Fig. 2.

Phylogenetic relationships in the Solanaceae species (356 species). Self-incompatibility (SI) and self-compatibility (SC) are depicted by purple and turquoise tips, respectively. Probability distribution of transitions (and 95 % credibility intervals) between characters. (A) Estimates of transition (q), extinction (μ) and speciation (λ) are given for SI species (I subscript) and SC species (C subscript). (B) The net diversification rate is the difference between speciation and extinction rates. (C) Summary of estimated parameters (taken from Goldberg et al., 2010, with permission).
