Herbs, perennial, often loosely pulvinate or cespitose; caudex with many slender branches terminating in rosettes. Trichomes short stalked or sessile, stellate, with simple or forked rays, these most frequently mixed with coarser stalked, forked and setose simple ones. Multicellular glands absent. Stems erect to decumbent, branched, leafy. Basal leaves petiolate, rosulate or not, simple, entire or dentate; cauline leaves petiolate to subsessile, entire or dentate, not auriculate at base. Racemes few to many flowered, ebracteate, elongated in fruit; rachis straight or flexuous; fruiting pedicels ascending to divaricate, slender, persistent. Sepals oblong, erect, caducous, glabrous or pubescent, unequal, base of lateral pair saccate. Petals pink to purple-violet, or rarely white, erect and with flaring blade, longer than sepals; blade suborbicular, obovate, to spatulate, rounded or retuse to emarginate; claws as long as or longer than sepals, well differentiated from blade, glabrous, unappendaged, entire. Stamens 6, slightly exserted, erect, tetradynamous; filaments narrowly winged, glabrous, free, lateral pair with or without toothed appendage; anthers ovate, not apiculate. Nectar glands lateral, semi-annular, extrastaminal; median glands absent. Ovules 10‒40 per ovary, placentation parietal. Fruit dehiscent, capsular siliques or rarely silicles, linear, oblong, or elliptic, latiseptate or terete, not or rarely inflated, unsegmented; valves papery, with a distinct midvein, pubescent or glabrous, not torulose, not keeled, wingless, unappendaged; gynophore absent; replum rounded, visible; septum complete or occasionally perforate, membranous, not veined; style slender, 2‒12 mm long, cylindrical, persistent; stigma capitate, entire, unappendaged. Seeds biseriate, wingless, elliptic, oblong, ovate, or suborbicular, flattened; seed coat not mucilaginous when wetted; cotyledons accumbent.
