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.

Achillea maritima - Cottonweed

This Red Data Book species is probably now extinct in Cornwall and the Isles of Scilly. It was last seen in 1936 on St. Martins (SV91H). The last mainland record was from Par Sands in 1933 (SX05R, L.T. Medlin).
