(A) Bayesian phylogram of AFLP phenotypes of Ranunculus pygmaeus, inferred with MrBayes. Branch lengths are mean lengths estimated from 30 002 trees after an initial burn-in phase of 10 000 trees. Numbers above branches are Bayesian posterior probabilities (only those >0.5 are shown). Samples beginning with ‘LG09’ indicates those samples used in our crossing experiments, whereas the remaining samples were re-analysed from Schönswetter et al. (2006). (B) Principal co-ordinate analysis of AFLP phenotypes observed in R. pygmaeus based on Dice’s coefficient of similarity. The percentage of variation explained by each axis is indicated. Symbols identify the main geographic regions.
