Acrodon bellidiflorus is one of the tooth-leaved mesemb genera. Acros is a Greek word meaning sharp, extremity or tip. Odus, also Greek, means tooth. So the Acrodon genus gets the honour of being named for the toothed leaf feature, which it shares with Faucaria, Carruanthus, Hammeria and five more genera.
The genus comprises only four species, all endemic to the Western Cape south coast. Acrodon bellidiflorus is the only member of the genus found in the Little Karoo across the mountains to the north as well (Smith, et al, 1998; Vlok and Schutte-Vlok, 2010).
