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.

Amaranthus blitum - Guernsey Pigweed

Guernsey Pigweed was last seen in 1926 at Par Harbour (SX05R, L.T.Medlin) where it was of casual occurrence and probably introduced with imported produce or ballast. Prior to that it was seen at Eastern Green, Penzance (SW43Q, 1892, W.A.Glasson) and Trevol, near Torpoint (SX45H, 1871, T.R.A.Briggs).
