though one to no veins branch from the secondaries near the leaf tip. The teeth on short-shoot leaves are simple, with the apical side of each tooth usually concave and the basal side usually convex. The flowers and fruits develop on fascicles at the leaf nodes of branches. The fruits are small, ranging between , with a pedicel up to long. Like species of the modern Ulmus section Chaetoptelea, the fruits do not have a surrounding wing, and the styles on the fruit apex are free. The U. sect. Chaetoptelea fruits are noted to be distinctly ciliate, having many fine hairs on the fruits, but only one fossil has been described showing ciliate, the other specimens are all smooth, possibly as a result of processes before fossilization.
