General Description
Taprooted perennial herbs, often with a branched caudex. Stems erect, often branched above, 6–40 cm. Herbage sparsely to densely tomentose. Leaves cauline and mainly basal, petiolate, 1–8 cm long; blades deeply 1–2-times pinnately divided into mostly remote, linear lobes. Inflorescence corymbiform with few to numerous heads. Heads discoid; involucres hemispheric, 6–11 mm high; phyllaries 5–13, lanceolate to oblong, tomentose, in 2–3 unequal series, membranous-margined; receptacle flat, naked. Disk flowers perfect, yellow, 2–4 mm long, glandular; tubes ca. as long as the dilated throat; style branch appendages hairy. Pappus of several short, hyaline scales. Achenes obconic, 4–5-angled, 4–5 mm long, densely strigose (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).

We have varieties luteus (Nutt.) B.L. Turner and polycephalus (Osterh.) B.L. Turner.
