  • Underlining indicates probabilities that are greater with a P. amoena/P. cyanea species topology than with a P. amoena/P. caerulea species topology. Italic numbers indicate the opposite pattern. All probabilities calculated using COAL (Degnan and Salter 2005).

  • a NJ gene tree search based on Tropo6 sequence data produced an unresolved topology and was dropped from COAL analyses.

  • b Species names abbreviations: Pam, P. amoena; Pcy, P. cyanea; Pca, P. caerulea; Pro, P. rositae; Ccy, C. cyanoides. Numbers following species abbreviations in NJ topologies refer to the different individuals sampled. All species were constrained to be monophyletic in the species topologies.
