[Centaurea jacea does not occur in NL; anecdotal report of this species from NL are often based on misidentifications of Centaurea nigra, which is very common in Nfld. Centaurea jacea differs by having light to medium brown involucral bracts (phyllaries) that are more shallowly fringed than those of Centaurea nigra, which has dark brown to blackish involucral bracts with deeply divided (pectinate) margins. Also, Centaurea jacea has achenes (cypselae) that lack pappus bristles, while cypselae of Centaurea nigra terminate in a crown of short blackish pappus bristles, to 1 mm long.]
