Leaves cauline; alternate; sessile; blades spatulate or oblanceolate to lance-linear, bases ± cuneate, margins entire (usually revolute), faces bicolor, abaxial gray, tomentose, adaxial green, glabrous. Heads disciform, usually in ± capitate to loose, spiciform arrays, rarely borne singly (in leaf axils). Involucres narrowly ovoid or nearly cylindric [campanulate or broadly turbinate], 8–11 mm. Phyllaries in 3–5+ series, usually greenish to stramineous, sometimes purplish (hyaline, stereomes not glandular), unequal, chartaceous toward tips. Receptacles flat, smooth, epaleate. Peripheral (pistillate) florets 10–25 (more numerous than bisexual); corollas whitish to purplish. Inner (bisexual) florets 3–5; corollas white to purplish. Cypselae obovoid, ± compressed (2–3-nerved), faces silvery sericeous (hairs not myxogenic); pappi persistent, of 20–30+, distinct or basally connate, ± plumose bristles in 1 series. x = 14.
