(A) Effects of floral display size on the mean number of seeds sired or mothered by each open flower (mean ± s.e.); n = 15 plants per data point. (B) Effects of floral display size on the mean number of seeds sired or mothered by all displayed flowers on a plant (mean ± s.e.); n = 15 plants per data point. Values for seeds sired per displayed flower are back-transformed from ln-transformed LS mean and s.e., and statistical tests in the text were based on ln-transformed values to meet assumptions of the analysis. (C) Effect of floral display size on the functional gender of individual plants (mean ± s.e.). Functional genders below 0·5 indicate higher reproductive success through male function than through female function; n = 15 plants per data point.
