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.

Juncus pygmaeus - Pigmy Rush

Pygmy Rush, a Red Data Book species, is restricted in Britain to the Lizard Peninsula. Growing in winter-flooded tracks over serpentine and gabbro, it was once locally abundant and between 1956 and 1984, 22 sites were noted. By 1994 only three of these could be found and the rush was considered as highly endangered. Recently, however, plants have been seen at two of the old sites and an entirely new population has been discovered. It is clear that populations and sites vary from year to year, but it is also certain that population numbers are lower than they used to be, and that habitat conditions along some of the tracks have changed. There are two old records from an outlying site at Loe Pool. The most recent being lodged in the herbarium of Liverpool Museum (SW62M, 1951, J.E.Jousley).
