Hieracium reitzianum Cabrera ex Urtubey, a new species of Asteraceae from southeastern Brazil, is described and illustrated. This species is placed within Hieracium L. sect. Hypochaeridiformia (Arv.-Touv. ex Peter) Zahn (Hieracium subg. Chionoracium Sch. Bip.) by the presence of ciliate corolla lobes. It is most readily distinguished from other species of the section by having broadly obovate to suborbicular leaves with rounded to obtuse apices.
