Characteristics

Stems sparsely hispido-strigose proximally. Cauline leaves: proximal subsessile to sessile, blades oblanceolate, margins entire, flat or weakly undulate, apices acute, faces usually moderately, rarely densely hispido-strigose, sparsely stipitate-glandular; distal sessile, blades oblanceolate or lanceolate, (13–)21–40 × (4–)5–7(–8) mm, often little reduced distally, margins flat, with large spreading cilia along much of length, faces moderately long-strigose, sparsely to moderately stipitate-glandular. Peduncle bracts 1–4, grading from leaves, lanceolate to linear distally, faces sparsely to moderately long hispido-strigose, sparsely to moderately stipitate-glandular; sometimes 1–3+ larger leaflike bracts subtending and exceeding involucres. Involucres 9–12.6(–15) mm. Ray florets (9–)12–18(–21); laminae 9–15(–20) mm. Disc florets: corolla tubes and throats glabrate, lobes glabrate to sparsely strigose (hairs 0.2–0.7(–1) mm). Cypsela faces moderately to densely strigose.
