Erica tetralix
Between Boscaswell Cliffs and Clodgy Point the site is characterised by a number of wet flushes and an extensive area of mire at Boswednack. The flushes are dominated by purple moor-grass "Molinia caerulea" and typical species occurring here include cross-leaved heath "Erica tetralix", tormentil "Potentilla erecta", sharp-flowered rush "Juncus acutiflorus" and royal fern "Osmunda regalis". Other species of note associated with the wet flushes include bog asphodel "Narthecium ossifragum", the cottongrass "Eriophorum angustifolium" and pale butterwort "Pinguicula lusitanica". The nationally scarce plants Cornish moneywort "Sibthorpia europaea" and yellow bartsia "Parentucellia viscosa" are found at Boswednack.
