Fruiting pedicels suberect, appressed to rachis, or ascending, straight, 1.5-4(-6) mm, terete or slightly flattened, glabrous. Sepals oblong, 1-1.8 × 0.5-0.8 mm, glabrous or pubescent abaxially. Petals white or lavender, spatulate or obovate, 2.5-3.5(-4) × 0.7-1.4 mm, base attenuate. Stamens 6; filaments 1.5-2 mm; anthers oblong, 0.4-0.5 mm. Fruit oblong-ovate or elliptic, (4-)5-6(-7) × 3-4.5(-5.5) mm, base rounded, margin and apex broadly winged, apex emarginate; wings 1-1.5 mm at apex; apical notch 0.2-0.5 mm; style 0.2-0.5(-0.8) mm, free from wings, included in or rarely exserted from apical notch.

Annual. Stem erect, glabrous, (10)-20-40-(90) cm tall. Basal lvs withering at flowering, glabrous or sparsely hairy, 3-10-(20) × 1-4-(8) cm, 1-2-pinnatifid with slender toothed lobes. Middle stem lvs deeply 1-2-pinnatisect with linear-obovate lobes; uppermost lvs sparsely hairy, 1-pinnatifid, becoming linear-obovate, entire, 2-4 × 0.3-0.5 cm. Racemes 10-25 cm long; pedicels 4-6 mm at fruiting. Sepals sparsely hairy, 1-1.5 × 0.4-0.6 mm. Petals twice as long as sepals, white or reddish. Stamens 6. Silicle elliptic, narrowly winged above, 5-6 × 3-5 mm; style not projecting beyond deep apical notch; valves glabrous. Seeds narrowly ovoid, red-brown, not winged, up to 5 mm long; cotyledons deeply 3-lobed.
Annual herb; stems erect, unbranched, 20–40 cm high, glabrous. Basal leaves bi-to tri-pinnatisect; cauline leaves reducing to linear, entire, sessile, sparsely hairy, the hairs acicular. Inflorescence an elongating raceme. Sepals 1–1.5 mm long, sparsely hairy. Petals 2–3 mm long, somewhat clawed, white or reddish. Stamens 6. Style to 0.5 mm long, included. Silicula broadly ovate, 5–6 mm long, 3–5 mm wide, glabrous; wing narrow above, one-fifth length of silicula; pedicels 3–5 mm long, ascending to erect.

A cabbage family herb. It is an annual plant about 60 cm high. It has narrowly lobed leaves. The leaves near the base have long stalks and the leaves higher on the plant do not have stalks. The flowers are small and white. The fruit is a pod. These are oval and deeply notched. The seed pods are reddish brown. The plant develops tuberous roots and grow for a second season. There are some named cultivated varieties.
. Glabrous, ± glaucous annual 2–4 dm; lvs pinnately dissected into a few linear, oblong, or oblanceolate segments; fls 2 mm wide; stamens 6; fr elliptic-oval, 5–7 mm, two-thirds as wide, deeply notched; style half as long to nearly as long as the notch; mature pedicels erect or closely ascending, 2–4 mm; 2n=16, 24. Native probably of w. Asia, escaped from cult. especially in the ne. part of our range.
