Perennials, 20–50+ cm; stoloniferous and rhizomatous (rhizomes horizontal to suberect). Stems 1 or multiple, loosely clustered, usually glabrous, sometimes tomentose proximally and in leaf axils. Basal leaves (and proximal cauline) petiolate; blades orbiculate, ovate, or obovate, 40–100+ × 20–80+ mm, bases tapering, rounded, or abruptly contracted, margins crenate, dentate, or serrate. Cauline leaves gradually reduced (sessile, clasping; pinnatisect or sublyrate). Heads 6–15+ in open or congested, corymbiform arrays. Peduncles bracteate, glabrous or proximally tomentose. Calyculi conspicuous. Phyllaries 13 or 21, green (tips sometimes reddish), 3–6 mm, glabrous or floccose-tomentose proximally. Ray florets 8–13(–21); corolla laminae 7–10 mm. Disc florets 40–50+; corolla tubes 2–3 mm, limbs 2–3 mm. Cypselae 1–1.5 mm, glabrous or hirsute on ribs; pappi 3–6 mm. 2n = 44, 88, 90.
Phenology: Flowering late Feb–Apr (south), early Apr–early Jun (north).
Habitat: Meadows in deciduous woodlands, wet ditches, stream banks, rocky hillsides
Elevation: 0–2500 m
