Fig. 8 in Morphological trait evolution in Solanum (Solanaceae): Evolutionary lability of key taxonomic characters
Fig. 8. Evolution of the most conserved morphological traits in Solanum with <10 transitions based on species-level analysis using stochastic character mapping. A, Pseudostipules; B, Enlarged anther connectives; C, Anther modifications; D, Pedicel insertion. Results from the best model are shown for each character (see Table 1 and suppl. Table S4 for details) based on 200 simulations. The topology used for mapping was derived from a supermatrix phylogeny with nine loci (two nuclear and seven plastid loci; Gagnon & al., 2022) with 725 species sampled and coded for each trait (58% of all species). All minor clades are labelled; tips reflect the crown nodes of each minor clade. Piecharts indicate likelihood of modelled ancestral states along the nodes, and frequency bars (tips) reflect proportion of species sampled within each clade with each state.
