    woody caudices or rhizomes.
    Stems decumbent to ascending or erect, sometimes branched distally, glabrous or strigose, strigillose, hispid, or short-villous.
    petiolate (proximal) or sessile (proximal and distal, latter sometimes subpetiolate);
    proximal blades sometimes 3-nerved, ovate-oblanceolate, margins often serrate, faces glabrous or densely hairy;
    distal sometimes 3-nerved, glabrous or sparsely to densely scabrous, strigillose, or villous, sometimes stipitate-glandular, sometimes resinous.
    Heads usually radiate, sometimes discoid, (1–) 2–1500+ in racemiform (club-shaped or pyramidal), paniculiform or corymbo-paniculiform, sometimes secund arrays.
    Involucres campanulate to cylindric (often spreading upon drying), 3–12 × 1.7–10 mm.
    Phyllaries 10–35 in 3–5 series, midnerves usually ± swollen and translucent, sometimes plus 2–5 secondary nerves (striate, flat), linear-lanceolate to oblong or ovate, unequal to rarely subequal, margins scarious, (apices rounded to acute or attenuate), faces glabrous or sparsely pilose or puberulent, sometimes minutely stipitate-glandular, sometimes resinous.
    Receptacles slightly convex, pitted, epaleate.
    Ray-florets (0–) 2–15 (–24), pistillate, fertile;
    corollas yellow, rarely white (usually glabrous).
    Disc-florets 2–35 (–60), bisexual, fertile;
    corollas yellow, ± ampliate, tubes shorter than throats (usually glabrous), lobes 5, erect to spreading, triangular to narrowly lanceolate;
    style-branch appendages broadly to narrowly triangular (lengths 0.7–1 times stigmatic lines).
    Cypselae narrowly obconic to cylindric, sometimes somewhat compressed, ribs usually 8–10 (either darker and sometimes translucent or lighter than bodies), glabrous or moderately strigillose;
    pappi persistent, outer setiform scales (0.25–0.5 mm; rarely present) plus 2 series of 25–45 longer, barbellate bristles, mid apically attenuate, 90–95% length of inner, inner apically weakly to strongly clavate [(0.5–in S. sphacelata) 1.5–5 (–7.3) mm].
