     Plants long-lived perennial, 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 tuft, 2–4.2 dm, lower parts with abundant short-stalked, 3–6-rayed trichomes 0.1–0.5 mm, upper parts similarly pubescent. Leaves at stem bases linear or linear-oblanceolate, 1–2 mm wide, entire, rarely ciliate near petiole bases with simple trichomes to 1 mm, blade surfaces densely pubescent with short-stalked, 3–8-rayed trichomes 0.1–0.4 mm; cauline leaves 10–25, concealing stem proximally, the uppermost densely pubescent, lacking auricles or (rarely) with auricles to 1 mm. Inflorescences mostly unbranched, 7–15-flowered; fruiting pedicels 10–20(–25) mm, divaricate-ascending, straight to slightly curved proximally, recurved distally, with appressed, branched trichomes. Flowers divaricate-ascending at anthesis; sepals pubescent; petals lavender to purple, 10–12 ´ 2–3 mm, occasionally with few trichomes abaxially; ovules 86–120 per fruit. Fruits (3.2–)4.0–5.5 cm ´ 2.0–2.5 mm, widely pendent, not appressed to rachises, not secund, straight, with parallel edges, pubescent throughout; style 0.1–0.3 mm. Seeds biseriate, 1.0–1.5 ´ 0.7–0.9 mm; wing continuous, 0.07–0.12 mm wide. 2n = 14.
