Plants scapose; densely pubescent throughout or glabrous, trichomes simple and 2-forked. Stems simple or few to several from base, decumbent to prostrate or, sometimes, ascending, (unbranched), (0.3–)0.5–0.9(–1.4) dm. Basal leaves: blade spatulate to linear-spatulate, (0.5–)1–3(–4) cm × 1–4 mm, base (membranous), broadly expanded near point of attachment, margins entire, (ciliate, trichomes long, mostly simple), apex obtuse, often with tuft of hairs. Cauline leaves: 0 or 1 (or a leaflike bract subtending proximalmost pedicel). Fruiting pedicels divaricate to erect, 1.5–4 mm. Flowers: sepals 2–3.5 × 1–2 mm; petals white to purplish, (narrowly spatulate), 2–3.7 × 1–1.5 mm, (claw and blade not differentiated), apex rounded; filaments 2–2.5(–3) mm; anthers ovoid, 0.4–0.6 mm. Fruits ovoid to globose, not torulose, (0.4–)0.5–0.8(–1) cm × (2.5–)3–5 mm; valves densely pubescent or glabrous, trichomes 2-forked and simple; septum margin not expanded, or not basally; ovules 16–30 per ovary; style obsolete to 0.7(–1) mm; stigma strongly 2-lobed or entire. Seeds biseriate, oblong, (1.1–)1.2–1.4(–1.5) × (0.5–)0.7–0.8(–1) mm.
