DistributionFerdinand Rugel collected it in 1842 from the French Broad River, but no state was indicated. Mohr (1901) claimed the collection was from NC, but without providing definite evidence. There is a specimen from Wayah Gap in Macon County, collected by A. Armstrong in 1962 (herbarium DBG) that appears to be Betula alleghaniensis.

KY, IL, and OK south to GA, AL, and MS; reportedly northern Mex.
AbundanceVery rare, if ever found in NC at all. This species is, nonetheless, on the NCNHP Watch List, as W3 -- not conclusively documented.
HabitatMoist, high pH soils of bottomlands and streamside slopes.
PhenologyAs the common name suggests, this elm surprisingly flowers mainly in September (fall season), as opposed to late winter or spring; fruits appear in November.
IdentificationIn contrast to our other elms, leaf undersides are rather densely pubescent beneath. As in Winged Elm, branches often produce corky wings. Mature leaves are larger than those of Winged Elm but smaller than American and Slippery elms.
