inch in diameter with short saucer-like caps. Twigs are woolly and have half-inch long hairy buds.

The growing region is from Texas to Carolina. 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.
