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
Formerly widespread along the south coast of Britain, but with very few recent records.
Known from one old record near Looe (1906).
Habitat & Ecology
Favours dry freely-draining mainly sandy soils, and may be a species of wind-blown shelly sand vegetation; probably feeds mainly on seeds.
Development of sand dune systems and coastal cliff lands for recreation; coarsening of vegetation through lack of grazing and/or trampling, with consequent loss of open sandy areas; coastal protection works.
Much of the more sensitive coastline is now protected by SSSI designations.
