Populus balsamifera A. A. Reznicek

Sandy shores, dunes, and interdunal hollows; swamps and cedar swamps; often spreading vigorously in moist hollows, swamp borders, and cutover forests, forming large thickets.

The leaves of this species are rather shiny, especially when young, and rather strongly whitened or yellowish beneath. The margins of the blades, petioles, and bases of main veins are sometimes minutely puberulent, but the foliage is otherwise glabrous. Buds and twigs are reddish brown, in contrast with P. deltoides, in which they are yellowish brown.

Populus ×jackii Sarg. is an occasional hybrid of P. balsamifera and P. deltoides; it typically has foliage with hints of the whitened or yellowish color noted above for P. balsamifera, but with broad, ± deltoid leaves with the base of the blade subcordate and ± flattened petioles. It is known from Cass, Charlevoix, Cheboygan, Emmet, Gladwin, Manistee, Mason, Osceola, St. Joseph, and Van Buren Cos., and seems especially prevalent on dunes and beaches; sometimes occurring without one or both of its parents.
