Biennials or perennials; short-lived; apomictic; caudex present or absent. Stems usually 1 per caudex branch, arising from center of rosette near ground surface, 1.5-5 dm, densely pubescent proximally, trichomes short-stalked, 2-6-rayed, 0.2-0.5 mm, glabrous or sparsely pubescent distally. Basal leaves: blade oblanceolate, 2-10 mm wide, margins usually dentate, sometimes ciliate near petiole base, trichomes (usually spurred), to 0.7 mm, surfaces moderately to densely pubescent, trichomes short-stalked, 4-8-rayed, 0.1-0.4 mm. Cauline leaves: 15-36, sometimes concealing stem proximally; blade auricles 1-3 mm, surfaces of distalmost leaves sparsely pubescent. Racemes 20-55-flowered, usually unbranched. Fruiting pedicels reflexed to divaricate-descending, usually curved downward, 8-14 mm, usually pubescent, rarely glabrous, trichomes subappressed, branched. Flowers divaricate-descending at anthesis; sepals pubescent; petals pale lavender, 5-8.5 × 1-2 mm, glabrous; pollen spheroid. Fruits reflexed to pendent, rarely appressed to rachis, not secund, straight or slightly curved, edges parallel, 4-6 cm × 1-2 mm; valves glabrous; ovules 100-128 per ovary; style 0.05-0.5 mm.
