Stems single or loosely clustered. Leaves basal and cauline; petioles winged (passing into blades); blades lanceolate to ovate, 3–6(–10) × 1–2.5 cm, margins wavy or subentire to denticulate (cauline similar, narrower, sessile, weakly-clasping, bractlike).

Disc florets 50–80+; corollas orange or orange-yellow. Cypselae pubescent; pappi white. 2n = 46, 48.

Discussion
For Russia, S. S. Kharkevich (1985+, vol. 6) and I. M. Krasnoborov et al. (1987+, vol. 13) treated this taxon as T. tundricola subsp. lindstroemii. It has been widely known in American literature as Senecio fuscatus, a misapplied name.
