Maximum likelihood (ML) tree (-ln L=46268.63) inferred from the concatenation of 76 plastid, six mitochondrial, and three nuclear ribosomal repeat regions (cpmtnuc; Suppl. material 6​); matching the single most parsimonious (MP) tree except were dagger (†) is shown.  Tree includes 62 asterid species and 3 outgroups (Comandra umbellata, Silene vulgaris, and Silene antirrhina).  Numbers above branches indicate branch lengths used to calculate various Phylogenetic Diversity (PD) metrics.  Numbers below the branches indicate MP/ML bootstrap support values resulting from 1000 replicates each.  Low branch support (<50) is indicated by an asterisk (*).  Missing bootstrap values are denoted by a dash (-).
