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.

Gastridium ventricosum - Nit-grass

Nit-grass is a Red Data Book species which in Cornwall is now restricted to one wall in Trelissick Gardens (SW83J) and at times in the flower bed at the wall base. Recently it has been recorded as a casual at Lower Downgate, Callington (SX37R, 1997, M. Atkinson).
