vinifera}, and is a native of Central Asia. Another
variety is that yielding small seedless grapes commonly
called Zante currants. The northern Fox grape of
the United States is the V. Labrusca, from which, by
cultivation, has come the Isabella variety. The
southern Fox grape, or Muscadine, is the {V.
vulpina}. The Frost grape is V. cordifolia, which
has very fragrant flowers, and ripens after the early
frosts.
