Canad. J. Bot. 59: 1362. 1981.
Plants not cespitose; taproot producing 1–several shoots. Stems erect, branched, slender, (15–)20–40 cm, usually glabrous, rarely pubescent. Leaves: basal few, petiolate, petiole broadened at base and clasping stem, to equaling blade, blade narrowly lanceolate, spatulate, 2.5–15 cm × 1–6 mm, apex acute, glabrous to sparsely puberulent; cauline in 2–5 pairs, sessile, connate proximally, blade linear to linear-lanceolate, 1–12 cm × 1–5 mm, apex acute. Inflorescences branched, (1–)2–10-flowered; bracts and bracteoles very narrowly lanceolate, 5–15 mm. Pedicels ascending, deflexed at tip in flower, erect in fruit, slender, elongate, 1–7 cm, glabrous and sparsely pubescent. Flowers nodding; calyx veined, ovate-elliptic, 11–17 × 6–10 mm, glabrous to sparsely pubescent, veins purple, lobes spreading, ovate-triangular, 2–3 mm, apex short-acuminate; corolla dingy purple, slightly longer than calyx, claw shorter than calyx, limb ovate, 2-lobed, ca. 2 mm.

Subspecies ogilviensis is rare in scattered localities across the low arctic. Its appearance is distinct, with its taller, more-slender, branched, and usually glabrous stems. However, it appears to intergrade with subsp. uralensis, and further study is required to determine its status.
