|discussion=<p><i>Ulmus serotina</i> is infrequent, and few populations are found outside of Tennessee. It reputedly is highly susceptible to Dutch elm disease (W. H. Duncan and M. B. Duncan 1988), and it is sometimes cultivated. <i>Ulmus serotina</i> hybridizes with <i>U. crassifolia</i>, and plants have been informally designated U. arkansana, an unpublished name. In Arkansas and Oklahoma where hybrid swarms are common, specimens are often difficult to assign to either taxon.</p>
