Subshrubs, shrubs, perennial herbs, vines or small trees, monoecious, dioecious, or gynodioecious. Leaves alternate to rarely opposite, rosulate, clustered at the branch apices to clustered in the axils of the old leaves; petiolate, sessile to sheathing at the base; blades entire, lyrate, pinnatisect to pinnately compound, unarmed to spiny, pinnately, palmately to three-veined, rarely parallel-veined, glabrous to pubescent.
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.
Shrubs branched, gynodioecious, short branches modified in thorns.
A further advantage of studying inbreeding depression in gynodioecious species is that this factor may play a key role in the dynamics and maintenance of this sexual polymorphism.
Trees or shrubs monoecious or gynodioecious. Leaves alternate; petiolate; blades obovate, cuneate, entire, glabrescent to tomentose beneath.
Gynodioecious species are those in which individuals can be classified as being either hermaphroditic or functionally female.

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.
