Stems erect or prostrate, leafy or rarely leafless and plant scapose. Basal leaves petiolate, rosulate or not, simple and entire, toothed, or 1–3-pinnatisect, or palmately lobed, sometimes trifoliolate, pinnately, palmately, or bipinnately compound; cauline leaves alternate, rarely opposite or whorld, simple or compound as basal leaves, petiolate or sessile and base cuneate to attenuate or auriculate to sagittate, margin entire, dentate, or variously lobed. Racemes several to many-flowered, ebracteate or rarely bracteate throughout, corymbose or in panicles, elongated in fruit; rachis straight or rarely flexuous; fruiting pedicels slender or thickened, erect, divaricate, or reflexed. Sepals ovate or oblong, free, caducous or rarely persistent, erect to rarely spreading, equal or unequal, base of lateral pair saccate or not. Petals white, pink, purple, or violet, never yellow, erect to spreading, longer than sepals, rarely absent; blade obovate, spatulate, oblong, or oblanceolate, apex obtuse or emarginate; claw absent or strongly differentiated from blade, longer to shorter than sepals, glabrous, unappendaged, entire. Stamens 6 and slightly to strongly tetradynamous, rarely 4 and equal in length, erect or spreading, exserted or included; filaments wingless, unappendaged, glabrous, free, dilated or not at base; anthers ovate to oblong or linear, not apiculate at apex. Nectar glands confluent and subtending bases of all stamens; median nectaries 2 or rarely 4 or absent; lateral nectaries annular or semiannular. Ovules 4-80 per ovary; placentation parietal.
