Stems 1–3 per caudex branch, arising near ground surface from margin of basal rosettes, 0.4–1.6 dm, lower parts with abundant short-stalked, 2–5-rayed trichomes 0.05–0.2 mm, upper parts glabrous or sparsely pubescent. Leaves at stem bases linear-oblanceolate, 1–3 mm wide, entire, rarely ciliate proximally with trichomes to 0.5 mm, blade surfaces densely pubescent with short-stalked, 2–5-rayed trichomes 0.05–0.2 mm; cauline leaves 3–6, not concealing stem, the uppermost sparsely to moderately pubescent, without auricles or (rarely) to 0.3 mm. Inflorescences unbranched, 5–8-flowered; fruiting pedicels 2–6 mm, ascending to divaricate-ascending, straight, glabrous or with few appressed, branched trichomes.
