Perennials, (25–)60–90+ cm. Stems erect, stramineous to red-brown, stipitate-glandular (at least distally). Cauline leaf blades spatulate or oblong to oblanceolate or lanceolate, 25–60(–90) mm, lengths 3–5(–7) times widths, bases cuneate to ± clasping, margins entire or serrate to denticulate (teeth apiculate), apices obtuse to acute, faces usually finely stipitate-glandular, sometimes glabrous (or scabridulous near margins) and gland-dotted. Heads in open to crowded, corymbiform to paniculiform arrays. Involucres broadly urceolate to globose, 8–15 × 12–20(–30) mm. Phyllaries in 6–9 series, spreading to appressed, linear or linear-attenuate to lance-linear, apices mostly looped to hooked (inner sometimes recurved to straight), ± terete, moderately to strongly resinous. Ray florets 20–30+; laminae 8–12 mm. Cypselae whitish to stramineous, 4–5.5 mm, apices ± coronate, faces striate or furrowed; pappi of 2 straight to curled, usually smooth, sometimes barbellulate, subulate scales 2.5–4+ mm, shorter than disc corollas.
