Information

Annuals or biennials; usually sparsely to densely hirsute proximally, rarely glabrous throughout. Stems erect, unbranched or branched basally, branched distally, 2–8 dm. Basal leaves: petiole (1–)2–6(–8) cm; blade spatulate to obovate in outline, lyrate, pinnatifid, or bipinnately lobed, (2–)4–20(–25) cm × 30–80 mm, surfaces glabrous or hirsute. Cauline leaves shortly petiolate or sessile; blade base not auriculate, similar to basal, smaller distally. Racemes lax or dense. Fruiting pedicels divaricate-ascending, 5–15(–20) mm, glabrous or pubescent. Flowers: sepals (2.5–)3.5–4.5(–5) × 1.5–2 mm; petals white to purplish, spatulate, 6–9(–11) × 2.5–3.5(–4.5) mm, claw 2.5–4(–5) mm, margins pinnatifid, 5–7(–11)-lobed, papillate basally; filaments papillate basally, median pairs 3–5 mm, lateral pair 2.5–4 mm; anthers oblong, 0.7–1 mm. Fruits linear, (straight or arcuate), 2–6 cm × 0.5–1.2 mm; ovules 60–110 per ovary; style 0.1–0.7(–1) mm. Seeds 0.6–0.8 × 0.4–0.6 mm, not winged. 2n = 24.
