Annuals, biennials, or perennials; pubescent, trichomes branched, or mixed with simple, larger ones. Stems decumbent to procumbent, (slender), 1–5 dm. Basal leaves: blade (oblanceolate), 3–10 cm × 10–30 mm, margins sinuate-dentate to somewhat lobed or incised, surfaces densely pubescent. Cauline leaves: blade obovate-elliptic to oblong, 1–4 cm × 5–20 mm, base cuneate to auriculate (narrowed toward base), margins sinuate-dentate to incised, (surfaces densely pubescent). Fruiting pedicels recurved, slightly curved, 1–3 cm, (racemes lax in fruit), densely pubescent. Flowers: sepals (green), 4–5.5 × 1.5–2 mm, (nearly acuminate), pubescent or hirsute (trichomes branched); petals light yellow (often drying purplish), 5–9 × 4–6 mm, (claw relatively short), apex rounded; filaments not dilated basally, (2.5–3.5 mm, anthers sagittate, 2–3 mm, glands with horn-like projections at base of filaments). Fruits sessile, orbicular, elliptic, or cordate, 5–9 × 4–9 mm, (angustiseptate or slightly so); valves (rounded or strongly keeled), densely pubescent, trichomes branched, sometimes with simple, larger ones; replum oblong to nearly elliptical; septum complete, (transparent); ovules 14–32 per ovary, (attached in proximal 1/2); style 1–1.5 mm; stigma expanded. Seeds suborbicular (slightly longer than broad), 1–2.2 mm.
