Plant Reproductive Terminology
Bisexual
Each flower of each individual has both male and female structures, i.e. it combines both sexes in one structure, having both stamens and carpels. Other terms used for this condition are androgynous, hermaphroditic, monoclinous, synoecious, and perfect
Dichogamous
having sexes developing at different times; producing pollen when the stigmas are not receptive, either protandrous or protogynous. This promotes out crossing by limiting self-pollination. Some dichogamous plants have bisexual flowers, others have uni-sexual flowers.
Monoecious
In the commoner narrow sense of the term, it refers to plants with uni-sexual flowers which occur on the same individual. In the broad sense of the term, it also includes plants with bisexual flowers. Individuals bearing separate flowers of both sexes at the same time are called simultaneously or synchronously monoecious.[citation needed] Individuals that bear flowers of one sex at one time are called consecutively monoecious.
Gynomonoecious
Having both bisexual and female flowers on the same plant.
Andromonoecious
Having both bisexual and male flowers on the same plant.
Unisexual
Having either functionally male or functionally female flowers. This condition is also called diclinous, incomplete or imperfect.
Dioecious
Having either only male or only female flowers. No individual plant of the population produces both pollen and ovules.
Protogynous
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.
Gynodioecious
Having hermaphrodite flowers and female flowers on separate plants.
Androdioecious
Having male flowers on some plants, bisexual ones on others
Protandrous
Having male parts of flowers developed before female parts, e.g. having flowers that function first as male and then change to female or producing pollen before the stigmas of the same plant are receptive
Androgynomonoecious
Having male, female, and bisexual flowers on the same plant, also called trimonoecious
Polygamous
Having male, female, and bisexual flowers on the same plant. Also called polygamomonoecious, trimonoecious, and trioecious
Subgynoecious
Having mostly female flowers, with a few male or bisexual flowers.
Subandroecious
Having mostly male flowers, with a few female or bisexual flowers.
Gynoecious
Having only female flowers (the female of a dioecious population); producing seed but not pollen.
Androecious
Having only male flowers (the male of a dioecious population); producing pollen but no seed.
Subdioecious
Having some individuals in otherwise dioecious populations with flowers that are not clearly male or female. The population produces normally male or female plants with unisexual flowers, but some plants may have bisexual flowers, some both male and female flowers, and others some combination thereof, such as female and bisexual flowers. The condition is thought to represent a transition between bisexuality and dioecy.
Imperfect
Having some parts that are normally present not developed, e.g. lacking stamens.
Polygamodioecious
Mostly dioecious, but with either a few flowers of the opposite sex or a few bisexual flowers on the same plant.
