Stems usually 1 per caudex branch, arising near ground surface from center of basal rosettes, 2–6 dm, lower glabrous or sparsely with simple and stalked, 2-rayed trichomes 0.3–0.8 mm, upper parts glabrous. Leaves at stem bases oblanceolate to oblon, 2–8 mm wide, coarsely dentate, ciliate along petiole with trichomes to 0.4–0.8 mm, blade surfaces pubescent with stalked, 4–9-rayed trichomes 0.2–0.4 mm; cauline leaves 6–14, not concealing stem, entire, the uppermost glabrous or sparsely pubescent, with auricles 0.5–1.5 mm. Inflorescences unbranched; fruiting pedicels 1–3 cm, divaricate-ascending, straight, glabrous. Flowers ascending at anthesis; sepals subapically pubescent; petals lavender to purplish, 7–10 ´ 1.75–2.5 mm, glabrous. Fruits 4.5–6 cm ´ 2–3 mm, divaricate-ascending, not appressed to rachises, not secund, usually strongly curved, with parallel edges, glabrous; style 0.2–0.6 mm. Seeds uniseriate, suborbicular, to 2 mm diam.; wing continuous. 2n = 14.
