Phylogenetic tree of 328 Central European native Asteraceae species. Fruit heteromorphic species are denoted with a red ‘H’ and monomorphic species with a black ‘M’. The red bars beside the letters are for species that are naturalized somewhere outside of Europe (i.e. naturalization incidence >0); blue bars are for species not known to be naturalized outside Europe. The sizes of the red bars are proportional to the log10(+2) of the number of GloNAF regions (i.e. extent of naturalization). A high-resolution version of the same tree that also shows the names of all species can be seen as Supplementary Data Fig. S1.
