Fig. 3 in Plastid phylogenomics of the Eriostemon group (Rutaceae; Zanthoxyloideae): support for major clades and investigation of a backbone polytomy

Fig. 3. Maximum-likelihood phylogeny of the Eriostemon group produced from IQ-TREE analysis of the unpartitioned 'phylogenomic' alignment of samples with full plastome data. UFboot and SH-aLRT support for branches are denoted by dots at nodes, where open circles denote 100% UFboot and 100% SH-aLRT support and closed circles denote 100% UFboot and <100% SH-aLRT support, and no dot present on the node indicates <100% for both metrics. Concordance factors are provided next to node dots, with gene concordance (gCF) positioned above site concordance (sCF). Posterior probabilities from the MrBayes 50% majority-rule consensus tree are superimposed to the left of the concordance factors in bold type at nodes where branch support is not maximal (i.e. <1; dashes occur where a branch was non-existent in the MrBayes tree). Short, unsupported branches that effectively form a polytomy in the backbone of the tree are coloured red. Red asterisks at nodes indicate branches that are well supported in our phylogeny but were unsupported in the plastid sequence phylogeny of Duretto et al. (2023). Sections of Philotheca are listed in grey, and are linked to corresponding taxa by dashed lines.
