Prenanths faberi hemsl.的属位置菊科(菊科-菊科)长期以来一直是一个有争议的问题。最近的分子系统发育分析表明，它包含在Faberia hemsl属中。细胞学研究表明，该种的染色体数目为2n=34，核型相当对称，由26条中值着丝粒(M)和8条亚中值着丝粒(Sm)染色体组成，染色体长度在1.72-4.20m之间。将该物种转移到Faberia得到了强烈的支持。
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 m. 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.
