Leaf Margins: Doubly-serrate

The definition of doubly-serrate includes forward pointing teeth with each tooth (serration) having smaller serrations on it.

The double serration of American Elm is one of its key identification features. Its towering vase-shaped habit helps too.

The palmate leaf of the Japanese Maple (see photo at left) has clear doubly-serrate margins along every lobe.
