Perennials, 40–80 (–120) cm. Stems erect, stramineous to reddish, glabrous (resinous). Cauline leaf-blades oblong to oblanceolate or linear, 15–50 (–70) mm, lengths 3–6+ times widths, bases weakly clasping, margins usually entire, sometimes serrate (teeth mostly toward apices, apiculate), apices acute, faces glabrous, densely gland-dotted. Heads in paniculiform arrays. Involucres campanulate to obconic, 7–10 × 5–10 mm. Phyllaries in 4–7 series, linear to lanceolate, ± appressed, apices slightly recurved to nearly straight (outermost sometimes nearly patent), attenuate, slightly resinous. Ray-florets 5–13; laminae 3–5 (–7) mm. Cypselae stramineous to brown, 2.5–4 mm, apices knobby, faces striate (angles ± ribbed); pappi of 2 straight, smooth, setiform awns 3–4 mm, shorter than to nearly equaling disc corollas. 2n = 24.
