 tomentose or tawny underneath, the veins somewhat ferruginous ; fertile panicles oblong, 

 compact, rather few-flowered ; berries large. — Michx. jl. 2. p. 230 ; Pursh, fl. 1. p. 169 ;

Stem very long, straggling over bushes and shrubs, or climbing the highest trees, sometimes 

 6-8 inches in diameter near the base ; the younger branches clothed with a ferruginous 

 pubescence. Leaves usually 4 — 6 inches in diameter, sometimes much larger, often distinctly 

 3-lobed ; upper surface dark green, dull ; teeth short, mucronate. Panicles about 2\ inches 

 long ; the fertile ones less compound than the sterile. Fruit nearly three-fourths of an inch in 

 diameter, globose, usually very dark purple when ripe, but sometimes amber-color or greenish 

 white, of a strong musky odor and somewhat rancid taste, filled with a tough pulp. 



Common in woods and swamps. Fl. Early in June. Fr. September. 



Several varieties of this grape have long been cultivated, but they all have more or less of a 

 tough pulp and strong flavor : the most esteemed are the Isabella, Schuylkill or Alexander's, 

 the Catawba and Bland's Grape.

Stem very long, climbing the highest trees. Leaves 4-7 inches wide, often deeply lobed, 

 with the sinuses rounded ; the upper surface bright green, not shining ; under surface clothed
