   The wood of the {Maclura tinctoria}, a tree growing in the

   [1913 Webster]

   Note: Other kinds of yellow wood are often called fustic; as
         that of species of {Xanthoxylum}, and especially the
         {Rhus Cotinus}, which is sometimes called young fustic
         to distinguish it from the {Maclura}. See {Fustet}.
