System

The position and value of the taxon is in discussion. Frequently Cystopteris dickieana is a subspecies of the Fragile Blasenfarns than Cystopteris fragilis subsp. dickieana out. It might be a mutant of Cystopteris fragilis without a separate area and without an independent ecology here, however.
