Adansonia \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, Adansonia digitata, the baobab or monkey-bread of
   Africa and India, and Adansonia 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.
