Flora of Cornwall (1999)

The descriptive text, below the map, is from the Flora of Cornwall (1999), which was a Tetrad Atlas (the maps had 2km square dots or Tetrads). The map on this web page depicts the plant's distribution at the 1km square scale and shows the records made pre-2000 which were used in the 1999 Flora and those made since.

Cystopteris fragilis - Brittle Bladder-fern



Brittle Bladder-fern has always been extremely rare in Cornwall. The only place it can be found with a degree of certainty is along a lane past Penjerrick, towards Mawnan Smith, where it has long been naturalised (SW73Q).
