Plants 30–100 cm. Stems erect to ascending, green when young, fastigiately branched, glabrous, gland-dotted, resinous. Leaf-blades ascending, sometimes spreading when older, filiform to narrowly oblanceolate (adaxially sulcate to concave), 10–20 × 1–2 mm, midnerves not evident, apices acute, sometimes apiculate, faces glabrous, regularly gland-dotted (in circular, deep pits), resinous; axillary leaf fascicles sometimes present, shorter than subtending leaves. Heads in irregular cymiform arrays (to 7 cm wide). Peduncles 3–15 mm (bracts 3–20+, mostly leaflike, distal scalelike). Involucres turbinate, 3–5 × 3–5 mm. Phyllaries 12–20 in 3–4 series, tan, linear to lanceolate, 1–3.5 × 0.5–1 mm, unequal, mostly chartaceous, sometimes herbaceous-tipped, erect, midnerves raised, somewhat expanded apically, subapical resin ducts usually present, (margins scarious to narrowly membranous, glabrous or ciliate) apices erect, acute, sometimes apiculate, abaxial faces glabrous. Ray-florets 3–6; laminae 4–5 × 1–2 mm. Disc-florets 6–16; corollas 5–6 mm. Cypselae tan to brown, turbinate to narrowly oblanceolate, 3.5–4 mm (ribs ca. 5), villous; pappi off-white to brown, 3.5–5 mm. 2n = 18.
