Herbs, scapigerous. Rhizomes 5-10 mm in diam., clad in persistent brown petiole bases. Stems solitary, sometimes 2-5, erect, scapiform, 10-65 cm tall, villous with brown hairs, especially in lower part, fulvous tomentose near apex, with 1 or 2 shortly petiolate bractlike leaves in upper part.

Capitula 1.5-2 cm in diam., 1-7(-10 or more), arranged in terminal corymbs, at first rather dense, becoming lax; peduncles 1-6 cm, slender, pubescent or subglabrous, with basal bract and 2 or 3 bracteoles; bracts and bracteoles linear or linear-spatulate, 5-10 mm. Involucres campanulate, 5-7 × 5-7 mm, not calyculate; phyllaries ca. 13, lanceolate or broadly lanceolate, 6-7 × 1-1.5 mm, herbaceous, inconspicuously 3-veined, puberulent, margin broadly scarious, apically acuminate or obtuse, ciliate at apex and on upper margin.
