The evolution of dioecy in plants has traditionally been explained as a result of selction for outcrossing (Baker 1959; Carlquist 1966, 1974; Lewis 1942; Lloyd 1972, 1975; Mather 1940; Maynard Smith 1978; Ross 1970; 1978; Ross and Shaw 1971; Ross and Weir 1976; Stebbins 1951). Population genetical models, notably those of Charlesworth and Charlesworth (1978, 1979) have indicated that inbreeding de pression is usually necessary for the evolution of dioecy from hermaphroditism.
