Characteristics

Erect herbs up to 1 m or more high. Stems simple or freely branched in the upper part, densely appressed-strigose with coarse retrorse hairs in the lower part, sparsely higher up. Basal leaves petiolate, lyrate-pinnatifid, 4-6-jugate with small deltoid-oblong or larger oblong-ovate lateral lobes; terminal lobe large, mostly ± ovate; petioles retrorsely hispid, the blade thinly hispid. Stem leaves with gradually shorter petioles, the upper ones sessile, sometimes auriculate-amplexicaul; lobes also reducing in number and size up the stem, the upper leaves oblong-lanceolate, serrate-dentate or repand dentate-lobate, sometimes crispate, thinly hispid or subglabrous. Racemes terminal, dense in flower, lax in fruit, naked or the lower pedicels subtended by leafy bracts. Sepals 3.5-5 mm long, narrowly oblong, hairy or glabrous. Petals 6.5-9 mm long, narrowly oblanceolate to narrowly obovate, long-clawed. Anthers about level with the stigma, 1.5-1.8 mm long. Ovary glabrous, linear with a stout style. Siliquae on 1-2(-4) cm long, erect or wide-spreading pedicels, including the beak 2.5-4.8 cm long, 1.5-2.2 mm in diameter, linear, erect or ascending; valves glabrous, rounded on the back, the midrib conspicuous, when fully ripe reticulately veined and bulgep by the seeds, the apex emarginate; beak 3-10.5 mm long, stout, conical-subulate, ribbed, 2-seeded; stigma small, shallowly 2-lobed. Seeds ±1-2 x 1 mm, oblong-orbicular, red-brown, the seed-coat minutely reticulate.
