Abstract
A new and distinct variety of Ulmus parvifolia of distinct vase-shaped growth habit which resembles an American Elm in ultimate mature tree shape. The tree is characterized in having exfoliating patchy bark in attractive patterns which cover exposed bark root portions, branches over one inch in diameter and the trunk which has distinctive butresses. The tree is exceedingly durable to extremes of weather, and is resistant to common Elm pests and diseases. The tree has a dense, strong upright branching habit, with narrow but very strong branch crotch angles, and numerous thin terminal twigs which produce a dense canopy of lustrous foliage. Leaves are densely borne at the terminals of the twigs to render a full, attractive shade tree.
