     Plants short- to long-lived perennials, with mostly non-woody caudices, lacking crowded, persistent leaf bases; sexual, with ellipsoid pollen. Stems usually 2–6 per caudex branch, arising near ground surface from margin of basal rosettes, 0.8–4 dm, lower parts with abundant, simple and short-stalked, 2-rayed trichomes 0.3–0.6 mm, upper parts glabrous. Leaves at stem bases narrowly oblanceolate, 1–5 mm wide, entire or few toothed, ciliate proximally with simple trichomes to 0.9 mm, blade surfaces densely pubescent with simple and short-stalked, 2- or 3-rayed trichomes 0.3–0.5 mm; cauline leaves 3–6, not concealing stem, the uppermost glabrous, with auricles 0.3–0.6 mm. Inflorescences mostly unbranched, 7–15-flowered; fruiting pedicels 4–10 mm, divaricate-ascending to horizontal, straight or gently recurved, glabrous or with few, spreading trichomes. Flowers ascending at anthesis; sepals pubescent; petals lavender, 3.5–6.0 ´ 1.0–1.5 mm, glabrous; ovules 50–80 per fruit. Fruits 2.5–4.0 cm ´ 1.2–1.5 mm, divaricate-ascending to horizontal, not appressed to rachises, not secund, usually curved, with parallel edges, glabrous; style 0.05–0.30 mm. Seeds uniseriate, 1.0–1.5 ´ 0.7–1.0 mm; wing usually distal, ca. 0.1 mm wide.
