base of blade flat or somewhat heart-shaped; leaf margins doubly serrate;

tip of blades coming to a point gradually or abruptly.

Flowers

All plants have separate male (staminate) and female (pistillate) flowers. Male flowers are arranged sprirally along a pendulous (dangling) catkin; female flowers enclosed in bracts at the tip of the twigs with only the red stigmas visible.

Fruits
