--><p><i>Amberboa</i> has often been included within <i>Centaurea</i>, from which it differs by cypselae each with a denticulate apex and a conspicuous rim around the basal scar. The chromosome base number x = 16 is higher than that in most species of <i>Centaurea</i> in a strict sense. Molecular phylogenetic studies of the relationships of Cynareae genera (A. Susanna et al. 1995) place <i>Amberboa</i> as sister to the remaining genera of the Centaureinae.</p>
