Basal leaves rosulate; long-petiolate; petiole (winged, (1-) 4-15 cm), often not ciliate (or ciliate to blade apex, trichomes simple, 0.3-0.8 mm); blade (somewhat fleshy), oblanceolate to spatulate or obovate, (1-) 2-11(-17) cm × (5-)8-30(-45) mm, margins often coarsely dentate, (pubescent as petiole), surfaces usually pubescent, abaxially with stalked, 2-4-rayed trichomes, 0.05-0.25 mm, adaxially similar, or also with simple and long-stalked, 2-rayed trichomes, to 0.8 mm, rarely glabrescent, with mostly simple and 2-rayed trichomes. Cauline leaves 2-12(-16); sessile or petiolate; blade oblanceolate to obovate, margins dentate or entire, surfaces pubescent as basal. Racemes 5-26(-32)-flowered, ebracteate, elongated in fruit; rachis not flexuous, pubescent as stem. Fruiting pedicels horizontal to divaricate-ascending or ascending, usually straight, rarely curved upward, (5-)10-22(-27) mm, pubescent, trichomes 2-4-rayed (0.05-0.3 mm), sometimes with simple and spurred ones. Flowers: sepals broadly ovate, 3-4 mm, pubescent, (trichomes simple and short-stalked, 2-rayed); petals yellow, oblanceolate to spatulate, 4.5-7 × 1.8-3 mm; anthers oblong, 0.7-1 mm. Fruits oblong to lanceolate, or ovate to suborbicular, slightly twisted or plane, flattened, (6-)10-20(-25) × 4-7 (-9) mm; valves glabrous; ovules 24-52 per ovary; style (0.2-)0.4-1.6(-2) mm. Seeds ovoid, 1.4-2 × 0.8-1.2 mm. 2n = 36.
