Herbs perennial, 4-20(-28) cm tall, cespitose. Caudex slender, few branched, ultimate branches terminated in rosettes, covered with petiolar remains of previous years. Stems erect, simple, tomentose with subsessile stellate trichomes. Basal leaves rosulate; petiole to 6 mm, often undifferentiated; leaf blade lanceolate or elliptic-oblong, (3-)4-15(-18) × 1-4(-5) mm, tomentose with sessile, 4-rayed stellate trichomes the rays of which with 1 or 2 lateral branches, base attenuate to cuneate, margin entire or 1-3-toothed on each side, often ciliate at least near base, apex acute. Cauline leaves 1-4(or 5), sessile; leaf blade ovate, oblong, or elliptic, (4-)6-10(-20) × 1.5-4(-7) mm, pubescent as basal leaves, base cuneate to obtuse, margin entire or 1-5-toothed on each side, often subsetose ciliate at base, apex acute. Racemes (5-)7-20(-25)-flowered, ebracteate or lowermost flowers bracteate, at least lowermost portion elongated in fruit. Fruiting pedicels (1-)2-6(-10) mm, erect or ascending, straight, often subappressed to rachis, tomentose all around with subsessile, stellate trichomes rarely mixed with fewer simple ones. Sepals oblong, 1.2-1.8 × 0.5-0.9 mm, erect, abaxially pilose, base of lateral pair not saccate, margin membranous. Petals white, spatulate, 2-3.5 × 0.8-1.1 mm, apex subemarginate or rounded; claw absent. Filaments 1-1.8 mm; anthers ovate, ca. 0.2 mm. Ovules 12-20(-22) per ovary. Fruit narrowly oblong-ellipsoid to lanceolate-linear, (5-)7-10(-11) × 1.5-2 mm, erect to ascending, sometimes appressed to rachis, latiseptate, often twisted 2 or rarely 3 turns, rarely untwisted; valves tomentose or glabrous, obscurely veined, base obtuse, apex acute or acuminate; style 0.1-0.5 mm.
