Rape, n.  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.

 Broom rape. Bot. See Broom rape, in the Vocabulary.
 Rape cake, the refuse remaining after the oil has been expressed from the rape seed.
