Iroko, often also called Kambala, is one of the most common wood species in Africa. The tree can grow up to 45 meters tall and reach a diameter of 2 meters. The heartwood ranges from grey to greenish-yellow, sometimes also brown, depending on its origin. When exposed to light, the heartwood darkens, creating a golden-brown to dark olive-brown colour with a matte sheen. Although Iroko is not related to oak or teak and does not look similar to them superficially, it is often used as a substitute for these wood species.
