Type = species. Flower = Male. Per Galet (see citation): "Growing tip: felty, white with rose margin, flat, open. Young leaves: downy, bronze. Leaf: cuneiform, 136 to 146-3-24 to 57, medium, barely three-lobed (10 or 11), often with convex edges, underside cobwebby-pubescent; teeth nearly flat, convex; petiolar sinus lyre-shaped; petioles medium, green, cobwebby. Shoot: ribbed, soft, easily broken or detatched from vine, downy, sometimes lightly pubescent. Flower clusters: medium or large, winged with numerous lateral branches; male and female. Cluster: medium-large, conical, many lateral branches; berries round, small, with very little pink, acid, juice. Seeds: medium, yellowish brown to dark mahogany; very swollen dorsal side; small chalaza, posiiton .49, oval; beak short and thick; very shallow sometimes nonexistant indentations. Growth habit: vigorous, climbing...Along with V. cinerea this is the latest ripening of the American species; its vegetative cycle is approximately a month later than riparia. Budbreak is in mid-April, bloom around June 25, maturity in mid-October and leaf fall around November 20. Its resistance to phylloxera is good (16/20); the leaves carry a few galls...its resistance to lime-induced chlorosis is good...good resistance to fungus diseases and Pierce's disease."
