Multi-stemmed shrub 1-4 meters tall with alternate leaves. First-year twigs typically hairy to glandular, becoming glabrous (smooth) in second year.

5-10 mm long petioles with 4-10 cm long blades; base of blade flat or somewhat heart-shaped; leaf margins doubly serrate; tip of blades coming to a point gradually or abruptly.

All plants have separate male (staminate) and female (pistillate) flowers. Male flowers are arranged sprirally along a pendulous (dangling) catkin; female flowers enclosed in bracts at the tip of the twigs with only the red stigmas visible.

1.5 cm. long, hard-shelled nut enclosed within a prickly-haired tube formed by the involucre (cluster of bracts) originating at the nut base.

The nuts are often harvested shortly after ripening by squirrels and other cache-forming animals.
