Perennials, to 120 cm (stoloniferous, rosettes forming at stolon apices). Stems glabrous or moderately hirsute (branches spreading). Leaves: blades lanceolate to broadly ovate or elliptic (not lobed), herbaceous, bases attenuate to cordate, margins usually entire or serrate, sometimes lacerate, apices acute, faces glabrous or hirsute to strigose; basal petiolate, 5–30 × 1–8 cm; cauline petiolate, 2–25 × 0.5–7 cm, bases attenuate to cordate or auriculate. Heads borne singly or (2–7) in corymbiform arrays. Phyllaries to 2 cm. Receptacles hemispheric to ovoid; paleae 2.5–4 mm, (apical margins usually ciliate) apices obtuse to acute, abaxial tips usually glabrous. Ray florets 10–15; laminae elliptic to oblanceolate, 15–25 × 3–6 mm, abaxially strigose. Discs 12–16 × 10–18 mm. Disc florets 50–500+; corollas proximally yellowish green, brown-purple distally, 3–4.2 mm; style branches ca. 1.3 mm, apices rounded. Cypselae 2.2–4 mm; pappi coroniform, to 0.2 mm.
