(Celtis iguanaea)
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 with mostly smooth margins, the berries are juicier and sweeter, while the bark is less corky. 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. Sugarberry's range extends from the Eastern United States west to Texas and south to northeastern Mexico. It is also found on the island of Bermuda. Sugarberry occurs primarily along streams and in moist soils on floodplains. Its sweetish fruit is eaten by birds and rodents,helping to disperse the seeds. The leaves are eaten by a number of insects, for example caterpillars of the Io moth (Automeris io). Sugarberry's leaf litter contains allelopathic chemicals that inhibit seed germination and growth in many other plant species.
