Basal leaves rosulate, oblanceolate to obovate, 1–2(–3) cm × 2–7(–10) mm, entire or subapically denticulate; abaxial surface pubescent with a mixture of simple trichomes 0.6–1.3 mm and stalked, 2–4-rayed trichomes 0.1–0.8 mm; adaxial surfaces with simple and stalked, 2-rayed trichomes 0.4–1.2 mm; petiole obscure, margin ciliate with simple trichomes to 1.5 mm; cauline leaves of flowering stems 3–10(–17), lanceolate to ovate or oblong, entire, sessile, pubescent as basal leaves. Racemes ebracteate, (15–)20–51(–62)-flowered; rachis pubescent as stem, not flexuous; lowermost fruiting pedicels (2–)3–8(–10) mm, horizontal to divaricate-ascending, straight or curved upward, pubescent with simple and stalked, 2–4-rayed trichomes.
