CO-SEXUAL FORMS. “First, dioecy in flowering plants seems often to have evolved from either hermaphroditism or monoecy, or, using the combined term, from co-sexuality. It follows directly that, during the evolution of dioecy, either females or males must first have arisen, and become established in the population (creating a situation with both co-sexuals and unisexuals, either gynodioecy or androdioecy), and then mutations must have spread among the co-sexuals, making them become the complementary unisexual form.”
