The generic placement of Prenanthes faberi Hemsl. (Compositae–Cichorieae) has long been a controversial matter. Recent molecular phylogenetic analyses indicate its inclusion in the genus Faberia Hemsl. The present cytological investigation shows that this species has a chromosome number of 2n = 34 and a fairly symmetric karyotype consisting of 26 median centromeric (m) and 8 submedian centromeric (sm) chromosomes varying in length between 1.72–4.20 μm. The karyological characters of P. faberi are remarkably consistent with those reported previously in species of Faberia . The transference of this species to Faberia is strongly supported.
