Saussurea dutaillyana, characterized by dense brown indumentum of articulate hairs on stem and petioles, by basal leaves crowded in a rosette, and by ample lax paniculiform synflorescences, may deserve separate taxonomic status. It has been accepted in several provincial floras and is recorded from Chongqing, Henan, Hubei, S Shaanxi (Qin Ling), Sichuan, and Zhejiang.

The following species, Saussurea oligantha, also belongs to this species group and is not well separated from S. cordifolia.
