baobab , Tree (Adansonia digitata) of the mallow family (Malvaceae), native to Africa. The barrel-like trunk may reach a diameter of 30 ft (9 m) and a height of 60 ft (18 m). The large, gourdlike, woody fruit contains a tasty pulp. A strong fibre from the bark is used locally for rope and cloth. The trunks are often excavated to serve as water reserves or temporary shelters. The baobab is grown for its extraordinary shape as a curiosity in areas of warm climate, such as Florida. A related species, A. gregorii, occurs in Australia, where it is also called a bottle tree.
