Spatial distribution and corresponding morph type of 200 ramets per population. Coordinates (m) and the corresponding morph type (black circles: L-morph, white circles: S-morph) of all sampled ramets in a plot of 50 x 20 m in (A) one Belgian population (Waardebroeken) and (B) one German population (Bertsdorf) of P. officinalis. Genetically identical ramets are indicated with different symbols (triangle, diamond, stripe, square, cross) in black or white depending on the morph type (L or S) to which the clones belong.
