Flowering plants show an astonishing diversity of flower shapes and colours. Among plant reproductive systems, dioecy is of particular interest because each sex can be subjected to independent selection pressures that may lead to the evolution of different floral traits in the two sexes (sexual dimorphism; chapter 1). On the one hand, many studies have confirmed the role of pollinators as...
