Leaves basal (basal mostly withered or deciduous before flowering, not forming conspicuous tufts) and cauline (leaf bases broadened or not, not thickened and whitish-indurate); blades linear to linear-oblanceolate, 30–60 × 1–4 mm, cauline abruptly reduced distally, margins entire, faces silvery-strigose, eglandular. Heads 1–5(–10). Involucres 5–7 × 10–15 mm. Phyllaries in 3–4 series, glabrous or sparsely strigose proximally, minutely glandular. Ray florets 30–55; corollas white or pink, 6–13 mm, laminae reflexing. Disc corollas 3.5–5 mm.
