Plants sometimes canescent basally; caudex branched. Stems: several from base, often unbranched, (0.4-)0.6-2 (-2.7) dm, trichomes simple, 0.5-1.3 mm, mixed with smaller, dendritic ones. Basal leaves: petiole 1-5(-8) cm, ciliate, trichomes simple; blade oblanceolate to obovate, or ovate to oblong in outline, (terminal segments linear, oblong, or ovate), (0.5-)1-3.5(-5.2) cm × 4-17 mm, (terminal segments 0.2-1.4 cm × 0.5-4 mm), margins 1-or 2-pinnatifid or-pinnatisect, apex obtuse or subacute. Cauline leaves shortly petiolate or sessile; blade similar to basal, smaller distally. Racemes elongated in fruit. Fruiting pedicels suberect to ascending, (subappressed to rachis, often forming less than 40˚ angle), proximalmost bracteate, 4-10(-14) mm, pubescent, trichomes simple (to 1.5 mm), mixed with smaller, dendritic ones. Flowers: sepals 2-3.5 mm; petals usually white, rarely pinkish or lavender, suborbicular to obovate, 3.5-6.5 × 1.5-3.5 mm, narrowed to claw, 1.5-3 mm, apex rounded; anthers oblong, 0.5-0.7 mm. Fruits usually suberect, rarely ascending, ellipsoid or oblong to linear, 4-angled, 5-13 × 1.5-2 mm, base and apex cuneate; valves each with prominent midvein; ovules 8-12(-14) per ovary; style 0.2-0.8 mm. Seeds 1.1-1.9 × 0.6-0.9 mm. 2n = 12, 22.
