Rarely exceeding 20 m in height, the tree has a rounded crown with spreading to pendulous branches. The glabrous young shoots become progressively corky-winged with age, and bear oblong to obovate leaves < 8 cm long. The flowers form pendulous racemes that open in September and serve to distinguish the species from its compatriot, the
Cedar Elm "U. crassifolia", with which it readily hybridizes. The samarae are oblong - elliptical, deeply divided at the apex, and ripen in November [http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=233501330] [http://plants.usda.gov/java/profile?symbol=ulse] .Pests and diseases
