Perennials; caudex simple; densely pubescent, trichomes (sessile or nearly so), 4–6(–10)-rayed, rays usually furcate near base, rarely bifurcate, (umbonate, tuberculate throughout). Stems simple from base, erect, (usually unbranched), to 4.5 dm. Basal leaves: blade suborbicular to elliptic, 2–9.5(–11.5) cm, margins entire, sinuate, coarsely dentate, or almost lyrate-pinnatifid. Cauline leaves similar to basal, blade narrowly linear or, sometimes, orbicular. Racemes loose (lax). Fruiting pedicels (recurved, straight, curved, or sigmoid), 6–20 mm. Flowers: sepals elliptic or ovate, (2–)3.5–7.5 mm, (cucullate); petals 6–11 mm. Fruits obovoid to subglobose, not inflated (not angustiseptate), 3–6 mm; valves sparsely pubescent, sometimes glabrous inside, trichomes sessile or stalked; ovules 4(–8) per ovary; style (1.6–)3–6 mm. Seeds flattened. 2n = 10, 30.
