Perennial herbs, often tufted and pilose with simple or forked hairs, very rarely glabrous or subglabrous, often suberect or procumbent, branched mostly from below. Leaves spathulate or obovate-oblong, (1-) 3-5 (-10)-toothed or lobulate above, ± entire below, sessile or subsessile; basal leaves rosulate, somewhat larger than the stem or upper leaves. Racemes few to many flowered, often bracteate below, sometimes scapose. Flowers white or lilac, rarely mauve or yellowish with a lilac tinge inside; pedicels often turning towards one side, pilose. Sepals subequal to unequal, free or connate below, not or hardly saccate at base, sometimes persistent. Petals about twice as long as the sepals, spathulate. Stamens 6; filaments not appendaged. Lateral nectar glands annular; middle glands joining the laterals. Ovary linear to elliptic-ovate, often pilose, few to many ovuled; stigma usually depressed, subretuse, sessile or subsessile (very rarely on a short style). Fruits (usually siliquae) ovate-oblong, lanceolate, linear-oblong to linear, flattenea, usually bilocular and tardily dehiscent, pilose to glabrous; septum membranous, thinnest in the middle, complete, incomplete or obsolete; seeds 1-2-seriate, few to many, mucilaginous or not when wet; radicle accumbent rarely incumbent.
