Herkogamy and mate diversity in the wild daffodil Narcissus longispathus: beyond the selfing-outcrossing paradigm in the evolution of mixed mating.

Abstract excerpt

Spatial separation of male and female reproductive structures (herkogamy) is a widespread floral trait that has traditionally been viewed as an adaptation that reduces the likelihood of self-pollination. Here we propose that increased herkogamy may also influence another important aspect of plant mating: the diversity of pollen donors siring seeds within fruits. We test this hypothesis in Narcissus longispathus,...
