Ulmus laevis var. celtidea
Rogowicz

The European White Elm U. laevis var. celtidea Rogowicz was first described by Rogowicz (Fl. Kief. 229 1869), who found the tree in 1856 near Chernihiv, (syns. Chernigof, Chernigov) in what is now northern Ukraine. The leaves were oblong-lanceolate, but only about 25 mm 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. Similar trees were later found near Briansk in the Orel Province, but featured larger leaves (Chitrovo, in Bull. Soc. Nat. Orel i. 50 1907). One specimen grown at the Strona Arboretum [1], 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.
