Trimonoecy
Trimonoecy, also called polygamomonoecy, is when male, female, and hermaphrodite flowers are on the same plant.[1] Trimonoecy is rare.[2]
It is a monomorphic sexual system along with monoecy, gynomonoecy, and andromonoecy. It is hypothesized that trimonoecy originated from gynomonoecy.[3]
Occurrence
[edit]Trimonoecy occurs in plant families like Anacardiaceae, Apiaceae, Araliaceae, Chenopodiaceae, Fabaceae, Orchidaceae, Palmae, and more.[4] It is rare in the family Commelinaceae.[5]: 309
Trimonoecious species include:
- Cocos nucifera[6]
- Sanguisorba minor[7]
- Thymelaea hirsuta[8]
- There is evidence Phyllanthus acidus is trimonoecious.[2]
