We compared the amount of variation in flower size between autogamous and insect‐pollinated species to examine the hypothesis that pollinator‐mediated selection stabilizes flower size in plant populations. One would expect the flower size variation to be larger in selfing species that are less affected by pollinator‐mediated stabilizing selection than in insect‐pollinated species. The results of phylogenetic comparisons between autogamous and insect‐pollinated flowers supported the pollinator‐mediated stabilizing selection hypothesis, although the non‐phylogenetic comparison did not. According to our results, we discuss the factors influencing the flower size variation.
