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.

Fig. 10 in Pollen characters and DNA sequence data converge on a monophyletic genus Iresine (Amaranthaceae, Caryophyllales) and help to elucidate its species diversity

Fig. 10. Evolution of pollen morphology, continued from Fig. 9. Pie charts depict the ancestral states reconstructed for the ektexinous bodies on the aperture membrane including their number (character 13), density (character 14) and shape (character 15). Character 16 defines the reproductive system. Consistently hermaphroditic flowers (state 0) are ancestral and widespread in Amaranthaceae, while the Iresinoids are mostly dioecious (state 1) or sometimes gynodioecious (bisexual and pistillate flowers appear on the same plant; state 2).
