Significance of phylogenetic signal	-	*	**	*	*	**	**	-	**

1) Chromosome numbers were taken from previous studies ([68]: E. palustris, E. waltersii; [49]: E. sterneri because of sample identity; [69]: E. quinqueflora because of population identity; [35]: E. interstincta). For the remaining samples, chromosome numbers were counted by O. Rotreklová and P. Bureš (unpublished data).

2) An average of seven samples, each representing a different population (see Results and Discussion).
