Planer Tree or Water Elm is a small, deciduous tree, often with sprouts near the base. Its spreading branches form a low, broad crown to 40 ft. in height. Reddish-brown, scaly, flaky bark covers the short trunk. Dull-green leaves are asymmetrically elm-like.

This distinctive and uncommon small tree is the only species of its genus; however, fossil relatives have been found in Eurasia. Dedicated to Johann Jakob Planer (1743-89), German botanist and professor of medicine.
