sweet, but are generally austere. The river grape is distinguish- 

 able from the summer grape both by leaf characters and by the 

 later fruit which ripens with the autumn frosts. The foliage 

 has a bright green cast, the leaves having a thin, broadly heart- 

 shape depression at the base, more or less three-lobed or five-lobed, 

 with sharply cut notches, smooth and bright green below except 

 that the veins and their angles may be hairy. The leaf margins 

 are variously toothed and cut, the teeth and the long terminal 

 point of the leaf being sharply acute. The fruits are often 

 gathered for preserves or for the juice. The Clinton and some 

 other cultivated grapes are derived from this stock.
