Phyllitis scolopendrium
Ecology
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).
Status
Trends
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.
World Distribution
European Temperate element; also in E. Asia and N. America.
