  • The role of geitonogamy in the evolution of inflorescence design is not well understood. The plant's dilemma hypothesis proposes that evolution of larger inflorescences is driven by selection for greater pollinator attraction, but constrained by higher rates of geitonogamy experienced by larger inflorescences. Here we investigate the role of geitonogamy on fruit set in natural populations of Asclepias speciosa. We compared fruit set from three pollination treatments: (1) inflorescences bagged… CONTINUE READING
