A small to medium-sized, deciduous tree usually 1520 m. (5065
ft.) tall when fully grown. Bark of mature trunks is furrowed and
ridged, sometimes with small plates, becoming deeply furrowed with
age. Young twigs are typically green. Leaves are opposite and pinnately
compound, most often with 35 (occasionally 79) leaflets.
Leaflet margins usually have scattered, coarse teeth or small lobes,
especially on the portion toward the leaf tip, but may also be entire.
Male and female flowers occur on separate trees. As with other maples,
fruits consist of two, winged samaras that split apart when mature
and travel on the breeze as they spin to the ground.
