     Plants mostly long-lived perennials, often with woody caudices, lacking crowded, persistent leaf bases; apomictic, with spheroid pollen. Stems usually 1 per caudex branch, arising near ground surface from center of basal rosettes, 1.5–4.5 dm, lower parts with abundant, short-stalked, 4–9-rayed trichomes 0.05–0.20 mm, upper parts glabrous or sparsely pubescent. Leaves at stem bases linear to narrowly oblanceolate, 1–4 mm wide, entire, ciliate at petiole base with simple trichomes to 0.5 mm, blade surfaces densely pubescent with short-stalked, 4–9-rayed trichomes 0.05–0.20 mm; cauline leaves 5–9, not concealing stem, the uppermost sparsely pubescent, with auricles 0.5–1.0 mm. Inflorescences sparingly branched, 10–18-flowered; fruiting pedicels 6–12 mm, divaricate-descending, gently curved downward, with appressed, branched trichomes. Flowers divaricate-ascending at anthesis; sepals pubescent; petals lavender, 5–7 ´ 0.7–1.2 mm, glabrous; ovules 62–80 per fruit. Fruits 4.5–6.0 cm ´ 1.2–1.5 mm, divaricate-descending, not appressed to rachises, not secund, gently curved, with parallel edges, glabrous; style 0.5–1.0 mm. Seeds uniseriate, 1.2–1.7 ´ 0.8–1.2 mm; wing mostly distal, 0.05–0.10 mm wide.
