Lower stem leaves similar to radical leaves. Median leaves sessile, oblong or oblong-lanceolate, 6-15 × 1-3 cm, smaller upward, base auriculate and amplexicaul, apex obtuse to acute. Upper leaves linear-lanceolate, bractlike. Capitula 2.5-3 cm in diam., 6-12 arranged in simple or compound subumbelliform terminal corymbs; peduncles 1.5-4.5 cm, sparsely pubescent, basally bracteate, not bracteolate, or with a linear-subulate bract in upper part, slightly dilated at apex. Involucres broadly campanulate or hemispheric, 5-6 × 6-7 mm, not calyculate; phyllaries 20-25, lanceolate, ca. 1.5 mm wide, herbaceous, with membranous margin, sparsely pubescent or glabrous, apically acuminate. Ray florets 13-15, corolla tube ca. 4 mm, glabrous; lamina yellow, oblong, ca. 10 × 2.5-3 mm, 4-veined, apically obtuse, 3-denticulate. Disk florets many; corolla yellow, 7-7.5 mm, with 3.8-4 mm tube and campanulate limb; lobes ovate-triangular, ca. 1.2 mm, apically papillose. Anthers linear-oblong, ca. 2 mm, basally obtuse, appendages ovate-lanceolate; style branches ca. 0.5 mm. Achenes cylindric, 2-2.5 mm, glabrous. Pappus white, 7-7.5 mm. Fl. Apr-May.
