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
for the production of rape oil, and to a limited extent for
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}.
