What is "androdioecy"

n. A reproductive system found in species composed of a male population and a distinct hermaphrodite population.

Androdioecy is a reproductive system characterized by the coexistence of males and hermaphrodites. Androdioecy is rare in comparison to the other major reproductive systems dioecy and hermaphroditism. In animals, androdioecy has been considered an important stepping stone in the transition from dioecy to hermaphroditism, and vice versa.
