The Maximum Likelihood (ML) phylogram, based on ITS sequence data, showing the phylogenetic position of Aster mayangheense. Nodal support values are indicated as ML bootstrap percentages (BS) and Bayesian posterior probabilities (PP); dashes (–) denote nodes with BS < 50% or PP < 0.5. The four samples of A. mayangheense and one sample of A. saxicola are highlighted in bold.
