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.

Asplenium ceterach - Rustyback Fern

Rustyback Fern is locally frequent in parts of East Cornwall but very rare in the west. The lack of suitable habitat in West Cornwall may explain this distribution. It becomes more frequent towards the Tamar but is also common around the Camel (SW97) and is most easily seen on bridges as at Helland Bridge, (SX07Q) and Moreton Mill Bridge (SS20Z). In 1996, C.N. Page refound it growing by the old Methodist chapel in Ponsanooth (SW73N) which was the original site found by F.H. Davey's father. Rustyback Fern was reported in 1956 from St. Martin's on the Isles of Scilly (Lousley, 1971).
