Perennials; (densely matted); caudex branched (with persistent leaf remains, some branches terminating in sterile rosettes); scapose. Stems unbranched, 0.04-0.4 dm, usually pubescent throughout, sometimes glabrous basally, trichomes simple, 0.1-1 mm, with 2-rayed ones. Basal leaves (densely imbricate); rosulate; petiolate; petiole base and margin ciliate, (trichomes simple, to 1.4 mm); blade oblanceolate to spatulate or obovate, 0.4-0.8(-1) cm × 2-3.5(-4.5) mm, margins entire, surfaces usually sparsely to densely pilose with simple trichomes, to 1.4 mm, with much fewer, stalked, 2-rayed ones, (sometimes surfaces glabrous, or adaxially only, midvein obscure abaxially). Cauline leaves 0. Racemes (1 or) 2-5(-9)-flowered, ebracteate, not or slightly elongated in fruit; rachis not flexuous, pubescent as stem. Fruiting pedicels divaricate, straight, 1.5-4(-6) mm, pubescent, trichomes simple with fewer, 2-rayed, stalked ones. Flowers: sepals oblong, 2-3 mm, glabrous or sparsely pubescent, (trichomes simple); petals yellowish green to pale yellow, linear-oblanceolate, 3-4 × 0.5-0.8 mm; anthers oblong, 0.4-0.5 mm. Fruits broadly obovoid to subglobose, plane, slightly flattened, 3-5 × 3-4.5 mm; valves glabrous or pubescent, trichomes simple, 0.1-0.3 mm; ovules 4-8 per ovary; style 0.1-0.4 mm. Seeds oblong, (slightly flattened), 1.4-1.8 × 0.9-1.1 mm.
