Basal and lower stem leaves withered by anthesis; median stem leaves long petiolate; petiole 3-6 cm, glabrous, not winged, basally slightly expanded, not auriculate; blade abaxially pale green, triangular, 3-5 × 2-4 cm, membranous, abaxially glabrous, adaxially shortly scattered pilose or subglabrous, pinnately veined, base cordate or hastate, margin coarsely dentate, apically shortly obtuse-acuminate, mucronulate; upper leaves smaller. Uppermost leaves lanceolate or linear, margin remotely denticulate or subentire. Capitula discoid, nodding, solitary or rarely paired in axils of uppermost leaves, forming a terminal racemose cyme; peduncles cygneous, mostly shorter than subtending leaves, puberulent, not bracteolate. Involucres narrowly campanulate, 8-10 × 3-6 mm, calyculate; bracts of calyculus 3 or 4, linear, less than 1/2 as long as involucre, apically obtuse; phyllaries 8 or 9, rarely 13, oblong-linear or linear-lanceolate, 8-10 × 1-2 mm, herbaceous, puberulent or glabrous, margin narrowly scarious, apically subacute or obtuse and puberulent. Disk florets 15-18; corolla yellow, 7-7.5 mm, with ca. 3 mm tube and narrowly campanulate limb; lobes 5, ovate-triangular, ca. 1 mm, apically acute. Anthers ca. 2 mm, basally obtuse-auriculate; antheropodia rather short, basally somewhat dilated and rounded. Style branches ca. 0.8 mm. Achenes cylindric, ca. 4 mm, glabrous. Pappus white, ca. 6 mm.
