THE WINGED ELM.
U. alata, Michx.
The winged elm, or wahoo, is dainty and small, its leaves and the two thin corky blades that arise on each twig befitting the smallest elm tree in the family. Despite its corky wings, it has none of the ruggedness of the cork elm, but is a pretty round-headed tree. It is distributed from Virginia to Florida and west to Illinois and Texas.
"Mountain elm" and "small-leaved elm" are local names. "Wahoo" is local also, belonging chiefly to the South. Even the little seed of this tree is long and slender, its wing prolonged into two incurving hooks.
