Plants scapose; sparsely to densely pubescent, trichomes simple, 2- or 3-forked. Stems simple or few to several from base, ascending or erect, rarely decumbent to prostrate, (0.1–)0.3–1.7(–2.3) dm. Basal leaves: blade (often somewhat fleshy), linear-oblanceolate to broadly spatulate, (0.4–)0.8–6(–7.9) cm × (0.3–)0.6–4(–6) mm, base (membranous), broadly expanded near point of attachment, margins usually entire, sometimes weakly dentate with 1 or 2 teeth per side, apex obtuse, (often with a tuft of long, simple hairs, surfaces sparsely to moderately pubescent). Cauline leaves 0 or 1 (or a leaflike bract subtending proximalmost pedicel). (Racemes elongated or not in fruit.) Fruiting pedicels ascending-erect to divaricate, (0.9–)1.9–7.5(–8.6) mm. Flowers: sepals (1.6–)1.9–3.7 × (0.7–)1–2 mm; petals white or purplish (broadly obovate or spatulate), (2.1–)2.4–4.5(–4.7) × (0.7–)1–3(–3.2) mm, (apex rounded); filaments 1.7–2.2 mm; anthers oblong, 0.3–0.5 mm. Fruits oval-elliptic, oblong-elliptic, oblong, or oblong-lanceoloid, sometimes slightly torulose, (straight or somewhat curved), (0.3–)0.5–1.2(–1.5) cm × (0.8–)1.1–3(–3.6) mm; valves sparsely to densely pubescent or glabrous, trichomes simple or 2 (or 3)-forked; septum margin not expanded or not basally; ovules (5–)16–20 per ovary; style (0.3–)0.5–1.8(–2) mm; stigma entire or strongly 2-lobed, (narrow or broad). Seeds biseriate, oblong, (0.7–)0.9–1.6 × 0.4–0.8(–0.9) mm.
