Fig. 6 in Using RADseq to resolve species boundaries in a morphologically complex group of yellow-flowered shrubs (Geleznowia, Rutaceae)

Fig. 6. Concatenation maximum-likelihood phylogenetic tree of Geleznowia and two outgroup taxa. Monophyletic groups are collapsed for clarity and labelled with population numbers. Coloured numbers correspond to genomic groups in the PCA and are coloured by initial morphological identification, whereas colours of clades match colours in the Structure figure. Support values are Shimodaira–Hasegawa-like approximate likelihood-ratio test values and ultrafast bootstrap values, in that order. All branches have full support (100/100) except where shown. The scale bar indicates the average number of substitutions per site. Branches are cut in the main figure for clarity, but full branch lengths are provided at the top left.
