Basal leaves rosulate; petiolate; petiole (0-0.5 cm), ciliate throughout; blade oblanceolate to obovate, 0.4-1.7(-2.3) cm × 1.6-4(-6) mm, margins usually entire, rarely denticulate, (sparsely ciliate, trichomes simple, 0.3-0.8 mm), surfaces pubescent, abaxially with stalked, (2-)4(-6)-rayed trichomes, (0.05-)0.1-0.6 mm, adaxially with simple and fewer, stalked, 2-4-rayed ones. Cauline leaves 0 or 1; sessile; blade ovate to lanceolate, margins entire, surfaces pubescent as basal. Racemes (2-)4-9(-12)-flowered, ebracteate, elongated in fruit; rachis slightly flexuous, glabrous. Fruiting pedicels divaricate-ascending, straight, 2-5(-8) mm, glabrous. Flowers: sepals ovate, 1.2-1.7 mm, pubescent, (trichomes simple and short-stalked, 2-or 3-rayed); petals yellowish (quickly fading white), spatulate, 1.8-2.2 × 0.6-1 mm; anthers ovate, 0.25-0.3 mm.
