Celtis laevigata
（重定向自Sugarberry）
Celtis laevigata is a medium-sized tree native to North America. Common names include sugarberry, Southern hackberry, or in the southern U.S. sugar hackberry or just hackberry.
Sugarberry is easily confused with common hackberry (C. occidentalis) where the range overlaps. Sugarberry has narrower leaves which are smoother above. The species can also be distinguished by habitat: where the ranges overlap, Common Hackberry occurs primarily in upland areas, whereas Sugarberry occurs mainly in bottomland areas.
