The small bells of Erica Tetralix, the cross-leaved heath, are visited vigorously by bees and many other insects. The club-like stigma lies in the mouth of the flower, the stamens hang a little further in. They dehisce by apical pores. From the basal end of each anther two spurs stick out, reaching the sides of the bell. A bee, clinging to the inflorescence, first touches the stigma ; as it pushes its proboscis past the anthers these, or their appendages, are jarred, and pollen is shaken on the insect's head.
