Laurel, Prunus laurocerasus, a common plant in UK gardens and parks possesses extrafloral nectaries that attract insects, particularly honeybees and wasps. Nectaries are located at the base of the leaf blade close to the petiole and consist of thickened layers of secretory cells forming raised bumps of tissue. Although not involved in pollination they do attract insects which might also pollinate the flowers (in many plants with these structures they attract insects, such as ants, that help defend the plant against herbivors).
