The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
Native. Oceanic Southern-temperate grass. Scattered around the coast of southern Britain from the Wash to South Wales, with a few sites in northern England and one inland outlier in Cheshire.
It occurs at Millbrook (SX45) and at several sites in the River Fal catchment (SW83 and SW84). It probably still occurs near Egloshayle (SX07).
