Appendix C. Pearson product moment correlations among floral traits in four Argentina anserina populations in which the floral trait-pollen receipt relationship was measured.
Table C1. Pearson product moment correlations among floral traits in four Argentina anserina populations in which the floral trait-pollen receipt relationship was measured. In L1 and L2, the number of open flowers was invariable and therefore correlations were not measured for this trait (denoted by ‘−‘ ). In L1, brightness and UV chroma were not measured (denoted by ‘.’ ).

*P < 0.05, **P < 0.01, bold = significant after Bonferroni correction. ‘L’ refers to low altitude and ‘H’ refers to high altitude. UVP= UV proportion, the proportion of the petal that absorbs UV; brightness= reflectance between 300 and 700 nm; UV chroma= reflectance between 300–400 nm divided by brightness.
