Radical leaves usually rosulate, often petiolate, narrowed at base, rarely auriculate, ovate-oblong, entire or toothed; cauline leaves often sagittate, entire or toothed. Racemes elongate, usually bracteate at base, lax in fruit. Flowers white, purple or rose-coloured. Sepals spreading. Petals obovate or spathulate, rounded, almost twice as long as sepals, pink, white or purple. Stamens usually 6. Lateral nectar glands usually annular or semiannular; middle often torulose. Ovary linear, many-ovuled; stigma depressed. Fruits linear, often curved, compressed of terete, glabrous or hairy; valves usually weakly 1-nerved. Seeds few to many, 1 - 2 -seriate.
