Teak Iroko is golden-orange to brown; lighter vessel lines are conspicuous on flat saw surfaces. The material may contain large, hard deposits of calcium carbonate in cavities, and the timber around them may be darker in colour. The grain is interlocked and sometimes irregular, and the texture rather coarse, but even, figure mottled. The wood is somewhat greasy and is odourless. Iroko is a highly valued commercial timber in Africa, for which demand is large.
