A small to large-sized, deciduous tree, typically 15–35 m (50–115
ft.) tall when mature. Bark is gray and smooth, becoming furrowed
and ridged with age, sometimes with plates. Young twigs are often
red. Leaves are opposite, and shallowly to deeply palmately lobed
(rarely unlobed). The leaf margins are irregularly serrate, with sinuses
that are sharply V-shaped, unlike those of southern sugar maple (Acer
barbatum) which are rounded. Also, the sides of terminal leaf
lobes are widest at the base, tapering to the tip, while those of
southern sugar maple are more or less parallel. Separate male and
female flowers may occur on the same or on different trees, or they
may be combined in bisexual flowers. Fruits consist of two, winged
samaras that split apart when mature, sometimes traveling long distances
on the breeze as they spin to the ground. One of the most widely distributed
native trees in eastern North America.
