Fig 1.
The cladogram of the maximum likelihood (ML) tree from the combined data (ITS, ETS and trnL-F), showing the position of Aster tianmenshanensis.
Values above branch represent bootstrap values (BS) for maximum likelihood and Bayesian posterior probabilities (PP) respectively; the dash (–) indicates BS < 50% or PP < 0.90. The new species is indicated by shading and its putative relatives in bold. Taxonomic treatments in Flora of China are illustrated with color bars. The type species Aster amellus is indicated in brackets. Species with unequal lobes are shown with black dots.
