Juglans australis wood is dense (640 kg/m), hard, and strong. Upon drying, the radial shrinkage is 2.2%, the tangential 4.7%. The pinnately compound leaves are borne alternately, and bear up to fifteen oval-lanceolate finely serrate leaflets. The immature fruits are pickled whole for human consumption. The mature nuts are also eaten. Like most walnuts, "J. australis" produces juglone, an allelopathic substance which decreases competition from other plants growing nearby. The concentrated extract of the husk is also used as a vermifuge. Juglans australis Juglans australis, the nogal criollo, is a species of plant in the Juglandaceae family.
