Basal leaves in juvenile plants subrosulate, short petiolate, obovate, 1–2.7 x 0.5–1.4 cm, apically dentate, teeth with short, bristly trichomes at tips; middle cauline leaves fleshy, overlapping, broadly ovate to orbicular, 0.7–3.5 x 0.5–2.4 cm, glabrous or rarely with few hairs apically, sessile and auriculate to amplexicaul at base, usually entire, apex obtuse; upper leaves similar in size, not overlapping. Racemes ebracteate, lax in fruit, without a terminal cluster of sterile flowers; fruiting pedicels erect to ascending, straight, 3–8 mm. Flowers: sepals forming campanulate calyx, yellowish green in bud, purple in flower, ovate, 4–7 mm, not keeled, ascending, apex with short, bristly, flattened trichomes; petals purplish with darker veins, 5–9 mm; blade oblong to ovate, 0.5–3 x 0.3–0.7 mm, slightly crisped; claw oblanceolate, 4–7 mm, wider than blade; filaments in 3 pairs of unequal length, free; adaxial pair 5–7 mm; abaxial pair 4–6 mm; lateral pair 3–5 mm; anthers of all stamens fertile, 2.5–3.5 mm. Fruit 2–7(–8.2) cm x 2–3 mm, erect to ascending, distinctly flattened, often strongly recurved, not torulose; valves glabrous, with obscure midvein except sometimes for base, margins somewhat thickened; gynophore 1–3 mm; replum straight; style 0.4–1 mm; stigmas entire; ovules and seeds 16–30 per fruit. Seeds oblong to broadly ovate, 3–4 x 1.7–2 mm; wing absent or 0.1–0.25 mm wide at seed apex, narrower at margin. 2n = 28, 56.
