Plants short-lived perennials to biennials, with or without caudices, lacking crowded, persistent leaf bases; apomictic, with spheroid pollen. Stems usually 1 per caudex branch, arising near ground surface from center of basal rosettes, 2.6–7.4(–10.2) dm, lower parts with abundant, short-stalked, 4–8-rayed trichomes 0.1–0.5 mm, these sometimes mixed with 2- or 3-rayed trichomes to 1 mm, upper parts sparsely pubescent or rarely glabrous. Leaves at stem bases oblanceolate, 3–8(–10) mm wide, entire or shallowly dentate, ciliate near petiole bases with simple trichomes to 1 mm, blade surfaces moderately to densely pubescent with short-stalked, 4–8-rayed trichomes 0.15–0.4 mm; cauline leaves 22–72, concealing stem proximally, the uppermost sparsely pubescent or glabrous, with auricles 1–4 mm. Inflorescences mostly unbranched, 25–112-flowered; fruiting pedicels (10–)15–28 mm, divaricate-descending, straight or gently curved, with a few appressed, branched trichomes or rarely glabrous. Flowers divaricate-ascending at anthesis; sepals pubescent; petals white to lavender, 6–8 ´ 1.0–1.5 mm, glabrous; ovules 100–136 per fruit. Fruits 4.5–6.5 cm ´ 1.5–2.9 mm, pendent, not appressed to rachises, not secund, straight or gently curved, with parallel edges, glabrous; style to 0.2 mm. Seeds biseriate or subbiseriate, 1.0–1.4 ´ 0.9–1.0; wing continuous, 0.05–0.15 mm.
