Common polypody


This attractive woodland fern takes both its scientific and common names from the creeping, hairy rhizomes (underground horizontal stems) that grow in a spreading mat, near or at the soil surface. Fronds that are deeply divided into 10 to 18 pairs of leaflets appear at intervals along the rhizomes. On the bottom side of the fronds reproductive spores are produced in conspicuous oval spore cases.

Habitat: Wooded hillsides and stream banks, in rocky nooks and crannies, and at the base of trees in deep to dappled shade. Mid-to upper elevation zones.

Scientific name: Polypodium australe Fee
sin. Polypodium vulgare var. serrayum Willd.
Italian common name: Polypodio meridionale
English common name: Common polypody
