Herbage usually glabrous or sparsely hispidulous, sometimes densely hirtellous, leaves sometimes stipitate-glandular, never resinous. Leaf blades oblanceolate to narrowly oblong-oblanceolate or nearly linear, mostly 10–40(–50) mm, margins usually entire (hispidulous-cilate, sometimes also on faces), sometimes shallowly toothed distally (especially along western margin of range; teeth in 1(–3) pairs). Involucres 3.2–5.5 × 2.5–4 mm. Phyllary apices yellowish, or if green, then margins scarious, not aristate, gland-dotted, without resin pockets. Florets (8–)11–17(–21); corollas 5–6 mm. Cypsela ribs not forming hornlike extensions. 2n = 12, 24.
