Mean effect sizes of floral integration for selfing, mixed and outcrossing species for the whole set of species surveyed. Bars around the mean denote standard deviations All mean effect sizes were significant since their confidence intervals did not overlap with zero. Numbers in parentheses indicate the sample size for each mating category. (A) Phenotypic integration of the whole set of morphometric floral traits. (B) Phenotypic integration of sexual organs (androecium and gynoecium). (C) Phenotypic integration of perianth traits (calix and corolla).
