This graceful semi-deciduous to evergreen tree grows up to 15 m with an open crown and slightly drooping branches. Older trees have fissured, brown bark, while younger trees have smooth, green-red bark. The leaves are simple, alternate and taper to both ends. They are glossy, dark green above and light green below. The leaf margins are serrated. Flowers appear in short spikes with males and females on separate trees. The male spikes are dense, yellowish and can be up to 50 mm in length. The greenish coloured female spikes are shorter and thicker. The fruit is a small capsule, which splits to release seeds covered with white fluff.
