Perennials; caudex simple or branched, (covered with persistent leaf-bases, loosely cespitose); densely pubescent, trichomes (appressed to ascending, plant appearing shaggy, always appressed on fruits), 4-rayed or 5-rayed, rays furcate or bifurcate, (tuberculate throughout). Stems few to several from base, ± erect, (arising laterally, also from within basal leaves), 0.2–0.4 dm. Basal leaves (erect); blade linear-oblanceolate, 1.2–2.8 cm, (base gradually narrowed to petiole), margins entire. Cauline leaves: blade linear, similar to basal. Racemes dense, (often subumbellate, not or barely exceeding basal leaves). Fruiting pedicels (ascending, curved), 3–5.5 mm. Flowers: sepals (pale green-yellow), oblong to elliptic, 4–5 mm, (median pair usually thickened apically, cucullate); petals lingulate, 6–9 mm. Fruits lanceolate in outline, compressed (latiseptate) on margins and at apex, 4–5 mm; valves pubescent, trichomes closely appressed; ovules 8–12 per ovary; style 3.5–4.5 mm (equaling or exceeding length of fruit, curved proximal to stigma). Seeds plump, (oblong).


Phenology: Flowering May–Jul.
Habitat: Open areas of grasslands on calcareous soils
Elevation: 1200-1900 m
