Cystopteris alpina (Lamarck) Desvaux

Cystopteris alpina is a fern in the family Cystopteridaceae. It is closely related to C. fragilis and has been treated as conspecific with that species by many authors.^[1] It is known to hybridise with C. fragilis in Scandinavia^[1] and intermediate plants possibly of hybrid origin are known from North Wales.^[2]

Distribution

C. alpina is a montane species occurring through most of Europe with populations extending into Russia and West-Asian mountain regions.^[1] It is widely distributed through Northern Scandinavia, the Alps and the Pyrenees. In Britain it is thought to be extinct having only been known from one locality in Upper Teesdale where it was last recorded in 1911.^[2]

Ecology

C. alpina is restricted to limestone in damp locations mainly in upland areas.^[1]
