The African Violet Society of America (AVSA) has the franchise from the International Botanical Congress to register the cultivars of African violets. The AVSA has a registration system for African violet species plants. The most recent registration system was built around the Darbyshire classification system with slight modifications. The AVSA is still considering the classification of Nishii et al. 2015 and may change the registration numbers of the species plants to follow this classification system, although that has not yet been done.
