Reproduction forms the link between generations and is fundamental to the evolution and ecology of organisms. During the past four decades we have witnessed an explosion of research on plant reproductive systems that has enriched the study of ecology and evolution. This impressive synthesis has in large part been led by Professor Spencer Barrett and his many students, postdoctoral fellows and collaborators. Fittingly, the idea behind this Special Issue arose from a symposium that celebrated Spencer's retirement from the University of Toronto (Canada) after 40 years, and from the recognition that as the field continues to grow it is an opportune moment to take stock of recent developments and new directions.
