[Buck, a beech tree ; and wheat.] A plant of a family which includes knot-weed, called also Saracen wheat, with a triangular seed shaped like beech-nuts; when ground it is used in America for griddle cakes, in France for bread or as gruel. In England it is sown as food for pheasants, to decoy them from their covers. Its flowers yield excellent honey, of which bees are very fond, and it is often planted in the United States for this purpose.
