Plants scapose; densely pubes-cent 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.
