Taxonomic Comments
According to Flora of North America (2006), "recent studies have shown that the American plants are identical with plants introduced to the whole of Europe. C. stoebe ssp. micranthos, a tetraploid perennial, is clearly distinct from the diploid, biennial plants native to central Europe known as C. stoebe ssp. stoebe, C. rhenana Boreau, or C. maculosa Lamarck. In most American literature the name Centaurea maculosa Lamarck has been misapplied to C. stoebe ssp. micranthos." Thus C. stoebe ssp. micranthos, the only C. stoebe material believed to be established in North America, is synonymous with Kartesz's (1999) Centaurea biebersteinii.
