An evergreen perennial fern of sheltered, humid, moist habitats, including rocky woodlands, stream and hedge banks, grikes in limestone pavement, and on brickwork and walls, where it often grows in a stunted form. It avoids the most acidic substrates. 0-700 m (Great Dun Fell, Westmorland).
The range of this species appears to be unchanged since the 1962 Atlas, where it was mapped as `all records`, although it is now better recorded. Although treated here as Phyllitis scolopendrium, it is clear from molecular evidence that the genus Phyllitis should be subsumed into Asplenium.
European Temperate element; also in E. Asia and N. America.
