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).

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.
