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.

Other authors considered enantiostyly as enigmatic (Thorp and Estes 1975).
Those flowers borne in the same node show somatic inverse enantiostyly.

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.
Enantiostyly is a floral polymorphism in which flowers possess either left- or right-bending styles (Fig.
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).
In the otherwise monosymmetric Exacum (Gentianaceae) enantiostyly is present (Lloyd & Webb, 1992).
