Ulmus alata (Winged Elm) is a small to medium-sized deciduous tree with a relatively short trunk and an open-rounded canopy. The bark is gray-brown with flat ridges separated by irregular fissures. The alternate, ovate, doubly serrate, dark green leaves are quite small, 2.5 in. long (6 cm). The foliage turns a dull yellow in the fall. The twigs and small limbs of Winged Elm often have corky ridges extending down either side. Inconspicuous brownish-green catkins appear in spring before the leaves emerge. They give way to single-seeded, flat, disk-like, reddish brown samaras. Native to eastern and central North America, Winged Elm occurs in dry woodlands, in rocky woods, on rock outcrops, along fence rows, and in hardwood or mixed hardwood/pine forests. A fast grower, Winged Elm is occasionally planted as a shade or street tree. Like other elms, Winged Elm has some vulnerability to the Dutch Elm disease but appears more resistant than American Elm (Ulmus americana).
