Allspice \All"spice`\, n.
   The berry of the pimento ({Eugenia pimenta}), a tree of the
   West Indies; a spice of a mildly pungent taste, and agreeably
   aromatic; Jamaica pepper; pimento. It has been supposed to
   combine the flavor of cinnamon, nutmegs, and cloves; and
   hence the name. The name is also given to other aromatic
   shrubs; as, the {Carolina allspice} ({Calycanthus floridus});
   {wild allspice} ({Lindera benzoin}), called also {spicebush},
   {spicewood}, and {feverbush}.
