Nutmeg \Nut"meg\, n. [OE. notemuge; note nut + OF. muge musk, of
   the same origin as E. musk; cf. OF. noix muguette nutmeg, F.
   noix muscade. See Nut, and Musk.] (Bot.)
   The kernel of the fruit of the nutmeg tree (Myristica
   fragrans), a native of the Molucca Islands, but cultivated
   elsewhere in the tropics.
   [1913 Webster]

   Note: This fruit is a nearly spherical drupe, of the size of
         a pear, of a yellowish color without and almost white
         within. This opens into two nearly equal longitudinal
         valves, inclosing the nut surrounded by its aril, which
         is mace. The nutmeg is an aromatic, very grateful to
         the taste and smell, and much used in cookery. Other
         species of Myristica yield nutmegs of inferior
         quality.
