FNA3: "Planted for quick-growing windbreaks, Ulmus pumila 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. Ulmus pumila is similar to U . parvifolia Jacquin with its small, singly serrate leaves. Ulmus parvifolia , however, has smooth bark that sheds from tan to orange, and it flowers and sets fruit in the fall."
