The bark is a smooth pale gray or yellow brown that flakes with age to expose pale bark patches with large lumps (note: not galls) which sometimes occur on older trunks and main branches. The coarse wood shows little distinction between sapwood and heartwood.
The leaves are simple, subopposite or in whorls of three, and elliptic with tapering base and apex (50 x 20 mm). The upper surface is usually without hairs, while the under surface has hairs. The petiole is short and stipules are absent. Inconspicuous scales cover both surfaces. The leaf's midrib and lateral veins are very conspicuous. It is deciduous to semi-deciduous, and the leaves turn yellow and red in autumn (the specific name erythrophyllum means red leaf).
The cream or yellowish, bisexual flowers are produced in dense, rounded axillary spikes, about 10 cm in diameter and up to 3 cm long. They appear after the first leaves in spring or early summer.
The 4-winged fruit are yellow to brown in colour and 10 to 15 mm in length.
