Fig. 6. Results of topology tests for the backbone polytomy in the Eriostemon group. (a) The 15 possible resolutions of the polytomy (for the four supported clades) that testing was conducted on, ordered by most likely to least likely from left to right, top to bottom (note: the hard polytomy resolution is not depicted). (b) Plot of log likelihoods for each possible topology. The topology matching the most likely tree is denoted by a star, and the hard polytomy topology is denoted by a triangle.

Fig. 5 in Plastid phylogenomics of the Eriostemon group (Rutaceae; Zanthoxyloideae): support for major clades and investigation of a backbone polytomy

Fig. 5. Results of the likelihood-mapping analysis of loci. (a) Plot of phylogenetic informativeness of individual loci, where a higher percentage of fully resolved quartets for a locus indicates greater support for tree-like evolution. Dashed lines on the plot indicate the three cut-off values that were tested for potentially improving phylogenetic resolution of the polytomy (i.e. 50, 60 and 70%). Bars along the x-axis denote the cluster that each locus was placed in during the analysis of tree space; some loci were excluded from the tree-space analysis, owing to incomplete representation of samples. (b) Phylogenetic network (NeighborNet) showing splits of the backbone polytomy; constructed from a concatenated alignment of all loci with>60% of quartets fully resolved. For Crowea, EA, eastern Australia; WA, western Australia.

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.

Fig. 4. Phylogenetic relationships in Clade 1. Maximum-likelihood phylogeny produced from IQ-TREE analysis of the 'supermatrix' alignment of combined full plastome and Sanger sequences. UFboot support for branches is positioned above posterior probabilities from the MrBayes 50% majority-rule consensus tree of the same dataset. Relationships in other clades are identical to those in Fig. 3. Unsupported short branches in the backbone of the Eriostemon group have been manually collapsed to a polytomy. Asterisks denote samples represented only by Sanger sequence data. The MrBayes and IQ-TREE phylogenies differed in the placement of Philotheca angustifolia; this incongruence is shown by red-dashed branches that indicate the topology recovered by MrBayes (posterior probability value relevant to this is in red). Black triangle, Philotheca s.str. (largely equivalent to Philotheca sensu Wilson 1971); black square, Philotheca 'Nigrostipulae' (largely equivalent to Eriostemon section Nigrostipulae sensu Wilson 1970), as discussed in the text.
