Biennials; glandular (at least distally); finely pubescent, often canescent, trichomes dendritic, sometimes mixed with simple ones. Stems erect, unbranched basally, branched distally, 4.5–13 dm. Basal leaves: petiole 1–3 cm; blade pinnate, oblanceolate to obovate or ovate in outline, 2–10 cm, lateral lobes (2–5 pairs), oblanceolate to lanceolate, (4–12 × 1–5 mm),margins entire or serrate to crenate, (apex obtuse). Cauline leaves sessile or shortly petiolate; blade smaller distally, distal lobes often narrower, surfaces densely pubescent. Racemes considerably elongated in fruit. Fruiting pedicels divaricate, straight, 13–31 mm. Flowers: sepals ascending, greenish to yellowish, oblong, 2–2.9 mm, pubescent, (trichomes dendritic, mixed with glandular papillae); petals oblanceolate, 1.8–2.6 × 0.5–0.7mm; median filaments 1.8–2.4 mm; anthers 0.3–0.5 mm. Fruits divaricate to erect, linear, slightly torulose, 8–16(–20) × 1–1.3 mm, (abruptly acute at both ends); valves each with distinct midvein, (sparsely pubescent or glabrescent); septum not veined; ovules 48–64 per ovary; style 0.1–0.2 mm, glabrous. Seeds biseriate, light brown, ellipsoid, 0.9–1.1 × 0.5–0.6 mm. 2n = 42.
