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.

Bidens cernua - Nodding Bur-marigold

Nodding Bur-marigold was last recorded in Cornwall in 1983 by Carminowe Creek, off Loe Pool (SW62M, R.J.Murphy). It had not been seen at Loe Pool for over 80 years before this. This record was confirmed by A.J.Byfield.
