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.

Rorippa palustris - Marsh Yellow-cress

Marsh Yellow-cress is generally rare and is found in wet habitats such as in the river gravels by the River Fowey at Lostwithiel (SX15E, 1991, R.J.Murphy). It also grows in waterlogged ruts in trackways near Grumbla (SW43A, 1991, C.N.French) and along the shoreline of reservoirs such as Drift (SW42J, 1981, R.J.Murphy), Stithians (SW73C, 1988, S.M.Turk), Siblyback (SX27F, 1989, R.W.Gould) and the Upper Tamar Lake (SS21W, 1992, D.Dupree).
