Perennials, 10-25(-50) cm (white or gray, floccose- or lanate-tomentose, hairs somewhat matted, sometimes with closely appressed hairs beneath the matted hairs, unevenly glabrate, especially proximal stems, adaxial faces of leaves, and phyllaries; rhizomes creeping or suberect). 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). Heads 1-4(-6 +). Involucres ± abruptly contracted to peduncles. Phyllaries usually 21, purplish (most of lengths, glabrate), (5-)7-10 mm. Ray florets usually 13 or 21; corolla laminae 10-15(-20) mm. Disc florets 50-80+; corollas orange or orange-yellow. Cypselae pubescent; pappi white. 2n = 46, 48. Flowering Jun-Aug. Alpine meadows, open tundra; 1000-3200 m; B.C., N.W.T., Yukon; Alaska, Mont., Wyo.; e Asia (Russian Far East). 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.
