Hieracium (planta)
Hieracium genus plantarum angiospermarum est, e familia Compositarum et tribu Cichoriearum.

Descriptio 
Hieracia herbae perennes sunt, caudice ramoso sed stolonibus nullis; indumento duplici (pilis tum glanduliferis tum stellato-floccosis); corolla flava, rarius aurantiaca rubrave; receptaculo nudo, styli ramis longis, pappo praesente, achaeniis 10-costatis.

Nomen huius generis a vocabulo Graeco ἱέραξ (accipiter) originem ducit propter opinionem Dioscoridis accipitres his plantis ad curandos morbos oculorum uti. Pilosella, olim ut subgenus Hieracii habita, nunc tamquam genus tractatur; a Hieracio stolonibus praesentibus differt.

Distributio 
Hieracia in Europa, Asia, America septentrionali et America meridionali crescunt. Hoc genus species permultas continet, circa 10 000 vel etiam plus, quarum pars species asexuales (agamospecies seu microspecies) sunt. In Insulis Britannicis 412 species Hieraciorum crescunt. Botanici qui Hieracia investigantur, hieraciologi dicuntur; inter hieraciologos Alexander Boreau, Casimirus Arvet-Touvet, et Carolus Hermannus Zahn notantur.
