Perennials; (caudex usually simple, rarely branched, covered with persistent petiolar remains); sparsely to densely pubescent, trichomes short-stalked, cruci-form, or 3-rayed stellate, (0.3–0.5 mm). Stems simple or few from base (caudex), erect, usually unbranched, rarely branched (few) distally, 2.2–5.5(–6.7) dm, (usually pubescent throughout, rarely subglabrate distally, trichomes stellate). Basal leaves: petiole 1–4(–5) cm, (rarely minutely ciliate near base); blade oblanceolate to obovate, (0.8–)2–4.5(–6) cm × (4–)10–20(–25) mm, margins entire, repand, or dentate, (not ciliate), apex obtuse, surfaces pubescent, trichomes short-stalked, stellate. Cauline leaves (2–)4–6(–9); blade oblong or ovate, 1–3.5(–4.5) cm × (3–)6–10(–20) mm, base not auriculate, margins entire, repand, or dentate, apex obtuse or acute, surfaces pubescent, trichomes short-stalked, stellate. Racemes simple, (dense). Fruiting pedicels ascending to divaricate, 7–18(–25) mm. Flowers: sepals (purple), oblong, (4–)5–6.5(–8) × 1.5–2 mm, lateral pair saccate basally; petals purple, spatulate, (10–)12–16(–20) × 4–6(–7) mm, apex rounded; filaments (4–)5–8 mm; anthers narrowly oblong, 1.3–2 mm. Fruits suberect to divaricate, sometimes slightly curved, slightly torulose, (2.8–)3.5–6 cm × 1.5–2 mm; valves each with prominent midvein extending to middle or full length; ovules 20–34 per ovary; style 0.5–1(–1.5) mm. Seeds winged distally, oblong, 1.7–2.2 × 0.9–1.2 mm; wing 0.2–0.5 mm wide. 2n = 32.
