Imbuia
This species grows in Southern Brazil and is sometimes called Brazilian Walnut (but it is not a true walnut). It is a colorful, fine textured wood, prized by woodworkers. The heartwood is yellow-olive to chocolate brown, sometimes gray-brown, with variegated streaks and stripes. Grain pattern varies widely, with many different figures occurring in individual boards. Emits a spicy, resinous scent and taste.
