Figure 1

Tree structure is derived from taxonomy, where each tip represents all species in a single genus. Diploid chromosome number is indicated by the height of the innermost ring; all other rings indicate the presence or absence of the trait named at the base of the ring. The ‘Other’ ring includes the states: apomictic, gynomonoecy, andromonoecy, polygamodioecy, and polygamomonoecy. The sexual trait data displayed in the rings is based on 11,038 plant entries.
