This is the American race of V. opulus, differing from it in minor characters such as the more glabrous undersides of the leaves, the shallower, broader channel of the petiole, and the smaller, convex or club-shaped petiolar glands. It is of wide distribution in Canada and the northern USA, as far west as British Columbia and Washington. It is known in N. America as ‘cranberry’; the fruits are pleasanter to the taste than those of its Old World ally and are used to make jam.
