Depending upon the climate in which it grows, the Cylicodiscus Gabunensis can be evergreen or deciduous. The cylindrical trunk is straight and reaches between 40 and 50 metres high, with a diameter ranging from 1.5 to 3 metres.

The heartwood is a rich yellow-brown colour and becomes red brown, often with a coppery glow, after exposure. The sapwood is clearly demarcated. The grain is closely interlocked and irregular, producing a beautiful stripe on surfaces. The wood is lustrous, with a medium to coarse texture.
