Laurel \Lau"rel\, n. [OE. lorel, laurer, lorer, OF. lorier,
   laurier, F. laurier, (assumed) LL. Laurarius, fr. L. laurus.]
   1. (Bot.) An evergreen shrub, of the genus Laurus (Laurus
      nobilis), having aromatic leaves of a lanceolate shape,
      with clusters of small, yellowish white flowers in their
      axils; -- called also sweet bay.

   Note: The fruit is a purple berry. It is found about the
         Mediterranean, and was early used by the ancient Greeks
         to crown the victor in the games of Apollo. At a later
         period, academic honors were indicated by a crown of
         laurel, with the fruit. The leaves and tree yield an
         aromatic oil, used to flavor the bay water of commerce.
         [1913 Webster]

   Note: The name is extended to other plants which in some
         respect resemble the true laurel. See Phrases, below.
