Protogynous: (of dichogamous plants) having female parts of flowers developed before male parts, e.g. having flowers that function first as female and then change to male or producing pollen after the stigmas of the same plant are receptive. [6] Subandroecious: having mostly male flowers, with a few female or bisexual flowers. [24]
Autoicous – produces male and female sex organs on the same plant but on separate inflorescences. Bract – leaf is present below the flower. Cladautoicous – male and female inflorescences are on separate branches of the same plant. Dioicous – having two forms of gametophyte, one form bearing antheridia and one form bearing archegonia.
In some species of plants, the flowers are imperfect or unisexual: having only either male (stamen) or female (carpel) parts. If unisexual male and female flowers appear on the same plant, the species is called monoecious. [23] However, if an individual plant is either female or male, the species is called dioecious.
Floral sexuality is related to the presence or absence of the reproductive whorls: androecium and gynoecium. Flowers that have both whorls (i.e., will produce both male and female gametes) are said to be perfect, bisexual, monoclinous or, more frequently, hermaphrodites, as is the case with potato flowers (Solanum tuberosum, Solanaceae
