Describing a plant species where some individual plants have both male and female flowers while others have only male flowers.
From Greek 'andros' (male) and 'dioikos' (two households). The term describes a specific reproductive strategy between pure hermaphroditism and complete dioecy.
Some plants like ash trees use androdioecism as a reproductive gamble—some trees produce both sexes of flowers while others go all-in on being male, creating a complex mating system.
