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.

Carex vesicaria - Bladder-sedge

Bladder-sedge is extremely rare in Cornwall and some of the old records may be suspect. At present it is restricted to the Upper Tamar by the old canal near Crowford Bridge (SX29Z, 1986, R.W.David), at North Tamarton (SX39D, 1986, R.W.David), Westcott Farm (SX39E, 1998, M.Atkinson) and at the Tamar Lakes (SS21V, 1985, W.H.Tucker).
