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.

Potamogeton natans - Broad-leaved Pondweed

Broad-leaved Pondweed is found in a variety of still, freshwater habitats, in lakes such as Pendarves (SW63N, 1977, S.M.Turk), quarry pools as at Gaverigan (SW95J, 1995, R.J.Murphy), ponds as on Breney Common (SX06K, 1996, M.Atkinson) and in a pond near Tamar Lake (SS21V, 1995, M.Atkinson). It doesn't seem to occur in streams or rivers in Cornwall and it is not as frequent here as elsewhere in Britain. It has been recorded on Scilly.
