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.
The English Elm
U. campestris, Linn.
The English elm is often seen in the Eastern states, planted with the American elm in parks and streets, where the two species contrast strikingly. The English tree looks stocky, the American airily graceful. One stands heavily upon its heels, the other on tiptoe. One has a compact, pyramidal or oblong head, the other a loose open one. In October the superb English elms on Boston Common are still bright green, while their American cousins have passed into "the sere and yellow leaf."
The Scotch Elm
U. montana, Linn.
The Scotch or wych elm is planted freely in parks and private grounds. It is a medium-sized tree of rather more strict habit of growth than the American elm. Before the leaves open the tree often looks bright green from a distance. This appearance is due to the winged seeds which are exceptionally large and crowd the twig in great rosettes.
One horticultural variety of this species is the weeping form known as the Camperdown elm, which arches its limbs downward on all sides, forming when full-grown a natural arbor. One often sees this tree planted on lawns of limited extent, and so near the street as to render utterly absurd its invitation to privacy. To serve that reasonable and delightful end, the tree should be planted in a retired corner of one's grounds, where an afternoon siesta may be enjoyed undisturbed.
