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.

Ophioglossum vulgatum - Adder's-tongue

In Cornwall it is a rare fern of wet meadows, moorland and coastal sand dune slacks. It has been lost from most of its former localities, but is still present on Phillack Towans (SW53U) and two new sites have been found. These are on Lelant Towans (SW53P 1998 C.N.French), and at Lady Down on Bodmin Moor (SX17D 1998 D. Glaves).
