The Slippery Elm is a deciduous tree which can grow to 20 m in height with a 50 cm d.b.h.. The tree has a different branching pattern to the other American species, and its heartwood is reddish-brown, giving the tree its alternative common name 'Red Elm'. The leaves are 10-18 cm long and have a rough texture, coarsely double-serrate margin and an oblique base. The perfect wind-pollinated apetalous flowers are produced before the leaves in early spring, usually in clusters of 10-20. The fruit is an oval winged samara 20 mm long and containing a single, central seed. Slippery Elm may be distinguished from American Elm by the hairiness of the buds and twigs (both smooth on the American Elm) and by its very short-stalked flowers.
