Stems usually 1 per caudex branch, arising from center of rosette near ground surface, 0.4-1.4 dm, densely pubescent proximally, trichomes short-stalked, 2- or 3-rayed, 0.2-0.3 mm, sparsely to moderately pubescent distally. Basal leaves: blade narrowly oblanceolate to linear, 0.8-1.8 mm wide, margins entire, ciliate along petiole, trichomes (simple), to 0.8 mm, surfaces densely pubescent, trichomes short-stalked, 2- or 3-rayed, 0.2-0.3 mm. Cauline leaves: 6-10, somewhat concealing stem proximally; blade auricles to 0.5 mm, surfaces of distalmost leaves pubescent. Racemes 6-15-flowered, usually unbranched. Fruiting pedicels ascending, straight, 3-8 mm, pubescent, trichomes appressed, branched. Flowers ascending at anthesis; sepals pubescent; petals purplish, 4-5 × 1-1.8 mm, glabrous; pollen ellipsoid. Fruits suberect or ascending, sometimes appressed to rachis, not secund, straight, edges parallel, 2.5-4 cm × 1.2-1.8 mm; valves glabrous; ovules 50-60 per ovary; style 0.05-0.1 mm.
