Hylocereus undatus, a hermaphrodite plant with perfect flowers that have both functional carpels and stamens. The term hermaphrodite is used in botany to describe, for example, a perfect flower that has both staminate (male, pollen-producing) and carpellate (female, ovule-producing) parts. The overwhelming majority of flowering plant species ...
Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
In plants, individual flowers are called dichogamous if their function has the two sexes separated in time, although the plant as a whole may have functionally male and functionally female flowers open at any one moment. A flower is protogynous if its function is first female, then male, and protandrous if its function is first male then female.
Andromonoecy is a breeding system of plant species in which male and hermaphrodite flowers are on the same plant. [1] It is a monomorphic sexual system comparable with monoecy, gynomonoecy and trimonoecy. [2] Andromonoecy is frequent among genera with zygomorphic flowers, [3] however it is overall rare and occurs in less than 2% of plant ...
It can be seen that the flower is hermaphrodite and actinomorphic, pentacyclic (i.e., it has 5 floral whorls) and pentamerous (each cycle is composed of five pieces). The floral diagram is a graphic representation of the arrangement of the floral parts and the arrangement of the different whorls, in a cross section of the flower. Each whorl is ...
In monomorphic sexual systems, a combination of hermaphrodite, male, and/or female flowers may be present on the same plant. Monomorphic sexual systems include monoecy, gynomonoecy, andromonoecy, and trimonoecy. In dimorphic sexual systems, individual plants within a species only produce one sort of flower, either hermaphrodite or male, or female.

Gynomonoecy is defined as the presence of both female and hermaphrodite flowers on the same individual of a plant species. [1] It is prevalent in Asteraceae but is poorly understood. [2] It is a monomorphic sexual system comparable with monoecy, andromonoecy and trimonoecy. [3]
