A vine climbing on various trees and shrubs in swamps, rich forests, and thickets, especially along rivers. Very local northward, along rivers such as the Au Sable, Boardman, Manistee, Menominee, Muskegon, and Pentwater. This dioecious vine is readily recognized by the peltate leaves, with petiole attached very near the margin of the ± cordate base of the blade, which is slightly pubescent along the veins beneath and usually ± shallowly (rarely deeply) lobed or with a few large teeth. The fruit is a glaucous drupe, looking rather like a wild grape, with a crescent-shaped pit.
