Astronium

Gonçalo alves is a tropical American hardwood, sometimes referred to as tigerwood. Two species are usually listed as sources for gonçalo alves: Astronium fraxinifolium and Astronium graveolens, although other species in the genus yield similar wood. The sapwood is light in color, while the heartwood is a tan brown, sometimes with irregular dark streaks that can give the wood a dramatic appearance.  The amount of striping can vary from thin lines to bold dark strips.  The wood has superb stiffness, strength, hardness, and durability.
