Herbs annual, (12-)30-80(-100) cm tall, glabrous or sparsely pubescent with small branched trichomes rarely mixed with fewer simple ones. Stems simple or branched above, often glabrescent. Cauline leaves lanceolate, narrowly oblong, or linear-lanceolate, middle ones (1-)2-7(-9) cm × 2-10(-15) mm, glabrescent or sparsely pubescent with primarily forked trichomes, base sagittate or strongly auriculate, margin entire or rarely remotely denticulate, apex acute. Fruiting pedicels (0.8-)1.2-2(-2.7) cm. Sepals 2-3 × 0.5-1 mm. Petals yellow, (3-)4-5.5 × 0.5-1 mm. Filaments 1.5-3 mm; anthers ca. 0.5 mm. Fruit obpyriform or broadly obovoid, 7-9(-10) × 4-5 mm, often subtruncate at apex; valves with a distinct midvein and less prominent lateral veins; style 1-2.5 mm. Seeds dark brown, oblong (1.5-)1.7-2.5(-3) × 0.7-1 mm. Fl. May-Jun. 2n = 40*.
Annuals or biennials. Stems unbranched or branched distally, (1.2-)3-10(-13) dm, glabrous or sparsely pubescent basally, trichomes branched, rarely mixed with fewer, simple ones. Basal leaves often withered by anthesis. Cauline leaves: blade lanceolate, narrowly oblong, or linear-lanceolate, (1-)2-7(-9) cm × 2-10(-15) mm, base sagittate or strongly auriculate, margins entire or, rarely, remotely denticulate, apex acute, surfaces glabrescent or sparsely pubescent, trichomes usually forked. Fruiting pedicels ascending, (8-)12-20(-27) mm. Flowers: sepals 2-3(-4) × 0.5-1 mm; petals yellow, (3.5-)4-6 × 1-1.5 mm; filaments 1.5-3 mm; anthers ca. 0.5 mm. Fruits pyriform or broadly obovoid, 7-9 (-13) × 4-5(-6) mm (distinctly longer than wide), apex often subtruncate; valves each with prominent midvein, margin narrowly winged; style 1.2-2.5 mm. Seeds dark brown, (1.5-)1.8-2.5 × 0.7-1 mm. 2n = 40.
"Much like no. 1 [Camelina microcarpa Andrz.]; stem and lvs glabrous to sparsely pubescent, the simple hairs not projecting beyond the stellate ones; frs 7–9 mm, inconspicuously veiny, on pedicels 10–21 mm; seeds 1–2 mm; 2n=40. Native of the Old World, established as a casual weed in n. U.S. and adj. Can., less common with us than no. 1 [Camelina microcarpa Andrz.]."
Annual or biennial, 30-60 (-80) cm tall, branched mostly from the base, glabrous or sometimes sparsely hairy below with simple and branched hairs. Basal leaves oblong-lanceolate, 15-50 mm long, 5-10 (-15) mm broad, cuneate below, sessile, entire or irregularly toothed; upper leaves lanceolate or linear, sessile, sagittate-amplexicaul, entire or toothed. Racemes 30-70-flowered, up to 30 cm long in fruit. Flowers c. 3.5 mm across, yellow; pedicels 10-20 (-25) mm long in fruit, rigid, ascending. Sepals c. 2.5 mm long. Petals c. 5 mm long. Siliculae obovoid, 7-9 mm long, 4-5 mm broad, apex rounded; valves convex, glabrous, with a distinct mid-rib; style 1.5-2 mm long with capitate stigma; seeds 9-10 in each locule, c. 1.5 mm long, ovoid, brown.
Ähnlich wie C. microcarpa, aber kahl oder nur mit wenigen kleinen Haaren, Kelchblätter 2,5–3,5 mm, Kronblätter 4–5,5 mm lang, Schötchen ohne Griffel 7–10 mm lang, Samen 1,6–2,5 mm lang.
