    Stems 1–50+, decumbent to erect (sometimes brown or reddish-brown, sometimes whitish distally, sometimes ± brittle), sparsely to densely hispido-strigose, sparsely to abundantly long-hispid, eglandular or sparsely to densely stipitate-glandular.
    Leaves generally not crowded;
    proximal cauline petiolate, blades oblanceolate, (90–) 220–400 (–600) × (2–) 4–8 (–13) mm, bases cuneate, margins flat, usually entire, rarely with 1–2 apical teeth, strigoso-ciliate, sparsely to abundantly long-hispido-strigose proximally, apices acute to obtuse, sometimes mucronate, faces sparsely to densely hispido-strigose, eglandular or sparsely to densely stipitate-glandular;
    distal sessile, blades usually lanceolate or oblanceolate to oblong, rarely ovate or lanceolate-triangular, (4–) 15–28 (–42) × (1.5–) 3.5–7 (–12.5) mm, bases attenuate to convex-cuneate to rounded, margins usually flat, rarely remotely undulate, strigoso-ciliate, sparsely to abundantly long-hispido-strigose proximally, apices acute to obtuse, sometimes mucronate, faces sparsely to densely hispido-strigose, eglandular or sparsely to densely stipitate-glandular.
    Heads 1–16 (–42), in usually open, corymbiform, rarely paniculiform arrays.
    Peduncles (4–) 15–41 (–98) mm, sparsely to densely hispido-canescent, eglandular or sparsely to densely stipitate-glandular;
    bracts 1–7+, usually linear-oblanceolate, rarely leaflike and linear-oblanceolate, usually greatly reduced, margins usually flat, rarely remotely undulate, strigoso-ciliate, sparsely to abundantly long-hispido-strigose proximally, apices acute, sometimes mucronate, faces sparsely to densely hispido-strigose, eglandular or sparsely to densely stipitate-glandular;
    rarely 1–2 leaflike, oblanceolate bracts subtending heads.
    Involucres narrowly cylindric to campanulate, (5–) 6–9.5 (–13) mm.
    Phyllaries in 4–5 series, lanceolate to linear-lanceolate or triangular-lancelate, unequal (outer 1/5–1/3 length of inner), margins scarious, sometimes reddish purple distally, ciliate distally or apically, faces sparsely to densely strigose, eglandular or sparsely to moderately stipitate-glandular.
    Ray-florets (5–) 10–20 (–38);
    laminae (3.5–) 6.5–11 (–20) × 1–2 (–3) mm.
    Disc-florets (10–) 20–50 (–85);
    corollas barely ampliate, (4–) 5–6 (–8) mm, glabrous or glabrate (few, minute hairs), lobes 0.4–0.75 (–1) mm, glabrous or glabrate (hairs 0.1–0.35 mm).
    Cypselae monomorphic, obconic, compressed, 1.7–2.7 (–3.4) mm, ribs 4–8 (–10) (rarely brownish), faces sparsely to moderately strigose;
    pappi off-white, outer of linear scales 0.25–1 mm, inner of 30–45 bristle (4–) 5–6.5 (–8.5) mm, longest weakly clavate (usually equaling or longer than corollas).
