Range & Status
Syn. C. erichsoni du Buysson. Restricted to a few coastal sites in south-western Britain.
Regional Distribution
Known from the Lizard Peninsula since 1917. Found on seacliff rock-heath at Lizard Point by K.N.A. Alexander in 1989 and by Ian McClenaghan in 2002; also at Old Lizard Head by Paul Gainey in 2007.
Habitat & Ecology
Thought to develop at the roots of plants in unimproved swards on dry freely-draining
soils. The Cornwall sites are sea-cliff grasslands.
Threats
Abandonment of grazing and the conversion of its coastal pasture sites to more productive agricultural swards.
Conservation
Lizard Point is owned by The National Trust.
