    sparsely to densely pubescent throughout, or, rarely, glabrescent, trichomes short-stalked or subsessile, submalpighiaceous or, rarely, 2-forked, often mixed along petioles and stem base with simple ones.
    Stems usually few to several from base, rarely simple, ascending or erect, rarely subdecumbent, (0.4–) 0.8–2.5 (–3.5) dm.
    Basal leaves: blade obovate, spatulate, oblanceolate, oblong, or sublinear, (0.3–) 0.5–2 (–3.5) cm × 1–8 (–10) mm, base attenuate or cuneate, margins entire, sinuate-dentate, or pinnatifid, apex acute or obtuse, (surfaces sparsely to densely pubescent or, rarely, glabrous).
    Cauline leaves: 3 or more;
    blade similar to basal, smaller distally, distalmost sessile or subsessile.
    (Racemes bracteate proximally, very rarely throughout, elongated in fruit.) Fruiting pedicels erect, ascending, or divaricate, (2.5–) 3–8 (–12) mm.
    Flowers: sepals 2–3 × 0.8–1.2 mm, (sometimes slightly saccate basally);
    petals white, pink, or purple, (broadly obovate or spatulate), 3–5 (–8) × (1–) 1.5–2.5 (–4) mm, (apex rounded);
    filaments 2–3 (–4) mm;
    anthers oblong, 0.4–0.7mm, (apex apiculate).
    Fruits linear, torulose or not, (mostly straight), (0.9–) 1.2–2.5 (–3.2) cm × 0.6–1.8 (–2) mm (uniform in width);
    valves pubescent or, rarely, glabrescent, trichomes submalpighiaceous, rarely mixed with fewer, simple ones;
    ovules 20–44 per ovary;
    style 0.3–0.8 (–1) mm;
    stigma entire or strongly 2–lobed.
    Seeds uniseriate, oblong, 0.6–0.9× 0.4–0.5 mm.
