Stems simple or several from base, 2–12.3 dm, pubescent proximally, trichomes predominantly dendritic, mixed with simple and long-stalked, 2-rayed ones, glabrous or sparsely pubescent distally, trichomes dendritic. Basal leaves caducous; petiole 0.5–4 cm; blade oblanceolate, (1–)3–5 cm × 6–34 mm, margins sinuate, lobed, dentate, or, rarely, subentire, surfaces pubescent, trichomes dendritic. Cauline leaves (distal) subsessile; blade oblanceolate, 3–10 cm × 1–20 mm, surfaces glabrous or glabrate. Racemes not secund, 1.5–6.7 dm in fruit. Fruiting pedicels slightly erect to divaricate-ascending, straight, (3–)3.5–8.5(–11) mm. Flowers: sepals purple or green, broadly oblong, 2.7–4 × 1.2–2 mm; petals purplish apically, spatulate to oblanceolate, 1.5–4(–5) × 0.5–2.2 mm; filaments 0.9–2.6mm; anthers 1–1.2 mm. Fruits erect to ascending, straight, (1.5–)2.2–5.8 cm × 0.6–1.8 mm, terete; valves glabrous or sparsely pubescent; septum transparent; ovules 90–140 per ovary; style obsolete to 0.5 mm.
