SUMMARY After cross‐pollination of self‐incompatible Diplotaxis tenuifolia the pollen tubes penetrate the wall cuticle of the epidermal papillae and grow inside the cellulose‐pectin layer of the wall towards the base of the papillae. The tubes continue their growth in the middle lamellae of the stigmatic tissue and the intercellular spaces of the stylar transmitting tissue, both of which contain pectin.
