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. European Temperate plant; also in North America. Mainly found in coastal counties of western and southern Britain and northern and western Ireland.
In Cornwall it is found scattered in heathy areas; the Lizard heaths are a stronghold. In the Isles of Scilly the plant is only found on St. Martin' s (SV91) and St. Agnes (SV80). There is an earlier record from Tresco (SV81).
Habitat & Ecology
A tiny, easily overlooked, plant of compacted heathland tracks, forestry tracks, gravel carparks and quarry floors, anywhere where there is little competition from other vegetation. Occurs on some mine sites, particularly where mineral processing took place.
Surfacing of trackways and loss of heathland.
Some of the sites are in SSSI.
