Leaves basal and cauline; cauline leaves gradually or sometimes abruptly reduced upward, both surfaces scabridulous or hirsute, margin ciliate, 3-veined, veins conspicuous; basal leaves winged petiolate, petiole base subclasping; blade spatulate or obovate to oblanceolate, 0.5-5 × 0.3-2 cm, base attenuate, margin entire or remotely serrulate in upper half, apex obtuse to rounded, sometimes acute; lower cauline leaves sessile, oblong to linear-lanceolate, base subclasping; middle and upper cauline leaves 1-5 × 0.1-0.7 cm, apex acute. Capitula terminal, solitary (rarely 2), 3-5(-6.5) cm in diam. Involucres hemispheric, 5-7 mm; phyllaries 2-or 3-seriate, subequal, appressed or often squarrose, oblong-linear, 5-8 × 0.8-1.5 mm, abaxially villosulous, hardened below, leaflike above, apex acute.

Achenes broadly obovoid, ca. 2 mm, densely strigillose, 2-ribbbed (ribs sparsely strigillose, densely so apically). Pappus 4-seriate, purple-brown to brown, of few bristles; outermost bristles slender, 0.2-0.7 mm; outer bristles slender, 0.7-1 mm; inner bristles 1.2-1.6 mm, acute; innermost bristles 1.5-2 mm, slightly to distinctly clavate.
