     Plants biennials or short-lived perennials, with or without 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, 2–8(–10) dm, lower parts glabrous or rarely with few simple trichomes to 0.7 mm, upper parts glabrous. Leaves at stem bases oblanceolate, 3–8(–13) mm wide, entire or denticulate, ciliate with simple trichomes 0.5–1.2 mm, blade surfaces sparsely to densely pubescent with simple trichomes to 0.8 mm, these often mixed with short-stalked, 2–3-rayed trichomes 0.15–0.5 mm; cauline leaves 6–30(–45), often concealing stem proximally, the uppermost ciliate or sparsely pubescent, with auricles 1–1.5 mm. Inflorescences mostly unbranched, 10–30(–50)-flowered; fruiting pedicels 4–10 mm, reflexed, abruptly recurved at base but otherwise straight, glabrous. Flowers pendent at anthesis; sepals pubescent; petals white, 3–4 ´ 0.7–1.2 mm, glabrous; ovules 46–80 per fruit. Fruits 5–9 cm ´ 1.8–2.5 mm, strongly reflexed, usually appressed to rachises, not secund, straight, with parallel edges, glabrous; style 0.2–0.8 mm. Seeds uniseriate, 1.8–2.1 ´ 1.0–1.5 mm; wing continuous, 0.15–0.25 mm wide.
