Leaves mostly basal or basal (persistent, persistent portion relatively long and slender-fibrous) and cauline (greenish); basal blades 1-nerved linear to linear-oblanceolate or oblanceolate or narrowly spatulate, (20–)30–80 × (0.5–)1–3 mm, cauline reduced distally (bases attenuate, not thickened and whitish-indurate) margins entire (apices obtuse or rounded), faces abaxially glabrous or glabrate, adaxially sparsely strigose, eglandular. Heads 1(–3 rarely, from branches at midstem). Involucres (3.5–)4-–6.5 × (5–)6–13 mm. Phyllaries in 2–4 series (greenish or sometimes purple, margins thickened), strigose to loosely strigoso-hirsute, sometimes more densely so on distal 1/3, sparsely minutely glandular.
