Perennials, (10–)25–70 cm. Stems erect, stramineous to reddish, glabrous. Cauline leaf blades oblong, spatulate, or oblanceolate to linear, 15–45(–85) mm, lengths mostly 3–8 times widths, bases ± cuneate, margins serrate (teeth from bases to apices or mostly toward apices, apiculate to setose), entire, or (proximal leaves) pinnately lobed to coarsely toothed, apices acute, faces glabrous (or scabridulous near margins), sparsely, or not at all, gland-dotted. Heads usually in corymbiform to paniculiform arrays, rarely borne singly. Involucres usually campanulate to obconic, sometimes hemispheric, 4–11 × 8–17 mm. Phyllaries in 4–6 series, linear to ± lanceolate, usually appressed, sometimes weakly reflexed or spreading, apices slightly recurved to straight, subulate or acuminate to deltate, slightly to strongly resinous. Ray florets 0 or 8–26; laminae (5–)7–10 mm. Cypselae stramineous to brown, 2.5–4 mm, apices coronate or knobby, faces striate to furrowed; pappi of 2–4 straight or weakly contorted, smooth setiform awns or subulate scales 2–5 mm, shorter than disc corollas. 2n = 12.
