Ulmus procera

Morphologically similar to Ulmus ×hollandica, but distinguished by its generally smaller, round leaves, hairy stems, and columnar canopy shape. Many plants grown in Melbourne are possibly hybrids between U. procera and U. minor Miller making satisfactory determinations difficult (Spencer 1997). Furthermore, most naturalised populations of U. procera and Ulmus ×hollandica consist of suckering plants. Care needs to be taken when identifying suckering material, as leaves tend to become atypical on suckering, young or epicormic shoots. Leaf material taken from the crown is usually required to adequately identify these two species.
