This species is a deciduous shrub or tree usually growing 10–20 meters (33–66 ft) tall, but known to reach 35 meters (115 ft) at times. The leaves are variable in shape, even on one individual. The blades may be lobed or unlobed, but they usually have toothed edges, lightly hairy, pale undersides, and a rough texture. They are up to about 15–20 centimeters (5.9–7.9 in) long. The species is dioecious, with male and female flowers on separate plants. The staminate inflorescence is a catkin up to 8 centimeters (3.1 in) long with fuzzy male flowers. The pistillate inflorescence is a spherical head up to about 2 centimeters (0.79 in) wide with greenish female flowers trailing long styles. The infructescence is a spherical cluster 2–3 centimeters (0.79–1.18 in) wide containing many red or orange fruits. Each individual protruding fruit in the cluster is a drupe.
