Basal leaves (withered by flowering); similar to cauline. Cauline leaves: petiole 0.7-6.2 cm; blade (fleshy), oblanceolate to broadly lanceolate or ovate in outline, or (distally) lobed or linear to narrowly lanceolate, 3-15 cm (smaller distally), margins lyrate-pinnatifid or runcinate, or (distal) pinnately lobed or entire. Racemes somewhat dense. Fruiting pedicels horizontal to divaricate, 3-11 mm. Flowers: sepals oblong-linear, 8-16 mm; petals yellow, oblanceolate to oblong, 8-20 × 2-3 mm, claw 4-10 mm, wider at base, densely pubescent inside; filaments 11-28 mm, pilose at base; anthers 3-5 mm; gynophore 7-28 mm. Fruits usually spreading to divaricate, rarely ascending, often strongly curved downward, not tortuous, (smooth), terete, 3-9 cm × 1.5-3 mm; ovules 10-38 per ovary; style 0.2-0.6 mm.
