Stem leaves 2-4(or 5), similar to radical ones; blade 1.5-2.5 cm, shortly petiolate; petiole slightly expanded and subamplexicaul at base; uppermost leaves sessile, bractlike, oblanceolate to linear, margin 3-5-lobulate or sometimes entire. Capitula usually 1-3, rarely more, arranged in terminal subcorymbs, ca. 2 cm in diam.; peduncles 2-3.5 cm, slender; bracteoles linear, 5-15 mm, margin entire or sometimes 2- or 3-denticulate. Involucres campanulate, hemispheric when flattened, 5-6 × 8-10 mm; phyllaries ca. 13, oblong-lanceolate, 1-1.5 mm wide, herbaceous, sparsely pubescent or subglabrous, inconspicuously 3-veined, margin scarious, apically acute, purplish and ciliate. Ray florets 13 or 14; corolla tube ca. 2 mm; lamina yellow, oblong, 10-11 × 2-3 mm, apically 3-denticulate. Disk florets numerous, 3.5-4 mm, with ca. 1.5 mm tube and campanulate limb; lobes ovate-lanceolate. Anthers oblong, basally obtuse, ca. 1.3 mm. Style branches recurved. Achenes cylindric, ca. 2 mm, glabrous, papillate. Pappus white, 2-3 mm. Fl. Apr-Sep. 2n = 48*.
