Median stem leaves sessile, thinly papery, abaxially pubescent on main veins, adaxially shortly adpressed pubescent to glabrous, pinnately lobed, with small terminal lobe and 30-40 spreading or slightly ascending, oblong-lanceolate or lanceolate, acute-acuminate, irregularly sharply dentate or lacerate-lobulate lateral lobes, basally often auriculate; auricle broad, deeply incised, amplexicaul, sometimes absent. Upper leaves smaller, with narrow, linear-lanceolate or linear, entire or few-dentate lobes. Capitula radiate, numerous, arranged in terminal compound corymbs; peduncles 3-8 mm, slender, fulvous pubescent, linear-bracteate, with 2 or 3 linear bracteoles.

Ray florets 5; corolla tube ca. 2.5 mm, sparsely puberulent above; lamina yellow, oblong, ca. 4.5 × 1 mm, 4-veined, apically 3-denticulate. Disk florets 11-13; corolla yellow, ca. 4.5 mm, with ca. 2 mm tube and funnelform limb; lobes oblong-lanceolate, ca. 1 mm, apically acute, papillose. Anthers ca. 1.5 mm, basally obtuse-auriculate, appendages ovate-lanceolate; antheropodia rather small, basally slightly dilated. Style branches ca. 0.5 mm. Achenes cylindric, ca. 2 mm, glabrous.
