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).
