Japanese Elm Video Stock Footage
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 are obovate to obovate-elliptic < 10 cm (4 in) × < 5 cm (2 in), with a rough upper surface, often dark red on emergence. 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. There are no known cultivars of this taxon, nor is it known to be in commerce beyond the United States.
