Herbs, erect, rhizomatous. Rhizome thick, woody, creeping. Vegetative stem solitary, erect, ca. 35 cm, sparsely pubescent, glabrescent to glabrous, leafless except at apex. Flowering stem solitary, erect, scapiform, 35-60 cm tall, shortly branching, thinly arachnoid-tomentose, glabrescent. Leaves crowded, subrosulate at base of flowering stems; petiole 1-2.5 cm, not winged, slightly expanded at base; blade oblanceolate-obovate, 10-20 × 3-6 cm, membranous, abaxially sparsely arachnoid, glabrescent to subglabrous, adaxially scattered setulose, pinnately veined, lateral veins 10-14, arcuate-ascending, base cuneate-attenuate into petiole, margin shallowly sinuate-apiculate or repand-apiculate, apex subacute-acuminate. Flowering stem leaves few, remote, much smaller. Capitula discoid, numerous, arranged in rather dense 3-7-headed corymbs, terminal on short synflorescence branches, whole forming a somewhat attenuate narrowly paniculoid thyrse; peduncles 3-5 mm, densely fulvous tomentose, 1-or 2-bracteolate; bracts linear. Involucres cylindric, ca. 6 × 2-2.5 mm, calyculate; bracts of calyculus 3-5, ovate or ovate-oblong, 1/4-1/3 as long as phyllaries; phyllaries 5, narrowly oblong, 1-1.5 mm wide, herbaceous, margin narrowly scarious, glabrous, conspicuously 3-5-veined, apically triangular, obtuse, puberulent and dark colored. Ray florets absent. Disk florets 4 or 5; corolla yellow, ca. 9 mm, with ca. 2.5 mm tube and narrowly funnelform limb, exserted from involucre; lobes oblong-lanceolate, ca. 1.5 mm, apically acute. Anthers ca. 3.5 mm, anther tails ca. equaling antheropodia; appendages ovate-lanceolate; antheropodia stout, basally dilated. Style branches ca. 1.5 mm, fringed with long papillae, terminal tuft not conspicuously longer. Achenes ca. 4 mm, glabrous. Pappus ca. 8.5 mm, fulvous. Fl. Jul.
