A genus of great trees related to the Bombax. There are
   two species, A. digitata, the baobab or monkey-bread of Africa and
   India, and A. Gregorii, the sour gourd or cream-of-tartar tree of
   Australia. Both have a trunk of moderate height, but of enormous
   diameter, and a wide-spreading head. The fruit is oblong, and filled
   with pleasantly acid pulp. The wood is very soft, and the bark is used
   by the natives for making ropes and cloth.
