This elm species, also known as the cork elm due to corky ridges on branches,  is probably the least typical in form.  Rather than branching out into large co-dominant limbs, the trunk remains distinct almost to the top of the tree.  The crown is cylindrical in shape and can grow to approximately 25m in height.  A relatively rare tree, it occurs mainly in the US Midwest.  The leaves are 5-10 cm long and hairy on the underside.
