|discussion=<p><i>Ulmus pumila</i> probably occurs in Vermont and West Virginia, but it has not been documented for those states.</p><!--
--><p>Planted for quick-growing windbreaks, <i>Ulmus pumila</i> has weak wood, and its branches break easily in mature trees. It is easily distinguished from other North American elms by its singly serrate leaf margins. <i>Ulmus pumila</i> is similar to <i>U. parvifolia</i> Jacquin with its small, singly serrate leaves. <i>Ulmus parvifolia</i>, however, has smooth bark that sheds from tan to orange, and it flowers and sets fruit in the fall.</p>
