Pilosella lactucella (synonym Hieracium lactucella,[1] also called European hawkweed) is a species of perennial plant from the family Asteraceae, found in Europe, New York (United States) and Nova Scotia (Canada).[2] It is 9–20 centimetres (3.5–7.9 in) in height, with stems from 1–2 millimetres (0.039–0.079 in) wide. The leaves are spatula shaped and 5–8 centimetres (2.0–3.1 in) wide. The flowers bloom from May to July, the heads of which are 2–5 centimetres (0.79–1.97 in) tall. It was once described by Carl Linnaeus as Hieracium auricula and Pilosella auricula, but was recategorized by A. E. Roland and M. Zinck in 1998.[3]
