by Michael Kuo

Note: The red oaks of eastern North America are often difficult to identify with certainty--and the task is complicated by the fact that many of the species hybridize.

Habitat: Typically on poor soil or rocky areas; usually in mixed stands with other trees; growing in the southeastern United States.

Stature: 20-50 feet high; to 1 foot in diameter; with an open and irregular crown.

Leaves: 3-7 inches long; variable in shape but usually with 3 vague, broad lobes; bristle tipped; dark green and shiny above; pale green and finely rough or hairy below.

Bark: Dark gray to black; thick; blocky.

Acorns: Bitter; to 3/4 inches long; enclosed for 1/2 (or more) in a scaly cup.
