Rape \Rape\, n. [L. rapa, rapum, akin to Gr. "ra`pys, "ra`fys,
   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

   the food of cage birds.
   [1913 Webster]

   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
         (Brassica oleracea) of the cabbage. See Cole.
