Sinosenecio eriopodus is similar to S. villifer but is easily distinguished by the ovate-cordate leaf blade, which is abaxially densely lanate with fulvous hairs or sericeous. Specimens from Shizhu, E Chongqing, previously referred to S. villifer, belong to this species. Specimens from Luding, W Sichuan, previously identified as this species, actually belong to S. subrosulatus.
