Hieracium /haɪ.ərˈæsiəm/,known by the common name hawkweed and classically as hierakion (from ancient Greek ιεράξ, hierax 'hawk'), is a genus of the sunflower (Helianthus) family Asteraceae (or Compositae), and closely related to dandelion (Taraxacum), chicory (Cichorium), prickly lettuce (Lactuca) and sow thistle (Sonchus),which are part of the tribe Cichorieae.
