Recent molecular phylogenetic studies have demonstrated extensive paraphyly of Asterser.Albescentes Y.Ling. This woody-based shrubby group is both morphologically and molecularly distinct from the genus L. The series is characterized by its shrubby habit with multiple branches, cauline leaves with revolute or flat margins, radiate capitula, keeled phyllaries, and multinerved achenes. We redefine a more natural circumscription of this series by reinstating Nees with nomenclatural priority. A taxonomic synopsis of this series is presented herein. is recognized and described as a distinct genus (Astereae, Asteraceae) to accommodate 7 shrubby species (6 endemic to China) formerly placed in Asterser.Albescentes. A total of 19 new combinations are proposed, e.g., (DC.) Z.X.Fu, (incl. 10 varieties), (Hand.-Mazz.) Z.X.Fu, (incl. 2 varieties), (Grierson) Z.X.Fu, , (Hand.-Mazz.) Z.X.Fu, , (Hand.-Mazz.) Z.X.Fu, , (Y.L.Chen) Z.X.Fu, , and (C.K.Schneid.) Z.X.Fu, Formal typifications, synonyms, illustrations, distribution maps, and an identification key to the species of are also provided herein.

最近的分子系统发育研究表明，紫菀属白背系（Asterser.Albescentes Y.Ling）存在广泛的并系性。这个以木本为基的灌木类群在形态和分子上都与紫菀属（L.）不同。该系的特征是具有多分枝的灌木习性、具反卷或平边缘的茎生叶、辐射状头状花序、具龙骨状的总苞片以及多脉的瘦果。我们通过恢复具有命名优先权的紫菀属白背系（Nees）来重新定义这个系更自然的范围。本文给出了该系的分类大纲。紫菀属白背系（Asterser.Albescentes）被认可并描述为一个独特的属（菊科紫菀族），以容纳以前置于紫菀属白背系（Asterser.Albescentes）中的7个灌木物种（6个为中国特有）。总共提出了19个新组合，例如，（DC.）Z.X.傅，（包括10个变种），（Hand.-Mazz.）Z.X.傅，（包括2个变种），（Grierson）Z.X.傅，，（Hand.-Mazz.）Z.X.傅，，（Hand.-Mazz.）Z.X.傅，，（Y.L.陈）Z.X.傅，，以及（C.K.施奈德）Z.X.傅，本文还提供了正式的模式指定、同义词、插图、分布图以及该属物种的检索表。
