Polymorphic annual herb, 15–150 cm high; stems erect, either leafy in the lower half or leafless and leaves then in basal rosette. Basal leaves up to 1.5–37 x 0.5–14 cm, obovate to spathulate, obtuse to acute, sinuate-dentate to runcinate, margin denticulate with white stiff teeth; stem leaves smaller, lanceolate, pinnatifid, sagittately auriculate. Synflorescences with many capitula, of few to many spreading-erect flowering axes. Capitula often clustered at the nodes, with 12–35 florets; involucre slender, 9–13 mm long, inner phyllaries 8. Florets pale yellow, ligule 5.5–6 mm long, linear; anthers (appendages excluded) 1.1–1.3 mm long. Achenes 3.2–4.5 mm long, the inner ones with 4 main ribs, greyish, weakly wrinkled, cuspidate to shortly rostrate, the marginal ones with a beak 1/8–1/4 of the achene length and 5 main ribs, sharply wrinkled, black (occasionally all pale); pappus 7–8 mm long, persistent, of outer downy hairs and inner bristles.
