Herbage villosulous or tomentose to sparsely hispidulous (hairs short, crisped, white), not resinous. Leaf blades narrowly oblanceolate, 5–10(–18) mm, margins usually toothed or lobed (teeth or shallow lobes in 1–2(–3), pinnately arranged pairs), sometimes entire. Involucres 5–6 × 6–7 mm. Phyllary apices greenish, not aristate, gland-dotted, without resin pockets. Florets 19–28; corollas 4–5 mm. Cypsela ribs not forming apical horns.
