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;^[1] receptaculo nudo, styli ramis longis, pappo praesente, achaeniis 10-costatis.^[2]

Nomen huius generis a vocabulo Graeco ἱέραξ (accipiter) originem ducit propter opinionem Dioscoridis accipitres his plantis ad curandos morbos oculorum uti.^[3] Pilosella, olim ut subgenus Hieracii habita, nunc tamquam genus tractatur; a Hieracio stolonibus praesentibus differt.^[2]

Distributio

Hieracia in Europa, Asia, America septentrionali et America meridionali crescunt.^[2] Hoc genus species permultas continet, circa 10 000^[4] vel etiam plus^[5], quarum pars species asexuales (agamospecies seu microspecies) sunt. In Insulis Britannicis 412 species Hieraciorum crescunt.^[4] Botanici qui Hieracia investigantur, hieraciologi dicuntur; inter hieraciologos Alexander Boreau, Casimirus Arvet-Touvet, Carolus Hermannus Zahn, et Albertus Üksip notantur.
