Wallaba is a hardwood species native to the forests of Guyana. This light red to reddish-brown wood is extremely dense, with a coarse, straight-grained texture. Wallaba contains high levels of gum exudates and oily resin, which help it resist insect attacks and decay. Wallaba is primarily used for shingles and transmission poles, but other uses include railroad ties, industrial flooring, decking, and fence posts.
