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.

Lythrum portula subsp. longidentatum

This subspecies of Water-purslane with larger epicalyx segments has been observed growing on a number of moors (e.g. Goss Moor, SW96K and Porkellis Moor, SW63W) and beside reservoirs, including most recently at Drift, (SW42J, 1981, R.J.Murphy). It has also been found on the Isles of Scilly.
