Mirror-image flowers (enantiostyly) are a sexual polymorphism in which the style is deflected away from the floral axis either to the left (left-styled flower) or the right (right-styled flower) (Jesson & Barrett, 2002; Gao et al., 2006).
Enantiostyly: solving the puzzle of mirror-image flowers.
The style was positioned to the right on one flower and to the left on another, demonstrating enantiostyly
Moreover, differential fertility and enantiostyly may diminish the effects of self-compatibility by partially reducing the contribution of geitonogamy to selfing.

The flowers also show enantiostyly; the stylar deflection results in left or right-handed flowers and pollen deposition is produced to one side of the bee's abdomen when it vibrates the stamens.

1) involving the relative positions of male and female sex organs are present in the family: tristyly, a genetic polymorphism found in Eichhornia and Pontederia; enantiostyly, a floral polymorphism that predominates among species of Heteranthera and Monochoria; and floral monomorphism, found in all four major genera.
The most well known cases are enantiostyly or enantiomorphy.
Enantiostyly and enantiomorphy express the presence of two mirror-image like morphs (either on the same individual or on different individuals).
