Fig. 8 in Pollen characters and DNA sequence data converge on a monophyletic genus Iresine (Amaranthaceae, Caryophyllales) and help to elucidate its species diversity

Fig. 8. Evolution of pollen morphology using the maximum clade credibility tree of the plastid analysis with a reduced sampling. Pie charts depict the ancestral states reconstructed for pollen form (character 1), aperture number (character 2), aperture diameter (character 3), shape and diameter of mesoporia (characters 4, 5), and pollen size (character 6). For character and state definitions see Appendix 2.
