Form

A large tree with a tall, often graceful trunk, averaging 50 to 80 feet in height and up to 24 inches in diameter. The crown is rounded to pyramidal.

Bark

Dark and nearly smooth on young twigs and branches, and greenish-brown on older trees. Narrow ridges are separated by deep, diamond-shaped fissures arranged with marked regularity.

Leaf

Leaves are opposite on the stem, 8 to 12 inches long, and pinnately compound with five to nine plainly stalked, sharp-pointed leaflets. The upper surface is dark green and smooth, while the underside is pale green or whitish. Leaves turn yellow or purple in autumn.

Fruit (seed)

The winged samara is 1 to 2 inches long, resembling a canoe paddle blade with the seed toward the handle end. Seeds mature in autumn and are effectively distributed by the wind.

Range

Found only in the southeastern part of the state, this species grows best in rich soil and is intermediate in shade tolerance.

Wood

The wood is light brown, close-grained, heavy, tough, and elastic. It is preferred for making tool handles and athletic and sports equipment, and is also used for agricultural implements, furniture, interior finishes, posts, ties, fuel, and ornamental purposes.
