     Plants long-lived perennials, with woody caudices, lacking crowded, persistent leaf bases; sexual, with ellipsoid pollen. Stems usually 1 per caudex branch, elevated above ground surface on woody bases, arising from center of leaf tufts, (1.5–)3.0–7.5 dm, lower parts with abundant, short-stalked, mostly 4–7-rayed trichomes 0.1–0.3 mm, upper parts similarly pubescent. Leaves at stem bases linear to linear-oblanceolate, 1–3 mm wide, entire, not ciliate, blade surfaces densely pubescent with short-stalked, 4–9-rayed trichomes 0.1–0.3 mm; cauline leaves 10–30, often concealing stem proximally, the uppermost pubescent, lacking auricles or (rarely) with auricles to 0.5 mm. Inflorescences mostly unbranched, 8–25-flowered; fruiting pedicels 8–16 mm, reflexed, abruptly recurved at base but otherwise straight, with appressed, branched trichomes. Flowers descending at anthesis; sepals pubescent; petals purple (very rarely white), 9–16 ´ 2–4(–5) mm, with scattered trichomes abaxially or glabrous; ovules 68–106 per fruit. Fruits 3.3–8.0 cm ´ 2.5–4.0 mm, strongly reflexed, often appressed to rachises, occasionally somewhat secund, straight, with parallel edges, pubescent throughout; style 0.1–0.3 mm. Seeds biseriate, 1.7–2.8 ´ 1.5–2.2 mm; wing continuous, 0.25–0.65 mm wide.

Flowering: Mar–Jun.

Habitat: rocky, gravelly or sandy slopes in chaparral, sagebrush and desert scrub communities. Elevation: 850–2750 m.

Distribution: Mexico (Baja California), United States (California, Nevada).
