Grapevine \Grape"vine`\, n. (Bot.)
   A vine or climbing shrub, of the genus Vitis, having small
   green flowers and lobed leaves, and bearing the fruit called
   grapes.
   [1913 Webster]

   Note: The common grapevine of the Old World is Vitis
         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.
         [1913 Webster]
