Transference of function in the pollination system of the Ochnaceae

Abstract

Most members of the Ochnaceae possess poricidal anthers that are emptied by pollen collecting bees performing vibrational foraging. In several genera, such as Tyleria, Adenarake, and various species of Sauvagesia, however, pollen is released by vibration from the anthers through the porus of a novel structure formed by staminodia. These envelop the androecium and gynoecium. Anthers enclosed in this envelope are often longicidal. © 1991 Springer-Verlag.
