Figure 5: Maximum likelihood ancestral state reconstructions of four representative floral characters.
Figure 5

The pie charts at the centre of the figure indicate the proportional likelihoods for reconstructed ancestral states at 15 key nodes (here we optimized the characters on the maximum clade credibility tree from the C series; for complete results, see Supplementary Data 1 and Supplementary Data 14–23). Grey branches denote missing, inapplicable or polymorphic data. (a) Ovary position (character 102_B). (b) Fusion of perianth (character 204_A). (c) Symmetry of perianth (character 207_B). (d) Number of perianth whorls (character 231_A).
