Flowers of females from some species of dioecious flowering plants produce dysfunctional anthers or infertile pollen. Their cryptic dioecy has frequently been mistaken for androdioecy. Earlier insights into androdioecy were drawn from sexual allocation theory. However, several cryptically dioecious taxa share a common pollination syndrome, including nectarless but showy flowers that bear yellow, often porose anthers. These flowers are visited solely by female bees seeking pollen. For these cases, cryptic dioecy is explained by pollinator foraging behavior and not sexual allocation theory. Pollen as a nutritional reward to foraging bees is largely overlooked in current studies of pollination and foraging ecology
