Leaves ascending-spreading; blades cuneate to spatulate, 2–25 × 2–16 mm, midnerves evident or faint, (margins usually flat) apices rounded, obtuse, or retuse, sometimes mucronate, faces glabrous, gland-dotted (in pits), thickly resinous; axillary leaf fascicles rarely present. Heads usually borne singly, sometimes in rounded, cymiform arrays (to 5 × 8 cm). Peduncles 2–10 mm (bracts 0–10+, scalelike). Involucres turbinate to narrowly campanulate, 6–12.5 × 4–14 mm. Phyllaries 20–60 in 3–7 series, tan, ovate to lanceolate, 2–6 × 0.5–2.5 mm, unequal, mostly chartaceous, sometimes each with herbaceous subapical patch, midnerves evident on proximal 1/2 or throughout, subapical resin ducts 0 or slightly darker, thickened and expanded, (margins membranous, weakly lacerate) apices acute to acuminate or obtuse, abaxial faces glabrous. Ray florets 0(–7); laminae 3–4.3 × 1–1.5 mm. Disc florets 7–70; corollas ca. 5.5 mm. Cypselae tan to brown, turbinate, 2.5–3 mm, sericeous to villous; pappi off-white to brown, 6.5–8 mm. 2n = 18.
