Plants scapose; moderately to densely lanate-pilose, trichomes simple and 2-forked. Stems simple or few to several from base, erect to ascending, (branched or unbranched), 0.4-1.1(-1.3) dm. Basal leaves: blade linear-spatulate, 0.7-2 (-3) cm × 0.7-2.5(-3.5) mm, base (membranous), broadly expanded near point of attachment, margins entire, (ciliate, trichomes long, 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-)2.5-6 mm. Flowers: sepals 2.8-3.5 × (1.3-)1.6-2.5 mm; petals white, (obovate), 4.7-6.6 × 3-5.1 mm, (claw short, apex rounded); filaments 2-3 mm; anthers ovoid, 0.4-0.6 mm. Fruits ovoid or globose, not torulose, (0.4-)0.5-0.6 cm × (2.5-)3-4 mm; valves densely to moderately pubescent, trichomes relatively short, simple and 2-forked; septum margin not expanded, or not basally; ovules 14-20 per ovary; style 1.2-2(-2.5) mm; stigma (broadly expanded), strongly or weakly 2-lobed.
