     Plants short- to long-lived perennials, with mostly non-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, (0.6–)1.0–4.5 dm, lower parts with abundant, short-stalked, 4–8-rayed trichomes 0.1–0.4 mm, uppar parts similarly pubescent. Leaves at stem bases linear to linear-oblanceolate, 2–4(–6) mm wide, entire, usually ciliate at petiole base with simple or spurred trichomes to 1.5 mm, blade surfaces densely pubescent with short-stalked, 4–8-rayed trichomes 0.1–0.4 mm; cauline leaves 6–10, not concealing stem, the uppermost densely pubescent, lacking auricles. Inflorescences mostly unbranched, (5–)10–25-flowered; fruiting pedicels 2–10 mm, reflexed, strongly curved at the base, with appressed, branched trichomes. Flowers divaricate at anthesis; sepals pubescent; petals light purple to lavender, 6–9 ´ 1.5–2.5 mm, glabrous; ovules 24–62 per fruit. Fruits (1.8–)2.5–4.5 cm ´ 5–8 mm, strongly reflexed, occasionally appressed to rachises, often secund, straight, with parallel edges, glabrous; style 0.2–0.6 mm. Seeds biseriate, 5–6 ´ 4–5 mm; wing continuous, 1.8–2.5 mm wide. 2n = 14.

Flowering: Mar­­-Apr.

Habitat: rocky slopes and gravelly soil, usually under shelter of desert shrubs.
