Flowering and flower visitors inCarludovica palmata (Cyclanthaceae) — an ecological paradoxon

Abstract

In natural habitats ofCarludovica palmata (Colombia) numerous stingless bees (Meliponinae) were observed as pollen collectors at the inflorescences and were believed to be the pollinators of the entomophilous flowers. Male flowers surround female ones on the spadix in a regular fashion. At first, the filiform, strongly scented staminodia of the female flowers unfold. After they have dropped, the anthers open, and finally the male flowers fall to ground. Only then, the stigmata of the female flowers are exposed. Previous literature references on proterogyny and the drying-up of the stigmata prior to the male phase inCarludovica are in conflict with these observations on the course of anthesis and pollination.
