Ulmus davidiana is considered to have a remarkable resemblance to the American elm (U. americana) in all but ultimate size.
The tree grows to a maximum height of 15 m (50 ft), with a relatively slender trunk < 0.3 m (1 ft) d.b.h.
supporting a dense canopy casting a heavy shade.
 Its bark remains smooth for a comparatively long time, before becoming longitudinally fissured.
The leaves, often dark red on emergence, are obovate to obovate-elliptic < 10 cm (4 in) × < 5 cm (2 in), with a minimal petiole of 2-3mm; the upper surface is rough.
The perfect, wind-pollinated apetalous flowers are produced on second-year shoots in March, followed by obovate samarae < 19 mm (3/4 in) long × < 14 mm (1/2 in) wide.
