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.

Berteroa incana - Hoary Alison

Hoary Alison was a casual alien and has not been recorded since 1935. It is known to have been spread by the railways and indeed one of the records came from near the railway station at Launceston (SX38H, 1902, W.Wise). It could also have arrived by sea as suggested by a record from Par (SX05R, 1901, A.O.Hume).
