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.

Cirsium palustre - Marsh Thistle

Marsh Thistle is normally found in damp habitats on poorly draining soils. Occasionally, isolated plants appear in drier areas, such as high up on the embankment of the Zelah bypass (SW85A) and on some steep slopes on the Penwith moors. On the Isles of Scilly it is a local plant on St. Mary's.
