Stems more or less loosely cespitose, a few to several branched at base, ultimate branches terminated in rosettes and covered with leaf remains of previous years. Basal leaves rosulate, persistent; petiole up to 5 mm, ciliate with simple trichomes; leaf blade oblong-spatulate, 7?18 mm × 2?5 mm, densely pubescent with subsessile stellate trichomes with 1 or 2 rays, base attenuate, margin entire or 1?3 toothed on each side, ciliate with simple trichomes, apex obtuse to acute. Each stem erect, simple, sparsely pubescent with stellate trichomes, glabrous distally. Cauline leaves 1 to 3, sessile; leaf blade ovate to oblong, 6?12 × 2?5 mm, pubescent as basal leaves, base obtuse, margin entire or 1?3-toothed, apex acute. Racemes 7?17-flowered, rather loose, spreading, elongated in fruit. Fruiting pedicels 4?13 mm, straight, slender, glabrous, almost perpendicular to axis in fruit. Sepals ovate-oblong, 1.8?2.5 × 0.9?1.3 mm, erect, abaxially sparsely pubescent with short simple hairs, base of lateral pair not saccate, margin membranous. Petals white, narrowly obovate, 4?6 × 2?3 mm, apex subemarginate. Filaments 1.5?2.5 mm; anthers ovate, 0.2?0.3 mm. Ovules 12?24 per ovary.
