Ulmus prunifolia is a medium - size deciduous tree from the province of Hubei in central eastern China, where it is found at elevations of between 1000 m and 1500 m. Reaching 30 m in height, its bark is dark grey and distinctively smooth. The fairly long (< 14 cm) narrow leaves vary in shape from elliptic to lanceolate, borne on twigs devoid of corky wings or layers. The wind-pollinated petal-less flowers are produced on second-year shoots from February; the samarae are oblong - obovate < 20 mm x 13 mm, and ripen in April - May. The tree is not known to be in cultivation outside China.
