Tatabu freshly cut heartwood is generally chocolate brown turning to a lighter brown when dry, occasionally grayish brown, with fine lighter parenchyma stripes; sharply demarcated from whitish or yellowish sapwood. Texture coarse; grain usually straight to slightly interlocked or slightly wavy; luster medium to high and golden, often with a waxy appearance; without distinctive odor or taste. The wood is moderately difficult to work and resulting surfaces, especially in planing, are fair to poor due to the coarse texture and frequent grain irregularity. The wood turns well and takes a good finish if filler is first applied.
