 A valuable approach to understanding the evolution of gender dimorphism involves studies of single species that exhibit intraspecific variation in sexual systems. Here we survey sex ratios in 35 populations of Wurmbea biglandulosa, previously described as hermaphroditic. We found pronounced intraspecific variation in sexual systems; populations in the northeastern part of the species' range were hermaphroditic, whereas other populations were gynodioecious and contained 2–44% females… CONTINUE READING
