Lignin character and use: ring-pored wood. Air-dry density is about 0.51-0.83g/cm³, with better stability and high intensity. No obvious discrimination of the lignin-hue between the core and margin. The fresh core lignin is white or light brown, the lumber center is irregular dark brown or changed colors of brown (non-decayed), and the growth ring is obvious, with lustrous, no special taste, the straight texture, the thick structure and non-uniformity.
