Perennials; (cespitose); caudex branched (with persistent leaf remains); not scapose. Stems unbranched, 0.1–0.35 dm, pilose throughout, trichomes simple, (slightly crisped), 0.4–0.9 mm. Basal leaves rosulate; petiolate; petiole base and margin ciliate, (trichomes usually simple, rarely some 2-rayed, 0.2–0.7 mm); blade oblanceolate to linear-oblanceolate, 0.6–1.5 cm × 0.5–2 mm, margins entire or sparsely dentate, surfaces pubescent, abaxially with simple trichomes, 0.3–0.9 mm, with fewer, 2(or 3)-rayed ones, 0.07–0.3 mm, adaxially with simple trichomes. Cauline leaves 1–3; sessile; blade lanceolate, margins entire, surfaces pubescent as basal. Racemes 2–7-flowered, ebracteate or proximalmost 1 or 2 flowers bracteate, slightly elongated in fruit; rachis not flexuous, glabrous.
