Description
Usually the Netlef Hackberry forms a small sized tree, twenty to thirty feet (6 to 10 m) in height and mature at six (15 cm) to ten inches (25 cm) in diameter, although some individuals are known up to 70 feet high. It is often scraggly, stunted or even a large bush.

Morphology

 * Bark: The bark is grey to brownish grey with the trunk bark forming vertical corky ridges that is checkered between the furrows. The young twigs are covered with very fine hairs (puberulent).
 * Leaves: The blade of the leaves are half an inch to three inches (2-8 cm) long, usually about two inches (5-6 cm). They are lanceolate to ovate, unequal at the base, leathery, entire to serrate (tending toward serrate), upper surface dark green, lower surface yellowish green, clearly net-veined, base obtuse to +- cordate, tip obtuse to acuminate, scabrous. The small stalks attaching the leaf blade to the stem (the [[petiole[[s) are generally about 5 to 6 mm long
 * Flowers: The flowers are very small averaging 1/12 of an inch (2 mm) across. They form singly, or in cymose clusters pedicel in fr 4-15 mm.
 * Fruit: 5-12 mm diameter, brownish to purple, pulp thin.
