V. aestivalis Summer Grape. Very tall vigorous climber: leaves rusty—tomentose 
or cobwebby on under side of the large soft lobed leaves: fruit 1/3 inch in 
diameter, glabrous, black. New England to Florida and Kansas. - Norton Virginia 
grape is supposed to be a derivative. -- Hortus Second, 1941 


V. aestivalis Michx. Leaf blades-varying from broader than long to longer than 
broad, 1-3 dm in diameter, angularly or deeply 3-5-lobed, shallowly toothed, dull 
green and glabrate above, more or less densely, often unevenly, cobwebby or floc- 
culent beneath, with rusty or brown hairs, cordate: petioles usually glabrous: 
panicles 1-2.5 dm long, often conspicuously elongate and rather simple: berry 
globose, 8-10 mm in diameter, black, under a bloom, with a tough skin, and pulp 
varying from sweet to very astringent. (Summer Grape, Pigeon Grape). Thickets 
and rocky places, various vrovinces, Florida to Texas, Kansas, and New Hampshire.

Plants: Medium to tall, climbing 30 to 50 feet; branches somewhat tapering; 
tips quite naked, that is, not enveloped in slowly opening leaves, as in V. vulpina, 
Roots: Little fibrous, rather hard, penetrating, transversely wrinkled; in 
one year seedlings enlarging downward from collar. 
Wood: Cylindrical, rusty wooly when young, becoming smooth, bright reddish 
brown on maturity, with little prunose bloom near the joints and frequently on 
vigorous growing shoots thinly beset with spinous pubesence as in V._ labrusca; 
finely and evenly striated, hard and dense, less than V.Lincecumii; nodes enlarged 
under the bud, little enlarged on the opposite side; diaphragm 1/10® to 1/8" thick, 
biconcave: bud gidbose-conical, obtuse in young shoots, acute in mature, covered 
with reddish-brown scales with reddish wool at summit in expanding, medium, red 
rusty, open tip, pinkish; tendrils intermittent, once or sometimes twice forked, 
long, tomentose when young, persistent, strong; Internodes medium to long, 2" to 4" 
or even to 6" or more; pith medium, considerably enlarged at lower end, light brown. 
Leaves: Stipules small, 1/16" to 1/12" long, rather narrow, rusty wooly; 
petiole usually a little less than half as long as width of blade, cylindrical, 
obscurely striated with narrow shallow groove above, obscured with pubesence or 
rusty wool, or both; blade 4" to 7" in length, similarto V. Lincecumii in general 
outline or more cordate; basal sinus deep acute inverted V-shaped to broad V shaped, * 
approaching, sometimes lapping, generally short, obtuse or acute; often 5 rerely
