Rape \Rape\, n. [L. rapa, rapum, akin to Gr. ?, ?, G. r["u]be.]
   (Bot.)
   A name given to a variety or to varieties of a plant of the
   turnip kind, grown for seeds and herbage. The seeds are used
   for the production of rape oil, and to a limited extent for
   the food of cage birds.

   Note: These plants, with the edible turnip, have been
         variously named, but are all now believed to be derived
         from the {Brassica campestris} of Europe, which by some
         is not considered distinct from the wild stock ({B.
         oleracea}) of the cabbage. See {Cole}.

   {Broom rape}. (Bot.) See {Broom rape}, in the Vocabulary.

   {Rape cake}, the refuse remaining after the oil has been
      expressed from the seed.

   {Rape root}. Same as {Rape}.

   {Summer rape}. (Bot.) See {Colza}.
