Andromonoecy in the context of Monoecious (botany)

Monoecy (/məˈniːsi/; adj. monoecious /məˈniːʃəs/) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system comparable with gynomonoecy, andromonoecy and trimonoecy, and contrasted with dioecy where individual plants produce cones or flowers of only one sex, and with bisexual or hermaphroditic plants in which male and female gametes are produced in the same flower.

Monoecy often co-occurs with anemophily, because it prevents self-pollination of individual flowers and reduces the probability of self-pollination between male and female flowers on the same plant.

Gynomonoecy is defined as the presence of both female and hermaphrodite flowers on the same individual of a plant species. It is prevalent in Asteraceae but is poorly understood.

It is a monomorphic sexual system comparable with monoecy, andromonoecy and trimonoecy.

Trimonoecy, also called polygamomonoecy, is when male, female, and hermaphrodite flowers are on the same plant. Trimonoecy is rare.

It is a monomorphic sexual system along with monoecy, gynomonoecy, and andromonoecy. It is hypothesized that trimonoecy originated from gynomonoecy.
