Diversification history of EFN location on leaves in Senna. Parsimony reconstruction of ancestral states of character B (location of EFNs on leaves; 23 steps, RI = 0·64, CI = 0·22) on the ML tree by Marazzi and Sanderson (2010). Roman numbers indicate clades I–VII (Marazzi et al., 2006a). The graphic in the upper left corner summarizes results by illustrating the minimum number of transitions inferred among states. Results for each state at each node can be found in Supplementary Data Appendix S3 and summarized for selected nodes in Supplementary Data Table S1.
