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.
