Median stem leaves sessile, linear-lanceolate or oblong, 4.5-14 × 1-4 cm, otherwise like lower leaves, basally subauriculate or auriculate; auricle semiamplexicaul. Uppermost leaves smaller, linear, bractlike, apically attenuate, margin entire in upper part. Capitula radiate, rather numerous, arranged in a terminal compound corymb; peduncles 7-20 mm, linear-bracteate, with 2-4 linear-subulate, 2-3 mm bracteoles. Involucres campanulate, 5-6 × 2.5-4 mm, calyculate; bracts of calyculus 5; phyllaries ca. 13, linear or linear-lanceolate, ca. 6 × 1-1.5 mm, herbaceous, puberulent, margin broadly scarious, apically subobtuse, purplish and minutely puberulent. Ray florets 7 or 8; corolla tube ca. 4 mm, glabrous; lamina yellow, oblong, ca. 8 × 2.7 mm, 4-veined, apically 3-denticulate. Disk florets many; corolla yellow, ca. 6 mm, with narrow ca. 3 mm tube and funnelform limb; lobes ovate-oblong, ca. 1 mm, apically acute, papillose. Anthers ca. 2 mm, basally distinctly obtuse-auriculate, appendages ovate-oblong; antheropodia distinctly somewhat dilated toward base. Achenes cylindric, ca. 3 mm, glabrous. Pappus white, ca. 5.5 mm.
