Annual or biennial herbs, rarely perennial, woody at the base. Stems 10-50 cm tall, sparsely hispid in the lower part or almost glabrous; the hairs ± retrorse. Leaves mostly basal, in annual plants in a rosette, in older plants more laxly tufted; oblanceolate or ± spathulate, petiolate, lyrate-pinnatifid or dentate, glabrous or sparsely hispid on the lower surface; stem leaves few or none, subsessile. Inflorescence few- to many-flowerÂed, subdense at flowering, lax in fruit. Flowers yellow, sometimes tinged with violet when fading, small, the petals being 5-8 mm long. Fruiting pedicels ascending. Siliqiiae 2-4 cm long, 1-5-2'5 mm broad, linear, the margin straight; valves smooth, 1-nerved, eventually ± bulged by the seeds; style 1 • 5-2 • 5 mm long, narrowly cylindrical or ± obconical; stigma capitate, very slightly 2-lobed. Seeds mostly in 2 rows, ± ovoid, c. 1 X 0-6 mm, subcompressed, brown, smooth. Fig. 1:3.
