Bayesian and ML-based phylogenetic tree inferred from nuclear internal transcribed spacer (ITS) of the 51 sampled taxa identified as species of Euonymus and/or Glyptopetalum. Values above branches are Bayesian posterior probabilities (> 0.5) / maximum likelihood bootstrap percentages (> 50). Colors of terminal nodes correspond to the five sections of Euonymus defined in Flora of China (Ma et al. 2008) and the genus Glyptopetalum.
