This shrub grows in dry woodlands and forest edges and can reach 8 meters tall. Although the core stems were shaded and bare, the upper branches were full of leaves.

The oldest leaves were near the bottom. They were large and a deep green, and were clearly shaded by the newer, upper leaves.

The upper leaves were a healthy light green, and the upper branches looked more like a tree than a shrub.

The leaf was a rounded oval in shape, coarsely double-toothed along its edge. The under part of the leaf felt fuzzy. The leafs were roughly 3 inches (8 cm.) long, and roughly 2 inches (5 cm.) wide.

Detail of a branch with new leaves sprouting from its joint. Flowers and nuts only appear in the spring. This was mid summer.
