Perennials. Stems erect to ascending, often paniculately branched distally, (1.2–)3–7.5(–12) dm, trichomes sessile or subsessile. Basal leaves absent on older plants. Cauline leaves petiolate or (distal) sessile; petiole 0.5–1 cm; blade oblanceolate, lanceolate to oblong, or elliptic, (1–)2–5.5(–7) cm × (4–)7–20(–30) mm (smaller distally), base cuneate, margins sinuately lobed or dentate, surfaces with minutely stalked to subsessile trichomes. Racemes slightly to considerably elongated in fruit. Fruiting pedicels usually divaricate, rarely slightly descending, (2–)3–6(–9) mm. Flowers: sepals slightly spreading, 1.2–2 × 0.4–0.7 mm; petals (slightly spreading), spatulate, (slender), 1.8–2.5 × 0.7–1 mm, claw distinctly differentiated from blade, 0.5–1 mm; filaments spreading, 2.2–3 mm, longer than petals; anthers 0.3–0.5 mm. Fruits divaricate or slightly descending, straight, subtorulose, linear, terete, 0.6–1.4(–1.7) cm × 0.5–0.8 mm; ovules 16–24 per ovary; style 0.7–1(–1.5) mm. Seeds uniseriate, 0.8–1 × 0.4–0.6 mm.
