Any of seven species of deciduous, nut-bearing trees of the genus Castanea (order Fagales). Chestnut trees are native to the Northern Hemisphere and have been introduced throughout the world. The nuts of chestnut trees are actually fruits, with the shells enclosing cotyledons. Trees bear both male and female flowers in late spring, but must be cross-pollinated for nut production. Nuts are borne in a spiny involucre or burr that opens to release the nuts in late fall. See also: Forest and forestry; Fruit; Nut crop culture; Tree
