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.

Hypericum hirsutum - Hairy St John's-wort

Hairy St. John’s-wort is extremely rare in Cornwall. It was reported from a stream bank between Mawgan Porth and Trevose Head in 1955 (SW87, M.S.Johnson) and two clumps were discovered growing in open scrub on top of an embankment by a disused railway on the south side of Bagbury Farm, near Bude, in 1994 (SS20C, T.J.Dingle).
