     Herbs perennial, cespitose, rarely scapose, not pulvinate; caudex simple or several branched. Stems 3–17(–24) cm, unbranched, pubescent throughout with 4–10-rayed trichomes 0.1–0.3 mm, often some rays branched, simple trichomes usually present, fewer, to 0.7 mm. Basal leaves rosulate, oblanceolate to narrowly obovate, 4–23(–30) × 1.5–6.5 mm, entire or rarely with 1 tooth on each side; both surfaces densely pubescent with minutely stalked, 8–12-rayed stellate trichomes 0.2–0.4 mm, sometimes surfaces with a few coarser simple or 2-rayed trichomes; midvein distinct abaxially, petiolar base ciliate with simple trichomes 0.2–0.8 mm; cauline leaves of flowering stems absent or 1(–3), ovate or oblong to lanceolate, entire, sessile, pubescent as basal leaves. Racemes ebracteate, 3–18(–25)-flowered, elongated in fruit; rachis pubescent as stem, not flexuous; lowermost fruiting pedicels (1.5–)2–6 mm, divaricate-ascending or ascending, straight, pubescent with stalked stellate and sometimes fewer simple trichomes.
