Pilosella Hill. Mouse-ear Hawkweed.
A genus of 20-80 species (depending on species concepts applied to the many apomictic and hybrid-derived entities), herbs, of Eurasia and n. Africa. Sometimes included in Hieracium, the separation of Pilosella as a genus is increasingly supported by molecular, morphological, and biological evidence, and has become the dominant approach in Europe (Bräutigam & Greuter 2007) and worldwide (Funk et al. 2009; Kilian, Gemeinholzer, & Lack 2009).
