Perennials; (cespitose); caudex branched (covered with per-sistent petiole remains); scapose. Stems unbranched, 0.2-1.1 dm, pubescent proximally, trichomes short-stalked, 2-5-rayed, 0.1-0.5 mm, (some rays spurred). Basal leaves rosulate; petiolate; petiole base and margin ciliate, (trichomes simple, 0.3-1 mm); blade oblanceolate to lanceolate, 0.8-2.2 cm × 2-6 mm, margins often entire, surfaces pubescent abaxially with stalked, 2-5-rayed, stellate trichomes, 0.1-0.4 mm, often some rays spurred and trichomes appearing subdendritic, rarely glabrate, or with simple and 2-rayed ones, (midvein obscure abaxially, not thickened), adaxially glabrous or sparsely pubescent with simple trichomes, sometimes with long-stalked, 2-or 3-rayed ones. Cauline leaves 0. Racemes (2-)4-13-flowered, ebracteate, (subcorymbose), not elongated in fruit; rachis not flexuous, pubescent as stem. Fruiting pedicels subhorizontal to divaricate-ascending (not appressed to rachis), often slightly curved upward, 4-7(-10) mm, pubescent, trichomes simple (0.4-1 mm), and 2-4-rayed (0.1-0.4 mm). Flowers: sepals (grayish white), ovate to broadly so, 2.5-3 mm, pubescent, (trichomes simple and stalked, 2-rayed); petals creamy white to yellow, broadly obovate, 3.5-5 × 2.5-3.5 mm; anthers ovate, 0.4-0.5 mm. Fruits ovate to ovate-oblong, plane, flattened, 5-10 × 3-5 mm; valves puberulent along replum, trichomes simple, 0.1-0.3 mm; ovules (16-)18-28 per ovary; style 0.2-0.6 mm (stigma as wide as style).
