Polypodium is derived from the Greek Polus, many, and podion, small foot, since the rhizome bears numerous roots. Australe comes from the Latin auter, wind of the south, for in Europe, this species grows more particularly in southern France. The common polypody is medicinal plant known since the times of Dioscorides, and its rhizome is used against cough and liver diseases.
