African walnut

Description

1) Golden yellow to reddish brown heartwood with darker streaks and veins from the Lovoa Trichilioides tree — a monoecious, evergreen indigenous to Central and Southern Africa’s tropical regions. The color of the African walnut darkens with age and exposure. The sapwood is generally narrow but can be up tp 3 inches (7.5 cm) and is clearly demarcated from the heartwood. African Walnut’s grains are typically straight or slightly interlocked — yielding good working properties — with a fine to medium, consistent texture and a fine natural luster. It often displays a ribbon-stripe figuring on quartersawn surfaces, similar to Sapele. It turns, glues and finishes well. The wood is considered moderately durable.

2) Another name for Tigerwood.
