A small- to medium-sized deciduous tree endemic to the woodlands of the southeastern and south-central United States. As its common and scientific names imply, Ulmus alata is most easily recognized by the very broad, thin pair of corky wings that form along the branchlets after a couple of years. The tree generally grows to a maximum height and breadth of about 13 × 13 m. Its growth rate is often very slow, the trunk increasing in diameter by < 5mm (0.2 in) per annum.
The species is occasionally considered a nuisance as it readily invades old fields, forest clearings, and rangelands, proving particularly difficult to eradicate with herbicides. Ulmus alata is tolerant of a wide range of soils, and of ponding, but is the least shade-tolerant of the North American elms.
Spotted in previously cleared/disturbed lot between industrial complex and uncultivated wetlands/drainage area.
