An elm tree. It grows 15 m tall. It is spreading and loses many of its leaves during the year. The branches tend to hang down. The trunk has smooth bark which flakes off showing orange brown patches. It has small leaves. The leaves are narrowly oval and 6 cm long by 4 cm wide. They are unequal at the base. The leaves are pointed and have sharp teeth. They are glossy dark green above with hairs underneath. They turn yellow, red, or purple in autumn. The flowers are very small and red. They are in clusters in the axils of leaves. The fruit is a small seed with wings. It is 8 mm long.
Medium-sized tree, up to 6 m high. Stems with branchlets thinly pubescent, branches without spines. Leaves petiolate; blade elliptic to ovate, small, 25-45 x 10-20 mm long, base asymmetric, apex acute, margins serrate, leathery, glossy green on upper surface, prominently veined on lower surface, glabrous; stipules present, falling early. Flowers: inconspicuous; Mar. Fruit a flattened samara with membranous wings.
Perennial tree, 2-25 m high, bark grey, smooth. Leaves pinnately veined, ovate to elliptic, surface glossy, apex acute, up to 40 x 20 mm; petioles up to 6 mm long, glabrous. Inflorescences pendent fascicles, axillary. Perianth deeply lobed. Stamens 3-5, usually exserted; anthers reniform. Fruit a glabrous samara with 2 wings, brown, up to 8 mm long.
