The Red Oak is the tallest of the northern oaks.  It reaches an average height of 50-80 feet, occasionally 140 feet, and has a trunk diameter of 2-6 feet.  The bark on very young trees is grayish brown and almost smooth.  The older bark is dark brown and has shallow perpendicular furrows.  The ridges are flat-topped, coarse, long, and regularly set.  The leaves have wavy edges with many pointed lobes.  They are also bristle-tipped, thin, shallowly notched, dark green or deep yellow green above and slightly paler beneath.  The leaves are smooth with white veins, and are 4-7 inches long.  The acorn is red or light brown with a shallow cup that has close scales.  The Red Oak can be found from Nova Scotia and New Brunswick south to Florida, and west to Texas.
