VICIA, the TARE or VETCH; a genus of the de-candia order, belonging to the diadelphia class of plants. There are 18 species, the most remarkable of which is the sativa or common tare. This is so well known, that no description needs be given. It is known to be an excellent fodder for horses. In some parts of England the crop is ploughed in to answer the purposes of manure to the land. Pigeons are very fond of the seeds; and in some parts of Sweden, &c. they enter into the composition of bread, either alone, or mixed with the flour of rye.—A decoction of them in water is sometimes given by the common people in England to expel the small-pox and measles.
