Ad`an*so"ni*a\, n. [From Adanson, a French botanist.] (Bot.) 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. --D. C. Eaton.
