The leaves are triangular with irregular teeth along the edge. They are 10 cm long. They taper at the base and are pointed to the tip. There are hairs on the veins underneath. The male and female flowers are on catkins on the same tree. Male catkins are 7.5 cm long and yellow-brown and hang down. Female catkins are green and upright. The fruit is a catkin which breaks up when ripe.
