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; an Submediterranean-Sub Atlantic species that extends north into the Channel Islands (Jersey) and western Britain, where it was recently re-found in Radnorshire but is otherwise restricted to The Lizard in Cornwall.
In Cornwall it has been recorded in 19 1km squares, all on west side of The Lizard (SW61), but only six 1km squares since 1999. There are two historic inland outliers, at Chypons (SW62) and Goonhilly Downs (SW71).
Habitat & Ecology
A maritime grassland plant, it is found both on the serpentine and on The Lizard schists, growing on cliff slopes and edges. On the exposed west coast of The Lizard it can extend inland up the valleys, growing on grazed grassy banks that overlie shallow stony soils.
Threatened by a lack of grazing, scrub invasion and adverse human activity.
Much of the southern part of the Lizard Peninsula is SSSI and managed by the National Trust and Natural England.
