Bayesian 50% majority-rule consensus tree based on four plastid markers (rps4-trnLF, trnK-matK, rpl16 and petD). Values above branches in bold are posterior probabilities (PP), values in italic are bootstrap support (BS) and Jackknife support (JK) is below the branches. Values in square brackets represent a conflict in the topology of the Bayesian analysis with maximum likelihood or Bayesian analysis with parsimony. The species name at the tip of the node is preceded by its DNA number and followed by the country of origin of the sample.
