A widely distributed perennial, mostly occurring in the N hemisphere; leaves entire to deeply toothed, arranged spirally around the stem or often in a basal rosette; flower-heads solitary or in loose clusters, florets usually yellow. Many hawkweeds reproduce from fruits formed without fertilization having occurred, resulting in vast numbers of distinct populations or microspecies, perhaps as many as 20 000. (Genus: Hieracium, c.250 species. Family: Compositae.)
