     Plants long-lived perennials, with woody caudices, occasionally with crowded, persistent leaf bases; sexual, with ellipsoid pollen. Stems usually 1 per caudex branch, often elevated above ground surface on woody base, arising from center of basal rosettes, 5–7 dm, lower parts glabrous or with few short-stalked, 2–3-rayed trichomes 0.15–0.40 mm, upper parts glabrous to sparsely pubescent. Leaves at stem narrowly oblanceolate, 3–8 mm wide, coarsely dentate, ciliate with simple and 2-rayed trichomes to 0.6 mm, blade surfaces sparsely to densely pubescent with short-stalked, 2–7-rayed trichomes 0.15–0.40 mm; cauline leaves 15–65, concealing stem, the uppermost pubescent, with auricles 1–4 mm. Inflorescences occasionally branched, 30–70-flowered; fruiting pedicels 10–45 mm, divaricate-ascending, straight, glabrous. Flowers ascending at anthesis; sepals pubescent; petals white or pale lavender, 8–10 ´ 1.5–2.0 mm, glabrous; ovules 170–220 per fruit. Fruits 6–10 cm ´ 2.5–3.0 mm, divaricate-ascending to horizontal, not appressed to rachises, not secund, curved or rarely straight, with parallel edges, glabrous; style 0.05–0.50 mm. Seeds biseriate, 1.2–1.6 ´ 0.9–1.2 mm; wing continuous, 0.1–0.2 mm wide.
