Perennials; caudex simple or branched, (thickened by persistent leaf bases); densely pubescent (foliage usually scabrous), trichomes (sessile or short-stalked), several-rayed, rays furcate near base, (usually strongly umbonate, roughly tuberculate, less so over umbo). Stems few to several from base, erect or outer decumbent, 0.5–2.5 dm. Basal leaves: blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate. Cauline leaves: (proximal shortly petiolate, distal usually sessile); blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire. Racemes compact, (± subumbellate to densely corymbiform, elongated or not). Fruiting pedicels (usually spreading at right angles, sometimes nearly erect, ± straight), 5–15(–20) mm, (stout). Flowers: sepals ± elliptic, 4.5–7(–8.5) mm, (median pair thickened apically); petals (sometimes white), suborbicular to obovate or obdeltate, 6.5–15 mm, (base narrowing to broad claw, apex sometimes emarginated). Fruits (sessile or shortly stipitate, less than 1 mm), subglobose to broadly ellipsoid, inflated or slightly compressed (terete or subterete), (4–)5–8(–9) mm; valves (not retaining seeds after dehiscence), glabrous; replum as wide as or wider than fruit; ovules 8–16 per ovary; style 4–8(–9) mm. Seeds flattened.
