  1. F statistics (F), degrees of freedom (df), and probability (p) are given for each effect and their interactions, as are a summary of the results of post hoc Tukey’s tests (Post hoc). * Indicates a significant effect of water bath temperature. Post hoc results for measurement location are indicated by: ‘R ~ (B + E)’ indicates a significant difference (p ≤ 0.05) between the reproductive structures and the petal base as well as a significant difference between the reproductive structures and the petal edge within that species; ‘E ~ (B + R)’ between the petal edge and the petal base as well as a significant difference between the petal edge and the reproductive structures of that species; ‘–’ indicates no significant effect at that level
