We do not have any more information for this species, but the general description for the wood of the tropical members of this genus is as follows:-
The heartwood is chocolate-brown and generally darker than the North American black walnut (Juglans nigra), sometimes with a purplish cast; it is sharply demarcated from the whitish sapwood. The texture is rather coarse; the grain is straight to irregular; luster is high; odour and taste are mild but distinctive. The wood dries very slowly, wet zones persist, and severe honeycombing and collapse may occur in stock thicker than 10cm x 10cm. The wood works well, cutting cleanly with hand and machine tools and taking an excellent finish. It also peels and slices readily but the veneers are also reported to dry slowly. It is used for decorative veneers, furniture, cabinet work, interior finish, and other applications similar to the North American black walnut[
