Herbs annual, biennial, or perennial with stolons or woody caudex. Trichomes simple, mixed with stalked, 1-3-forked ones. Stems erect or decumbent, often several from base, usually glabrous above. Basal leaves rosulate, entire, toothed, or pinnately lobed. Cauline leaves petiolate or subsessile, entire, dentate, or rarely lyrate. Racemes few to several flowered, ebracteate. Fruiting pedicels ascending or divaricate or slightly reflexed. Sepals oblong, erect or ascending, glabrous or pubescent, base of lateral pair subsaccate or not. Petals white, pink, or purple; blade obovate, spatulate, or oblanceolate, apex obtuse or emarginate; claw distinct or not. Stamens 6, erect, slightly tetradynamous; filaments not dilated basally; anthers oblong, obtuse. Nectar glands confluent, subtending bases of filaments. Ovules 15-80 per ovary. Fruit dehiscent siliques, linear or cylindric, terete or flattened and latiseptate, shortly stipitate or subsessile; valves papery, veinless or midvein distinct, glabrous, smooth or somewhat torulose; replum rounded; septum complete; style obsolete or to 1 mm; stigma capitate, entire. Seeds numerous, uniseriate, wingless or margined, oblong or ellipsoid, plump or flattened; seed coat minutely reticulate, mucilaginous or not when wetted; cotyledons accumbent or rarely incumbent.
Annual to perennial rather small and delicate herbs with a taproot, glabrous or with stellate and bifid as well as simple hairs. Stems ± erect, little branched. Racemes ebracteate or bracteate, densely corymbose, with small flowers, in fruit elongate, cylindrical and lax. Sepals not or slightly saccate, not spreading. Petals white, yellow or violet. Stamens usually 6; filaments linear. Nectaries as ring-, horseshoe-shaped or hemispherical tissues around or outside the lateral stamens, and as a low wall outside each pair of median stamens. Ovary narrowly cylindrical, with almost sessile stigma; ovules numerous. Fruit a siliqua, dehiscent, linear; septum narrow; valves thin, without marked nerves. Seeds very small, ellipsoid, not mucilaginous.
Sep oblong, obtuse; pet white, spatulate, gradually narrowed to the base; filaments capillary; anthers ovate; short stamens subtended by a minute semicircular gland; each pair of long stamens separated by a minute gland; ovary cylindric, ovules numerous; style undifferentiated; stigma truncate; fr linear, subterete, the valves with conspicuous midnerve, the cells of the septum vertically elongate, herbs, ± pubescent with branched hairs. 15, N. Hemisphere.
