Ulmus laevis var. celtidea was 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.

Similar trees were later found near Briansk in Oryol Oblast, but featured larger leaves.
Description
The leaves were oblong-lanceolate, but only about 25 millimetres (1 in) in length, long-acuminate at the apex, and coarsely, sharpely serrate, cuneate and sub-equal at the base. The samarae were also notably smaller than the species
Cultivation
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.
