Stems simple or few from caudex, erect, branched (several) distally, (1.5–)2.5–5.5(–6.5) dm, densely pubescent throughout. Basal leaves often rosulate; petiole (1–)2–5(–7) cm; blade spatulate to linear-oblanceolate, (1–)1.7–5 cm × (3–)4–9(–12) mm, margins entire or dentate, surfaces densely pubescent. Cauline leaves 3–7 (widely spaced); blade linear-oblanceolate, 2–7 cm × 1–5(–8) mm, margins usually entire, rarely minutely sparsely denticulate, apex obtuse, surfaces densely pubescent. Fruiting pedicels (5–)8–14(–17) mm, densely pubescent. Flowers: sepals 2.5–3 × 1–1.5 mm; petals (4–)5–6.5(–7.5) × (1.2–)1.5–2(–2.2) mm; filaments 1.5–3 mm; anthers oblong, 0.6–0.8 mm. Fruits suberect, (not appressed to rachis), straight, slightly torulose, subterete, (1–)1.3–1.8(–2) cm × 0.8–1 mm; valves each with obscure midvein on proximal 1/2, densely pubescent; ovules 20–30 per ovary; style 0.2–0.4 mm.
