    with thick, woody, branched caudices, or short, fleshy rhizomes, sometimes with woody cormoid portions.
    Stems 1–5+, erect (stout, light to dark-brown, sometimes purplish distally), proximally sparsely to moderately hispiduloso-hirsute or pilose, distally moderately to densely so, stipitate-glandular.
    Leaves (light to dark green) thin, often stiff, margins entire or sometimes with shallow teeth, ciliate;
    basal withered or withering by flowering, sessile, blades (3-nerved) usually spatulate, sometimes oblanceolate, 20–60 × 5–15 mm, bases attenuate, apices acute, faces sparsely hirsute;
    proximal cauline withering by flowering, sessile, blades oblong or lanceolate, 50–100 × 5–15 (–20) mm, bases auriculate-clasping, margins entire, pustulate-scabrous, apices acute, mucronulate, faces stipitate-glandular, abaxial thinly strigose, adaxial hirsute or hispidulous;
    distal sessile, blades oblanceolate, 30–80 × 6–15 mm, gradually reduced distally, bases auriculate-clasping, apices acute to obtuse, mucronate to minutely white-spinulose, faces moderately to densely short-soft-hairy, sparsely to moderately stipitate-glandular.
    Heads in leafy, often crowded, paniculo-corymbiform arrays.
    Peduncles dilated distally, 0.3–4 cm, densely short-hairy, stipitate-glandular, bracts 1–4, foliaceous, linear to narrowly lanceolate, densely short-hairy, stipitate-glandular, grading into phyllaries.
    Involucres campanulate to hemispheric, (5–) 7–9 (–15) mm.
    Phyllaries in 3–5 (–6) series (dark green to purple-tinged), linear-lanceolate, subequal, outer foliaceous, mid and inner scarious in basal 1/3–1/2, margins stipitate-glandular, apices long-acuminate to acuminate, spreading to reflexed or squarrose, faces glabrous, outer densely stipitate-glandular.
