Palm \Palm\, n. [AS. palm, L. palma; -- so named fr. the leaf
   resembling a hand. See lst {Palm}, and cf. {Pam}.]
   1. (Bot.) Any endogenous tree of the order {Palm[ae]} or
      {Palmace[ae]}; a palm tree.

   Note: Palms are perennial woody plants, often of majestic
         size. The trunk is usually erect and rarely branched,
         and has a roughened exterior composed of the persistent
         bases of the leaf stalks. The leaves are borne in a
         terminal crown, and are supported on stout, sheathing,
         often prickly, petioles. They are usually of great
         size, and are either pinnately or palmately many-cleft.
         There are about one thousand species known, nearly all
         of them growing in tropical or semitropical regions.
         The wood, petioles, leaves, sap, and fruit of many
         species are invaluable in the arts and in domestic
         economy. Among the best known are the date palm, the
         cocoa palm, the fan palm, the oil palm, the wax palm,
         the palmyra, and the various kinds called cabbage palm
         and palmetto.

      symbol of victory or rejoicing.
