Herb, with basal rosette and a single flowering stem 0.3–1 m high; stem unbranched except for inflorescence, sparsely pilose with tubercle-based hairs. Basal leaves suberect, petiolate or nearly so, the petiole up to 13 cm long, blade narrowly elliptic or narrowly obovate, 6–30 cm long, 2.5–6 cm wide, base attenuate, margins sinuate and broad-dentate with callose tips, apex obtuse or acute, sparsely pilose beneath and with impressed glands, similar above but more scabridulous; cauline leaves absent or very few, the ones close to the base similar to the basal leaves but sessile with semi-amplexicaul base, the distal ones much smaller and very narrow. Capitula 8–16 mm long, heterogamous, several in fairly lax corymbs; stalks of individual capitula 1–10 mm long; phyllaries pale green, narrowly triangular, 4–9 mm long, acute, pubescent. Ray florets yellow, in a single row, tube filiform, 1.5–2.5 mm long, limb 5–8.5 mm long, 1.5–2 mm wide, 2–3-toothed, style 5–5.7 mm long; disc florets yellow, tube narrowly infundibuliform from a widened base, 4–4.5 mm long, lobes 0.7–0.9 mm long and slightly pilose; anthers brown, 1.8–2.6 mm long and eventually almost completely exserted, style 5–5.4 mm long. Achenes cylindric, 1.7–2 mm long, sparsely pilose; pappus whitish, 4–5 mm long.
