Ulmus pumila L. var. arborea Litv. |
U. pumila L. var. arborea Litv. is distinguished by its greater height and pinnate leaves. Endemic to western Siberia and Turkestan, it was introduced to the west by Georg Dieck in 1894, where it became known as U. pinnato-ramosa. The leaves are 4 - 7 cm in length, ovate-lanceolate, double-toothed and finely pointed. Var. arborea grows very vigorously, and can ultimately make a large tree.
