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.
