Stems 1–20, ascending to erect, (24–)37–85(–108) cm, densely strigose, becoming moderately hispido-strigose and densely stipitate-glandular distally. Cauline leaves sessile, light green or silvery-whitish; proximal oblanceolate 12–38 × (3–)4.7–7(–8.5) mm, margins entire, undulate, faces moderately to densely hispido-strigose, very sparsely to moderately stipitate-glandular; distal lanceolate, 10–20 × 2–6 mm, reduced distally, stiff, bases rounded, margins usually strongly undulate, often more stipitate-glandular and less ciliate than faces, sparsely to extremely densely short-strigose, sparsely to densely glandular. Peduncle bracts 3–5, leaflike, greatly reduced, none enlarged and subtending heads. Involucres 7–10(–12) mm. Ray florets 4–14; laminae 3.5–5.9(–9) mm.
