Flowering stem solitary, erect, scapiform, 20-50 cm tall, branching from near base or in upper part, arachnoid-tomentose, glabrescent. Leaves crowded, subrosulate at base of flowering stems, sessile; blade oblanceolate-oblong or elliptic, 12-22 × 4-6 cm, papery, both surfaces sparsely floccose-tomentose and glabrescent, pinnately veined, lateral veins 10-12, arcuate-ascending, base cuneate or attenuate into a 4-10 cm, gradually attenuate, winged petiole, slightly amplexicaul, margin remotely shortly mucronately sinuate-serrate, apex acute-acuminate. Capitula discoid, numerous, arranged in rather dense orbicular 3-12-headed corymbs, terminal on usually rather short or strictly ascending synflorescence branches, whole forming a rather narrow paniculoid thyrse; peduncles short, ca. 2 mm, arachnoid-tomentose, bracteate, 1-bracteolate; bracts and bracteoles linear, to 10 mm, sparsely tomentose or subglabrous. Involucres cylindric, ca. 6 × 1.5-2 mm, calyculate; bracts of calyculus 3-5, linear, ca. 1/2 as long as phyllaries; phyllaries 5, oblong-linear, triangular-acuminate, herbaceous, glabrous, margin scarious, apically subobtuse, shortly barbellate and purplish. Ray florets absent. Disk florets 5 or 6; corolla yellow, ca. 8 mm, with ca. 3.5 mm tube and narrowly funnelform limb, exserted from involucre; lobes ovate-oblong, 1-1.2 mm, apically acute. Anthers ca. 2.5 mm; anther tails ca. 0.75 × as long as antheropodia; appendages ovate-lanceolate; antheropodia rather long, robust, basally distinctly dilated. Style branches ca. 1 mm, fringed with abundant, moderately long papillae, those of central tuft somewhat exceeding laterals. Achenes (immature) 1.7-2 mm, glabrous. Pappus white, ca. 5.5 mm. Fl. Oct-Dec.
