Margosa \Mar*go"sa\, n. [Pg. amargoso bitter.] (Bot.)
   A large tree of the genus Melia (Melia Azadirachta) found
   in India. Its bark is bitter, and used as a tonic. A valuable
   oil is expressed from its seeds, and a tenacious gum exudes
   from its trunk. The Melia Azedarach is a much more showy
   tree, and is cultivated in the Southern United States, where
   it is known as Pride of India, Pride of China, or bead
   tree. Various parts of the tree are considered anthelmintic.
