Perennials, (50–) 60–100 (–120) cm (caudices fibrous-rooted). Herbage sparsely floccose-tomentose, unevenly glabrescent. Stems single. Leaves evenly distributed; petiolate; well-developed mid leaves: blades lanceolate to oblong, (8–) 10–15 (–18) × (2–) 3–5 (–9) cm overall, margins deeply dentate or irregularly pinnate-lobed to laciniate; distal leaves sessile, weakly clasping. Heads 8–20 in corymbiform arrays. Calyculi of 3–8+ linear to filiform bractlets (lengths 1/2–3/4+ phyllaries). Phyllaries ± 13 or ± 21, 5–8 mm, tips green. Ray-florets ± 8 or ± 13; corolla laminae 8–12 (–20) mm. Cypselae glabrous.


Phenology: Flowering late summer.
Habitat: Moist meadows, conifer-dominated sites
Elevation: 1400–2700 m
