A deciduous tree up to 80 ft high, with a trunk occasionally a yard in diameter; young shoots downy. Leaves ovate to oval, often with a short, slender, drawn-out apex, obliquely unsymmetrical at the base, rather evenly doubly-toothed, 2 to 412 in. long, 114 to 212 in. wide, veins in sixteen to twenty-two pairs, parallel, those in the centre of the leaf forking towards the margin, dark green and very harsh to the touch above, paler and downy beneath, especially on the midrib and veins beneath; stalk stout, downy, 18 to 14 in. long. Samaras smooth, obovate, notched at the rounded apex of the wing, the seed situated just below the notch.

Native of W. China; discovered by Wilson in 1900; introduced by him to the Arnold Arboretum in 1910 by means of graftwood. It is related to U. japonica, but that species has leaves with usually not more than sixteen pairs of veins, also the inner margins of the notch of its samaras are edged with down. Wilson’s elm often develops corky bark after the fashion of our native U. carpinifolia.
