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. The tree is not known to survive. Similar trees were later found near Briansk in the Orel Province, but featured larger leaves (Chitrovo, in Bull. Soc. Nat. Orel i. 50 1907).
