Note: The margin of the Eastern Cottonwood is a bit difficult to discern. It falls somewhere between crenate to serrate, and is even considered to be dentate in some texts. Often the description can vary because of the maturity of the leaf.

Crenate margins have rounded teeth and can vary from more fine ridges (crenulate) to the rounded teeth that you see in the Katsuratree image to the left.
