A medium-sized to large tree, Celtis occidentalis. It occurs in the eastern half of the United States, except in the extreme south, and is characterized by corky or warty bark, by alternate, long-pointed serrate leaves unequal at the base, and by a small drupaceous fruit, with thin, sweet, edible flesh. Both species are used for furniture, boxes, and baskets, for shelterbelts, and as shade trees. Sugarberry (C. laevigata) is similar to hackberry and grows in the southeast United States.
