American Elm
Ulmus americana
Ulmaceae

Leaves are simple, alternate, deciduous, doubly serrate, ovate, smooth to rough, up to 7 inches long and often with a greatly unequal leaf base. Twigs are red-brown and mostly hairless with black-red striped ovoid buds. Bark is gray with interlacing ridges and brown-white inner bark. Fruit is a deeply notched, round and hairy samara. The elms display a vase-shaped form. Before American elm's distribution was reduced by Dutch Elm disease, American elm was widely distributed throughout the east and central U.S. and was a well-loved shade tree. Form is up to 38 m (125 ft) in height and 1.5 m (5 ft) in diameter, with drooping branches and a forked or vase-shaped trunk.
