Eriophorum angustifolium
Along with cross-leaved heath and purple moor-grass the valley bog habitat supports bog asphodel ("Narthecium ossifragum"), bog pimpernel ("Anagallis tenella"), common cottongrass ("Eriophorum angustifolium"), lesser skullcap ("Scutellaria minor"), pale butterwort ("Pinguicula lusitanica") and white beak-sedge ("Rhynchospora alba"). Royal fern ("Osmunda regalis") and wavy St. John's-wort ("Hypericum undulatum"), species which are not common within Britain, can also be found in the bogland. A broad-leaved woodland surrounds the valley bog which mainly contains sessile oak ("Quercus petraea"), and willows ("Salix spp.").
