A corrected lectotypification of the name Artemisia umbrosa (= A. vulgaris var. umbrosa, Asteraceae) is discussed. It is demonstrated that Besser (1832) in fact cited in the protologue four concrete specimens that should be thus treated as syntypes. Following Art. 9.3 and 9.12 of the International Code of Nomenclature for algae, fungi, and plants (Shenzhen Code, Turland et al., 2018), the earlier lectotype designation by Korobkov (2014) is superseded, and one of the syntypes is designated here as the lectotype, the specimen KW001000452 from the Besser historical herbarium at the National Herbarium of Ukraine (KW).

Keywords: Artemisia, Asteraceae, alien species, nomenclature, typification, lectotype
