General Description
Taprooted perennial with a simple or branched caudex. Stems mostly ascending, woody at the base, 10–50 cm. Herbage strigose to hirsute, often stipitate-glandular. Leaves cauline, petiolate below; blades oblanceolate to obovate, 1–5 cm long, entire. Heads radiate, several in leafy-bracted corymbiform arrays; peduncles 0–3 cm long. Involucre narrowly campanulate, 5–10 mm high; phyllaries imbricate in 4 to 5 series, green, narrowly lanceolate, white-margined, glabrate to strigose, sometimes glandular; receptacle nearly flat, glabrous. Ray flowers 10 to 20, yellow, female, fertile; ligules 5–9 mm long. Disk flowers 20 to 50, yellow, perfect; corolla 4–7 mm long; style branches flattened with elongate appendages. Pappus dimorphic, short, of outer scales and inner capillary bristles. Achenes obconic, 2–3 mm long, strigose with 4 to 8 ribs (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).

In Montana we have confirmed vouchers for varieties villosa, minor (Hook.) Semple, and foliosa (Nutt.) V.L.Harms. Semple (1996, University of Waterloo Biology Series) reported variety depressa (Rydb.) Semple for Park County, MT, with most of the subspecies' distribution occurring in western WY, but vouchers have not been seen or confirmed recently for MT.
