Mercurialis perennis
Ground-layer plants are dominated by bilberry ("Vaccinium myrtillus"), bramble ("Rubus fruticosus"), common bracken ("Pteridium aquilinum"), dog's mercury ("Mercurialis perennis"), false brome ("Brachypodium sylvaticum"), great wood-rush ("Luzula sylvatica"). Scarce and locally uncommon plants that are found in the gorge are narrow-leaved bittercress ("Cardamine impatiens"), stinking hellebore ("Helleborus foetidus"), wood barley ("Hordelymus europaeus") and wood fescue ("Festuca altissima").
