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.
