    (10–)100–1600 m
    Plants 10–70 cm, laxly cespitose (grayish green), eglandular;
    rhizomes elongate, slender, woody.
    Stems 1–3, ascending to erect, often purple, simple, flexuous, proximally glabrescent or sparsely villous, distally ± densely villous.
    Leaves cauline, firm, margins slightly revolute, coarsely serrate or (distal) entire, scabrous to strigoso-ciliate, teeth mucronate, ± markedly veined, apices mucronate, abaxial faces scabrous, adaxial scabroso-strigose;
    proximal mostly withering by flowering, petioles winged, shorter than blades, bases clasping, blades elliptic to obovate 12–45+ × 7–20+ mm, smaller than mid, apices obtuse;
    mid narrowly winged-petiolate (petioles short with ± clasping bases), distally subpetiolate or sessile, blades ovate or elliptic to broadly oblanceolate or obovate, 32–85 (–130) × 4–40 mm, gradually reduced distally, bases usually attenuate, sometimes cuneate, apices obtuse to acute;
    distal (arrays) oblanceolate to lanceolate, 5–28 × 1–8 mm, more sharply reduced.
    Heads 5–30+ in flat-topped, corymbiform arrays.
    Peduncles densely villous;
    bracts 0–1, scabroso-strigose.
    Involucres campanulate, 6–9 mm, shorter than pappi.
    Phyllaries 38–62 in 4–5 series, midnerves slightly raised (outer), oblong (outer) to lanceolate-linear or linear (inner), unequal, membranous, bases indurate, ± rounded, green zones to scarious margins in distal 1/3–1/2 (outer; seldom ± wholly foliaceous) to 1/5 or none (inner), margins often purple, hyaline, narrowly scarious, erose, densely villoso-ciliate, apices appressed, sometimes purplish-tinged, usually acute, sometimes obtuse, adaxial faces villous.
    Ray-florets 10–15;
    corollas white to sometimes pale violet or purple, 8.5–11 (–13) × 1.3–2.3 mm.
    Disc-florets 30–70;
    corollas yellow becoming purple or pinkish-tinged, 6–7 (–8) mm, ± ampliate, tubes equaling to longer than funnelform-campanulate throats, lobes usually erect, sometimes ± spreading, lanceolate, 1–1.3 mm.
    Cypselae tawny, fusiform, 3–3.5 mm, slightly compressed, ribs 7–9 (brown, translucent), faces strigillose;
    pappi of tawny bristles 2.7–3 mm, ± equaling disc corollas.
