Stems 3 to many per caudex branch, arising near ground surface from margin of basal rosettes, 3.5–6.0 dm, lower parts with short-stalked, 2–4-rayed trichomes 0.2–0.3 mm, upper parts glabrous. Leaves at stem bases oblanceolate, 3–7 mm wide, dentate, ciliate proximally with simple trichomes to 0.3 mm, blade surfaces pubescent with short-stalked, 4–8-rayed trichomes 0.05–0.2 mm; cauline leaves 5–10, not concealing stem, the uppermost glabrous, with auricles 0.5–1 mm. Inflorescences mostly unbranched, 10–18-flowered; fruiting pedicels 5–10 mm, divaricate-descending, straight, glabrous.
