Trimonoecy
Trimonoecy, also called polygamomonoecy or androgynomonoecy, is a sexual system in plants in which a single individual produces male, female, and hermaphroditic flowers simultaneously. Trimonoecy is rare, occurring in 0.025% of angiosperm species.
It is a monomorphic sexual system along with monoecy, gynomonoecy, and andromonoecy. It is hypothesized that trimonoecy originated from gynomonoecy.
