Plants sometimes canescent basally; caudex branched. Stems: several from base, unbranched, (0.3-)0.5-1.4 (-2) dm, trichomes simple, 0.3-1 mm, mixed with smaller, dendritic ones, (sometimes simple ones absent). Basal leaves: petiole 0.7-3(-4) cm, often ciliate, trichomes simple; blade usually linear to oblanceolate or spatulate, rarely obovate, (0.5-)0.8-2.2(-3.5) cm × 0.7-5 (-7) mm, margins usually entire, rarely apically 3 or 5-toothed or-lobed, apex obtuse to rounded, (surfaces densely tomentose, grayish, trichomes mostly dendritic, mixed with fewer, simple ones, to 1 mm). Cauline leaves shortly petiolate; blade similar to basal, smaller distally, margins usually entire, rarely lobed. Racemes elongated in fruit. Fruiting pedicels divaricate to ascending, (forming 30-70˚ angle), proximalmost bracteate, 4-12 mm, pubescent, trichomes simple mixed with smaller, dendritic ones. Flowers: sepals 2.5-3.5 mm; petals white or creamy white, suborbicular to obovate, 4-6 × 2-3(-4) mm, narrowed to claw, 1-2(-3) mm, apex rounded; anthers oblong, 0.5-0.7 mm. Fruits divaricate to ascending, ellipsoid to oblong, subterete or slightly 4-angled, 6-10 × 1.5-2.5 mm, base and apex cuneate; valves each with prominent midvein; ovules 4-8 per ovary; style 0.1-0.5 mm. Seeds 1.5-2 × 0.9-1.2 mm. 2n = 12, 22, 24.
