     Plants mostly long-lived perennials, often with woody caudices, lacking crowded, persistent leaf bases; sexual, with ellipsoid pollen. Stems usually 1 per caudex branch, arising near ground surface from center of basal rosettes, 0.9–3.0 dm, lower parts with abundant, short-stalked, 5–12-rayed trichomes 0.1–0.3 mm, upper parts sparsely pubescent to glabrescent. Leaves at stem bases linear-oblanceolate, 2–5 mm wide, entire, not ciliate, blade surfaces densely pubescent with short-stalked, 5–12(–16)-rayed trichomes 0.1–0.3 mm; cauline leaves 1–5, not concealing stem, the uppermost pubescent, without auricles. Inflorescences unbranched, 4–15(–20)-flowered; fruiting pedicels 4–15(–25) mm, ascending, straight, with appressed, branched trichomes. Flowers ascending at anthesis; sepals pubescent; petals purple to lavender, 5–6 ´ 1.0–1.5 mm, glabrous; ovules 44–52 per fruit. Fruits 4.0–7.3 cm ´ 2.7–4.0 mm, divaricate-ascending, not appressed to rachises, not secund, straight, with parallel edges, glabrous; style 0.05–0.10 mm. Seeds uniseriate, 1.9–2.3 mm in diam.; wing continuous, 0.3–0.5 mm wide.
