Leaves: Alternate, simple, ovate to nearly round, coarsely toothed, rough to the touch, leaf base rounded.
Bark: Dark gray or brown with prominent raised lenticels.
Flowers: The male catkins form in late summer and mature the following year; female catkins develop in spring and ultimately form the fruits.

Habitat: Common along streams, swamp openings, bog edges, shores; also on drier sites such as old fields and pastures, requires full sun.

Similar Species: The bark of Smooth Alder has fewer lenticels, the leaves are more finely toothed, and new leaves are marked by a sticky resin.
Comments: In the boreal forest Speckled Alder often associates with Black Spruce. Ruffed grouse feed on the buds, deer and moose browse the leaves and twigs.
