Vetch \Vetch\, n. [Also fitch; OE. ficche, feche, for veche, OF.
   veche, vecce, vesche, vesce, F. vesce, fr. L. vicia.] (Bot.)
   Any leguminous plant of the genus {Vicia}, some species of
   which are valuable for fodder. The common species is {V.
   sativa}.

   Note: The name is also applied to many other leguminous
         plants of different genera; as the chichling vetch, of
         the genus {Lathyrus}; the horse vetch, of the genus
         {Hippocrepis}; the kidney vetch ({Anthyllis
         vulneraria}); the milk vetch, of the genus
         {Astragalus}; the licorice vetch, or wild licorice
         ({Abrus precatorius}).

Tare \Tare\, n. [Cf. Prov. E. tare brisk, eager, OE. tarefitch
   the wild vetch.]
   1. A weed that grows among wheat and other grain; -- alleged
      by modern naturalists to be the {Lolium temulentum}, or
      darnel.

            Didst not thou sow good seed in thy field? From
            whence then hath it tares?            --Matt. xiii.
                                                  27.

            The ``darnel'' is said to be the tares of Scripture,
            and is the only deleterious species belonging to the
            whole order.                          --Baird.

   2. (Bot.) A name of several climbing or diffuse leguminous
      herbs of the genus {Vicia}; especially, the {V. sativa},
      sometimes grown for fodder.
