Yellowwood is an even-grained, lightweight South African wood that has been used historically for hundreds of years, and a variety of purposes. It was extensively used in railway sleepers, as well as in multiple phases of construction. Its tough, durable nature saw it used as an exterior wood in the region. (It is still very popular throughout Southern Africa for indoor carpentry and floors, as it is also dimensionally stable.) The heartwood is pale yellowish brown, and not easy to distinguish from the sapwood; reddish streaks are sometimes present (in the heart). Grains are typically straight, though occasionally wavy; its texture is fine and consistent, with a nice natural luster.
