This species belongs to the division with simple, polyandrous male catkins, and is distinguished by its numerous ovato-lanceolate, subcordate, serrated leaflets, narrowed towards the end, somewhat downy beneath, as are the petioles; its globular scabrous fruits, and wrinkled nuts. The leaves have seven or eight nearly opposite pairs of leaflets. The male catkins are pendent. The fruits are sometimes from six to eight inches in circumference, the kernel brown and corrugated, and, although eaten, inferior to the Common Walnut. The bark of the trunk is thick, blackish, and cracked; the wood of a very dark colour.
