Basal leaves: petiole 0.4–4.2 cm; blade pinnate, oblanceolate to obovate in outline, 1.5–6 cm, lateral lobes [2–4 (or 5) pairs], lanceolate, (5–22 × 1–5 mm), margins usually entire or crenate to incised, rarely lobed. Cauline leaves sessile or shortly petiolate; blade smaller distally, distal lobes often narrower, surfaces sparsely pubescent. Racemes considerably elongated in fruit. Fruiting pedicels divaricate to ascending or suberect, often straight, 3–9(–11) mm.

Fruits divaricate to erect, fusiform, not torulose, (2–)3–5(–6) × (0.8–)1–1.3 mm, (long-acute at both ends); valves each with obscure midvein; septum not veined; ovules 4–12 per ovary; style (0.2–)0.3–0.6(–0.8) mm, glabrous.
