Correlations between all the measured floral traits from the blue (above the diagonal) and red (below the diagonal) lineages of L. arvensis. *P < 0.01 after Bonferroni correction. Means and standard deviations were as follows: (blue flowers) style length, 2.76 ± 0.3 mm; stamen length, 2.6 ± 0.2 mm; style–stamen angle, 22.59 ± 9.3°; stigma–anther displacement; 0.16 ± 0.19 mm; n = 475; (red flowers) style length, 2.31 ± 0.2 mm; stamen length; 2.41 ± 0.2 mm; style–stamen angle, 34.43 ± 10.4°; stigma–anther displacement, −0.1 ± 0.15 mm; n = 430
