Green stalk mulberry bark: 2-3 cm thick, loose texture, easy to block peeling, with milky white sap. The coat is grayish brown; it is easy to fall off in small pieces, leaving large pits. The endothelium is yellow; the phloem fibers near the surface are well developed and can be torn into hemp filaments; the stone cells are well developed, granular and distributed in the epidermis. Cross section: Heart sapwood has obvious difference. Heartwood is light brown or yellowish brown with dark stripes. The sapwood is yellow-white and 5-8 cm wide. The growth ring is slightly obvious. Macroscopic structure: porous materials. Pipe holes can be seen under the naked eye, few, slightly larger; mainly single-pipe holes, a small number of diametral multiple-pipe holes (2-3, more than 2); abundant infiltration. Axial parenchyma is distinct, well developed, wing-shaped, polypterous, and a few bands under the naked eye. Wood ray magnifier is obvious, medium density, narrow to slightly wide.

Large trees, up to 40m in diameter, up to 2.0m or more. There are only 12 species of this genus, distributed in tropical Africa, America and other regions. This species is mainly imported from Gabon, Cameroon and Equatorial Guinea, but not much.
Wood is lustrous. Typical texture staggering; uniform structure; weight, strength, shrinkage. Easy to process, easy to blunt knife; nail grip, gluing, polishing, paint performance is good. Corrosion resistance. Quick drying, slightly warped. Sawdust can irritate the skin and cause skin diseases. The air-dry density ranged from 0.62 to 0.72 cm 3.
It is suitable for cutting decorative veneers, interior decoration, ** furniture, flooring, joinery, tanned leather barrels, ships, vehicles, bridges, marine materials, etc. It can replace teak (Tectongaspp.).
