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.

Cladium mariscus - Great Fen-sedge

Great Fen-sedge is extremely rare and restricted to the Lizard in Cornwall. One of the better known sites is in the marsh at the side of Kynance Stream, near Kynance Gate (SW61W). However, the largest population is to be found at Maindale, near St. Keverne (SW72V).
