F, Male sterile flowers; H, hermaphrodite flowers.

Standard deviations are given in brackets. The same superscript letter within a column indicates no significant difference between species. Comparisons between taxa were performed using one-way ANOVA followed by the Tukey–HSD test for mean pollen/flower (square root transformation) and mean ovule length (logarithmic transformation), and using the Kruskal–Wallis test followed by the non-parametric Mann–Whitney test for mean pollen viability, mean ovule width and mean corolla diameter.
