Carex muricata subsp. muricata
This perennial herb is confined to dry habitats over limestone, being found on limestone pavements, ledges, grassy slopes and scree; some sites are shaded. Generally lowland, but reaching 340 m in Ribblesdale (Mid-W. Yorks.).
The native Gloucestershire site was lost in 1983 through overgrowth of surrounding vegetation. Plants were re-introduced, but these died out by 1989. A large Shropshire population was discovered in 1999 and an extension to it confirmed in 2000. It may be overlooked or mis-recorded elsewhere.
European Boreo-temperate element; introduced to N. America.
