Leaves are deciduous, alternate, simple, ovate to elliptical, 3-4" long, with serrated margins, bright green in summer, somewhat undulated. Leaf base is unequal. Poor fall color.
Stems are green turning brown.
Flowers are nondescript but quite interesting.
Fruit is a small 1/2" diameter fleshy drupe, orangish color.
Bark is smooth.
Misidentification: Can't say for sure, have never taught the plant so I have no feedback from students. The common hackberry (Celtis occidentalis) has broadly ovate leaves.
