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.

Osmunda regalis - Royal Fern

This majestic fern grows in a wide variety of situations including sea caves, zawns, cliff faces and undercliffs, mine shafts, bogs and deep within valley bottom marshes dominated by Salix scrub. A fern of wet, acidic habitats, it is also tolerant of exposure to salt and can be very luxuriant in flush sites on cliffs. Fine specimens can also be seen within dank woodland marshes as in the Red River valley north of Camborne (SW64A) and in the mid-Cornwall moors as on Breney Common (SX06K). It also occurs on the Isles of Scilly.
