Basal leaves usually rosulate; petiole (1–)2–7(–10) cm; blade broadly oblanceolate or oblong-obovate (in outline), (2–)3–10(–15) cm × (10–)20–50(–80) mm, margins lyrate-pinnatifid, pinnatisect, or runcinate; lobes (2)3 or 4(5) on each side, oblong or lanceolate, smaller than terminal lobe, margins entire, dentate, or lobed, (terminal lobe suborbicular or deltate, margins dentate). Cauline leaves similar to basal; blade with lobe margins dentate or subentire. Fruiting pedicels erect, (appressed to rachis), stout, narrower than fruit, 1.5–3(–4) mm. Flowers: sepals erect, oblong-ovate, 2–2.5 × ca. 1 mm; petals spatulate, 2.5–4 × 1–2 mm, claw 1–2 mm; filaments (erect, yellowish), 2–3 mm; anthers ovate, 0.3–0.5 mm. Fruits (erect), subulate-linear, straight, slightly torulose or smooth, stout, (0.7–)1–1.4(–1.8) cm × 1–1.5 mm; valves glabrous or pubescent; ovules 10–20 per ovary; style (0.8–)1–1.5(–2) mm; stigma slightly 2-lobed. Seeds 1–1.3 × 0.5–0.6 mm. 2n = 14.
