The corolla-lobes exhibit a little variation among themselves with respect to their shape and size, thereby imparting a slight zygomorphy to the floral symmetry.
Floral symmetry is an important trait both in taxonomy and in pollination systems, and normally zygomorphy is thought to be more specialized in pollination adaptations, since it restricts pollinator behaviors and can therefore increase pollination efficiency (Sargent, 2004; Gong & Huang, 2009).
Zygomorphy (or when a flower can only be divided down the middle to make two equal mirror images) is thought to restrict the types of pollinators that can take nectar and pollen from the flower.
