Main flower color:
Most widespread in south Wales and south England; much less common further north
Up to 60 cm
Dry grassland, often on calcareous soils
Five pink petals, slightly pointed at the tip, crossed by dark purple veins. Petal bases are fringed with white hairs. The sepals, partially spreading when mature, are light green with darker lengthwise bands and a whitish margin. Sepals terminate in a bristle, often reddish at the apex. Flowers are attached by relatively long stalks, up to 6 cm
Divided almost to the base into five or seven lobes, themselves partially divided, into linear segments. Sparsely covered by relatively thick white, appressed hairs, as are the stems
