Lignin character and use: diffuse-porous wood. Air-dry density is about 0.70-0.94g/ cm³, with better stability in lumber size, the intensity is from mid to high, and extremely anticorrosive, slightly obvious discrimination in lignin-blue between the core and margin with brown to dark chocolate, generally alternates with the dark and light stripes. The lignin margin is white or buff and some decadent deposit in the lignin core pore. The lustrous lumber is with no special taste, alternate texture, mid-degree and even structure.
