Ulmus laevis var. celtidea  Ulmus laevis" var. "celtidea Rogow. is a putative variety of European White Elm first described by Rogowicz, who found the tree in 1856 along the river Dnjepr near Chernihiv in what is now northern Ukraine. The type specimen is held at the National Herbarium of Ukraine. The variety was first named as "Ulmus pedunculata" var. "celtidea". Litvinov (1908) considered it a species, calling it "Ulmus celtidea" Litv., a view not upheld by other authorities. Similar trees were later found near Briansk in Oryol Oblast, but featured larger leaves. The leaves are oblong-lanceolate, but only about in length, long-acuminate at the apex, and coarsely, sharply serrate, cuneate and sub-equal at the base. The samarae were also notably smaller than the species   One specimen which grew at the Strona Arboretum, University of Life Sciences, Warsaw, Poland, (as "Ulmus celtidea" Litv.) died circa 2006. The tree was grown from seed collected from a tree at the Arboretum of the Forest-Technical Academy in St. Petersburg in 1961; it is not known whether this source is still alive. No cultivars or hybrid cultivars are known.
