Perennials; (cespitose, caudex simple or few-branched); not scapose; pubescent or glabrous, trichomes simple. Stems erect, unbranched or branched distally. Leaves basal and cauline; petiolate or sessile; basal rosulate, petiolate, blade margins entire; cauline sessile, blade (base not auriculate), margins entire. Racemes (corymbose, several-flowered), considerably elongated in fruit. Fruiting pedicels ascending to suberect, slender. Flowers: sepals (erect), oblong-ovate, (glabrous); petals white, obovate to spatulate, (longer than sepals, claw obscurely differentiated from blade, apex obtuse); stamens slightly tetradynamous; filaments not or slightly dilated basally; anthers ovate, (apex obtuse); nectar glands confluent, subtending bases of stamens. Fruits sessile or subsessile, linear to linear-lanceolate, torulose, terete; valves each with obscure midvein extending to middle, glabrous; replum rounded; septum complete; ovules 6–12 per ovary; stigma capitate. Seeds uniseriate, plump, not winged, narrowly oblong; seed-coat not mucilaginous when wetted; cotyledons incumbent. x = 7.
