Herbs, perennial, rhizomatous, with leafy stems, rarely subscapigerous. Stem solitary, erect, 40-80 cm tall, simple or branching into synflorescence, sparsely arachnoid, glabrescent. Basal leaves sometimes present at or sometimes withered and shriveled or shed by anthesis; basal and lowest stem leaves petiolate; petiole to 10 cm; blade ovate-elliptic or ovate-lanceolate to oblanceolate, 8-10(-20) × 3-7 cm, papery, abaxially sparsely arachnoid and ± glabrescent, adaxially glabrescent to glabrous, pinnately veined, lateral veins 16-18, base expanded, weakly cordate to cuneate or attenuate, margin dentate, apex obtuse, unlobed or lyrate-pinnately lobed with 2-8 basal lateral lobes decreasing in size toward base of leaf. Median stem leaves oblong or oblanceolate-oblong, 5-22 × 2-7 cm, base auriculate; auricle dentate or lobulate, subamplexicaul, lyrate-pinnatifid or pinnatifid, very variable in dissection, with large to small, ovate to oblong-lanceolate, dentate or lobulate terminal lobe and 10-16 oblong to narrowly oblong-lanceolate, entire or usually irregularly serrate-dentate or lobulate spreading or somewhat ascending lateral lobes. Upper leaves smaller, oblong-lanceolate to oblong-linear, margin coarsely pinnate-dentate. Capitula radiate, numerous, arranged in terminal corymbs or compound corymbs; peduncles 5-25 mm, ± arachnoid-tomentose or fulvous puberulent, ± glabrescent, linear-bracteate, with 2 or 3 linear-subulate bracteoles. Involucres campanulate, 3-4 × 3-4 mm, calyculate; bracts of calyculus 8-10, linear-subulate, 2-3 mm; phyllaries 10-13, oblong-lanceolate, herbaceous, fulvous puberulent toward base, margin broadly scarious, apically acute or acuminate, brownish black and pubescent. Ray florets 10-13; corolla tube ca. 2.5 mm; lamina yellow, oblong, ca. 6.5 × 2 mm, 4-veined, apically obtuse, 3-denticulate. Disk florets many; corolla yellow, 5-5.5 mm, with ca. 2.5 mm tube and funnelform limb; lobes ovate-triangular, ca. 0.8 mm, apically acute. Anthers ca. 2 mm, basally obtuse-auriculate, appendages ovate-lanceolate; antheropodia slightly elongated, basally somewhat dilated. Style branches ca. 1 mm. Achenes cylindric, 2-2.5 mm, all or disk achenes sparsely pubescent, sometimes ray achenes or rarely all achenes glabrous. Pappus dirty white, straw-colored, or rarely rufous, ca. 4 mm, present in all achenes or sometimes scant or absent in ray achenes, those in ray achenes deciduous. Fl. Apr.
