• Appendix 1 - Outcrossing rates of 20 gyno(monoecious)dioecious species found in 19 studies. Outcrossing values were always estimated for the hermaphroditic (Herm.) individuals and to a less extent for the female ones (half of the studies). In only one of three studies describing gynomonoecious-gynodioecious species were outcrossing rates calculated for the mixed individuals that bear both pistillate and perfect flowers (also referred to as gynomonoecious or intermediate individuals). Mating systems are either gynodioecious (GD), gynomonoecious-gynodioecious (GM-GD) or subdioecious (SD); exclusively hermaphrodite populations are noted as H. The number of families (Nf) and the total number of progenies (Np) analyzed for outcrossing estimations are given.
