Herbs, perennial, weakly erect or subscandent, rhizomatous. Stems erect or weakly ascending, flexuous, to 70 cm, branched, angular, glabrous. Basal leaves soon withered; stem leaves sessile; blade oblong-elliptic or narrowly so, 3-5 × 0.5-1.5 cm, abaxially sparsely pilose on veins, adaxially glabrous, base auriculate; auricle small, sagittate-denticulate, semiamplexicaul; blade pinnatisect with oblong, obtuse-acuminate, remotely denticulate terminal lobe and 6-10 shorter, oblong, spreading or slightly ascending subentire or few-denticulate lateral lobes, margin revolute and shortly ciliate. Upper leaves smaller, linear-lanceolate, margin dentate or subentire. Capitula radiate, few in lax terminal corymbs; peduncles 3-5 cm, slender, glabrous, bracteate at base, with a few subulate 2-3 mm adpressed ascending bracteoles. Involucres campanulate, 5-7 × 5-7 mm, calyculate; bracts of calyculus ca. 8; phyllaries 13, linear or linear-lanceolate, 1-1.5 mm wide, herbaceous, glabrous, 3(-5)-veined, margin scarious, apically acutely to subobtusely acuminate and minutely ciliate-puberulent. Ray florets 7 or 8; corolla tube 2.5-3.5 mm; lamina yellow, oblong-linear, 5-6 × 1-2 mm, 4-veined, apically 3-denticulate. Disk florets many; corolla yellow, ca. 5.5 mm, with ca. 2.5 mm tube and narrowly campanulate limb; lobes ovate-lanceolate, ca. 1 mm. Anthers ca. 2 mm, basally obtusely long auriculate or shortly caudate, tails stout, slightly under 0.25 × as long as antheropodia; antheropodia rather elongated, basally slightly dilated. Style branches ca. 0.8 mm. Achenes cylindric, pubescent, basally slightly attenuate. Pappus white, 3.5-4.5 mm.
