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 crispus - Curled Pondweed



This easily recognisable pondweed is largely confined to East Cornwall, especially the upper reaches of the Tamar (SS21) and the Bude Canal (SS20B), but it also occurs in the River Amble and its tributaries (SW97X), to the north of the Camel estuary. Elsewhere it is found in relatively few lakes and ponds and is absent from the Isles of Scilly.
