Clearly, understanding the evolutionary dynamics of the sex ratio in gynodioecious plants requires that the fitness of the two sexes be compared from both the cytoplasmic and nuclear perspectives.

The remaining sexual systems are found exclusively among the dicots: Gynomonoecious species include 7% of the flora and are in Abrotanella, Cuminia, Chenopodium, Erigeron, and Lactoris; the one gynodioecious species is in Rhaphithamnus; polygamous taxa are scarce and included in Empetrum and Parietaria, as are andromonoecious taxa included in Cyperaceae and Asteraceae.
