Leaves basal and cauline, cauline leaves reduced upward, densely to moderately strigose, sometimes upper leaves glandular, midvein abaxially somewhat prominent, triplinerved, veins inconspicuous; basal leaves usually persistent, broadly winged petiolate; blade spatulate to oblanceolate, ca. 2.5 × 0.6-1 cm, base attenuate, margin entire or sparsely serrulate, densely strigose-ciliate, apex obtuse or rounded; middle leaves oblong to oblanceolate, 2-3.5 × 0.4-0.7 cm, base subclasping; upper leaves small, apex acute. Capitula terminal, solitary, 4-5 cm in diam. Involucres hemispheric, 0.6-0.7 × 1.5-1.7(-2) cm; phyllaries 3-seriate, spatulate-oblong to oblong or linear, 9-10 × 1.5-2.5 mm, abaxially sparsely strigose, leaflike, margin strigose-ciliate, inner phyllaries with margin scarious, erose-fimbriate, purplish, apex acute or obtuse, purplish.
