  abstract = {{A}ndrodioecy is a sexual system in which males co-occur with hermaphrodites, which have both male and female function. {S}table androdioecy is rare in nature, and theory suggests that it requires that males sire more than twice as many offspring as hermaphrodites. {I}n several members of the olive family ({O}leaceae), androdioecy occurs with higher frequencies of males than predicted by theory. {I}n {P}hillyrea angustifolia {L}., we found that high male frequencies can be maintained in natural populations because hermaphrodites belong exclusively to one of two self-incompatibility groups, and thus, each can fertilize only half of all pollen recipients. {I}n contrast, males can pollinate all hermaphrodites. {T}hus, in this species, the reproductive disadvantage that males face due to the loss of female function is offset by the fact that all males are fully compatible with all pollen recipients.},
