Leaves mostly cauline (proximal internodes elongate; petioles prominently ciliate, hairs spreading, thick-based); blades linear to linear-oblanceolate, 20–40 × 1–1.5 mm (on proximal 1/2–2/3 of stems), (bases relatively thin, not sheathing) margins entire, hispido-ciliate, faces strigose. Heads 1. Involucres 3.5–4 × 5–10 mm. Phyllaries in 2–3 series, hirsuto-villous, sometimes minutely glandular. Ray florets 25–40; corollas yellow, drying dark yellow (sometimes fading on drying and appearing whitish or creamy), 4–9 mm, laminae coiling. Disc corollas 2.5–3 mm. Cypselae 1.6–1.8 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 15–25 bristles.
