Perennials; caudex simple, (relatively large); densely (silvery) pubescent, trichomes (sessile, appressed), rays furcate, fused at base. Stems simple from base, decumbent to nearly prostrate, 0.5–1.3 dm. Basal leaves (strongly rosulate; shortly petiolate); blade broadly obovate, 1.5–7.5 (width 7.5–26 mm, base gradually tapering to petiole), margins shallowly dentate, (apex obtuse). Cauline leaves: blade oblanceolate to broadly obovate, 1–2.5 cm, margins entire. Racemes dense. Fruiting pedicels (divaricate-ascending to widely spreading, slightly sigmoid to curved), 7–12 mm. Flowers: sepals (pale yellow or yellow-green), narrowly lanceolate to narrowly deltate, 4–8 mm; petals yellow, broadly spatulate to obovate, 9–13 mm, (not clawed). Fruits didymous, slightly flattened (contrary to replum) to uncompressed, 4–9 × 2–8 mm, (strongly coriaceous, apical and basal sinuses narrow, deep); valves (retaining seeds after dehiscence), pubescent, trichomes appressed; replum narrowly oblanceolate to narrowly linear-oblong, as wide as or wider than fruit, apex obtuse; ovules 4 per ovary; style more than 3 mm. Seeds compressed. 2n = 8.
Phenology: Flowering Mar–Jun(-Jul).
Habitat: Dark shale, road cuts, ridge crests, washes
Elevation: 1500-1800 m
