Characteristics

Herbs, scapigerous or subscapigerous. Rhizomes 5-10 mm in diam., collar densely fulvous tomentose and clad in persistent petiole bases. Stems solitary, erect, subscapiform, 10-35 cm tall, slender, simple, brown villous in lower part, sparsely so to subglabrous in upper part. Radical leaves few, rosulate, long petiolate; petiole 2-6 cm, rather stout, densely fulvous villous, basally somewhat expanded; blade adaxially green or deep green, suborbicular or reniform, 2-7 × 2.5-9 cm, thickly papery or subleathery, abaxially densely white tomentose or sometimes sparsely villous and glabrescent, and then often deep purplish red, adaxially sparsely to sometimes densely fulvous hispid, palmately 5-7-veined, base cordate, margin coarsely repand or dentate with ovate-deltoid or shallowly ovate-deltoid mucronulate teeth. Stem leaves usually 1-5, similar to radical ones but smaller upward on stem and with shorter petioles slightly expanded but not auriculate at base. Uppermost leaves bractiform, few, linear or linear-lanceolate, 1-1.5 cm, apically acute. Capitula (1 or)2-7 or more arranged in terminal corymbs, 1.5-1.8 cm in diam.; peduncles 1-5.5 cm, slender, sparsely puberulent or subglabrous, usually bracteate at base and 1-3-bracteolate in upper part; bracts and bracteoles linear, 3-6 mm, apically callose-mucronulate. Involucres campanulate, hemispheric when flattened, 5-8 × ca. 7 mm, calyculate; calyculus of 8-10 bracteoles; bracteoles linear, 3-5 mm, apically callose-mucronulate. Phyllaries ca. 13, oblong-lanceolate, 6-7 × 1.5-2.5 mm, herbaceous, glabrous or subglabrous, apically ± acute, reddish purple and ciliate. Ray florets ca. 13, uniseriate; corolla tube ca. 2.5 mm, glabrous; lamina yellow, oblong or broadly oblong, ca. 7 × 2-3 mm, 4-veined, apically 3-denticulate, obtuse. Disk florets: corolla yellow, 3.5-4 mm, with ca. 2 mm tube and campanulate limb; lobes ovate-lanceolate, ca. 1 mm, apically acute. Anthers ca. 1.3 mm, basally obtuse, appendages ovate-oblong. Style branches ca. 0.7 mm. Achenes cylindric, 1.5-2 mm, ribs pubescent, papillate. Pappus white, 3.5-4 mm. Fl. May-Oct, fr. Jun-Nov. 2n = 48*.
