Catkin



Catkin, reproductive organ of many common trees. Each catkin bears a cluster of primitive flowers that lack petals and sepals. Instead, the stamens and pistils are protected by small leaves called bracts. 1 Catkin bears either male or female flowers. Plants bearing catkins include beech, birch, walnut, and willow families.
