Herbs, rhizomatous. Rhizome thick, woody, branching. Vegetative stem creeping, ascending, or erect, 30-50 cm, leafless in lower part, leafy in upper part or at apex only, fulvous tomentose or villous. Flowering stem solitary, erect, ± subscapiform, 20-60 cm tall, tomentose or villous. Leaves at base of flowering stems petiolate, subrosulate or somewhat distant; petiole 5-10 cm, broadly to narrowly winged, at least toward base, obscurely to distinctly auriculate; auricle subamplexicaul, sparsely dentate or entire; blade broadly ovate to lanceolate, 9-22 × 4.5-12 cm, membranous, abaxially pubescent or shortly villous especially on veins, adaxially sparsely to densely finely setulose, pinnately veined, lateral veins 10-12, arcuate-ascending, base cordate, truncate, or broadly cuneate, margin obscurely sinuate and minutely mucronulate-denticulate to distinctly mucronulate-serrate or coarsely and irregularly mucronulate-dentate, apically acute-acuminate. Flowering stem leaves usually few, smaller, sessile, ovate-oblong or elliptic to oblanceolate-oblong or lanceolate-oblong; upper leaves often apically attenuate, basally subamplexicaul. Capitula heterogamous, disciform, or minutely radiate, rather few to very numerous, arranged in narrowly to broadly pyramidal thyrsoid corymbs or branched thyrsoid panicles; peduncles 1-3 mm, densely setose or tomentose, minutely bracteate, 1- or 2-bracteolate. Involucres cylindric, 5-7 × ca. 1.5 mm, very shortly calyculate; bracts of calyculus few; phyllaries 4 or 5, oblong-linear, 0.5-1 mm wide, herbaceous, usually densely setulose, margin narrowly scarious, apically obtuse. Ray florets 2; corolla 2-3.5 mm, truncate or minutely radiate, shorter than style. Disk florets 2 or 3(or 4); corolla yellow, 7-7.5 mm, with 2.5-3 mm tube and funnelform limb; lobes ovate-oblong, 1-1.2 mm, apically acute. Anthers ca. 3 mm; anther tails 0.3-0.75 × as long as antheropodia; appendages ovate-oblong; antheropodia somewhat elongated, stout, basally dilated. Style branches ca. 1 mm, fringed with rather short papillae and with a rather short and scant terminal tuft. Achenes ca. 1.5 mm, puberulent or glabrous. Pappus white, 5-6 mm. Fl. Aug-Nov.
