Asplenium marinum (Sea Spleenwort)
An evergreen perennial fern, predominantly found in cool, moist crevices and fissures in maritime cliffs, and often within range of sea-spray. It occasionally grows on walls in coastal areas, but, because of its requirement for a frost-free environment, it is only exceptionally found on rocks inland. Lowland.
Most of the British sites lacking a post-1970 record were lost before 1930, and the distribution of this species is currently stable.
Suboceanic Southern-temperate element.
