Hierarchical AMOVA of British Euphrasia populations. Analyses performed between (A) taxa, (B) three geographic locations (Wales, South West England, Scotland), (C) diploids and tetraploids. Number in parentheses is the result only including species (excluding hybrids). d.f. = degrees of freedom. **P < 0.001; *P < 0.05.
