Perennials or subshrubs, 40–150 cm. Stems (simple or branched) glabrous or with scabrous lines, not glaucous. Leaves usually ascending; blades (1–)3- or -5-nerved, linear to lanceolate, 40–100(–120) × 1.4–4(–8) mm, lengths 12–49 time widths, gradually reduced distally, firm-herbaceous, margins scabrous, apices acuminate, faces abundantly and prominently gland-dotted (29–49 dots per mm²), glabrous or midveins with hairs. Heads (some or all) pedunculate (rarely all glomerate), usually in flat-topped to slightly rounded, arrays (25–)35–60% of plant heights. Involucres obconic, (4–)4.5–6.2 mm. Phyllaries usually green-tipped, outer ovate, inner linear-oblong, apices obtuse to acute (± strongly resinous). Ray florets 9–13(–16). Disc florets 3–9; corollas (3–)3.3–4.8 mm. 2n = 36, 54.
Phenology: Flowering Aug–Sep.
