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.

Pilularia globulifera - Pillwort

Pillwort, ranked in Britain as Nationally Scarce, is decreasing rapidly throughout its European range. In Cornwall it has not been seen for many years at most of its former sites outside the Lizard and the mid-Cornwall moors. It is found at the edge of (or submerged in) standing water, usually on a muddy substrate. Its occurrence in a newly created roadside ditch on the edge of Goss Moor (SW96F, 1997, I.J.Bennallick) confirms its ability to be a colonist where suitable conditions arise. On the Lizard it is regularly seen at Hayle Kimbro Pool (SW61Y) and at Croft Pascoe Pool (SW71J) and was refound after a gap of 15 years in one of the pools north west of Traboe Cross (SW72F, 1998, I.J.Bennallick). It is still plentiful on Breney Common (SX06K).
