A tree of up to 30 m tall. Often easily recognisable by its pale brown to reddish-brown bark which is patchy because it peels off in long pieces (Neo et al., 2016).
The lance-shaped or elliptic leaves are quite narrow, thin in texture, and are red when young. The flowers are usually deep red, but they can also be pink or orange.
This tree produces a timber which is known by the trade name derum and is moderately hard and moderately heavy to heavy (Wong, 1995). Derum is used for medium to heavy construction, and has been used to make tool handles, wood pallets, and woodcuts. Other parts of the plant are also of value as the young fruit can be used as a spice for cooking, while the twigs, bark, and roots have been used to treat colds and diarrhea (eFloras, 2008).

The young leaves are red, making for a distinctive and attractive foliage.
The leaves are narrow with faint but visible veins on the underside.
