The genus Anthona was first described by the Swedish botanist Carl Linnaeus in 1753, and has since been revised and expanded by numerous taxonomists. As of 2021, the genus is estimated to contain around 150 species, with the majority of species occurring in Africa. The genus is further divided into several subgenera, based on morphological and molecular characteristics.

In conclusion, Anthona is a diverse and interesting genus of flowering plants, with a wide range of uses in traditional medicine and horticulture. Further research is needed to fully understand the taxonomic relationships within the genus, as well as the potential medicinal and ecological significance of its species.
