Perennials, 30–200 cm (bases woody). Stems branched, pubescent. Leaves mostly opposite (alternate in vars. gracillima and texana); petioles 0–10 mm; blades 1-nerved or 3-nerved from bases, lanceolate, lance-linear, lanceovate, lance-rhombic, linear, or oblong, 25–100 × 0.5–40 mm, bases acute, margins entire or ± dentate (often revolute), apices obtuse to acuminate, faces glandular-pubescent. Heads in paniculiform or corymbiform arrays. Peduncles 5–100 mm, glandular-pubescent. Involucres cylindric to narrowly campanulate, 7–15 mm. Phyllaries 22–26 in 4–6 series, green to stramineous, sometimes purple-tinged, 3–7-striate, unequal, margins scarious (often ciliate); outer ovate to lanceovate (puberulent, often densely glanddotted, apices acute to acuminate), inner lanceolate (± glanddotted, apices obtuse to aristate). Florets 6–35; corollas pale-yellow, yellow-green, pinkish lavender, or maroon, 4.5–6 mm. Cypselae 2.7–5.5 mm, glabrous or strigose, sometimes hispidulous or velutinous and/or glanddotted; pappi of 20–28 white or tawny, usually plumose or subplumose, sometimes barbellate, bristles.
