Heads discoid; involucres hemispheric, 6–11 mm high; phyllaries 5–13, lanceolate to oblong, tomentose, in 2–3 unequal series, membranous-margined; receptacle flat, naked. Disk flowers perfect, yellow, 2–4 mm long, glandular; tubes ca. as long as the dilated throat; style branch appendages hairy. Pappus of several short, hyaline scales.
