Common butterwort  (Pinguicula vulgaris)

This species is fairly common throughout much of Britain, with the exception of central and southern England where it becomes rare and is even absent from several counties (2). In these areas, the species has declined by a worrying 50% since 1930, but many of its sites were lost before the nineteenth century (3).

Found in nutrient-poor damp habitats, including bogs, fens, wet heaths and in rock crevices (2) (3).
