General Description
Plants with a branched caudex. Stems ascending to erect, 25–100 cm. Herbage sparsely strigose to minutely puberulent. Leaves basal and cauline; blades lanceolate to ovate, acute to acuminate, 3–14 cm long; the basal subtruncate; lateral veins obvious. Flowers: calyx strigose, 2–6 mm long, divided to below the middle with acute tips; corolla 9–15 mm long; limb 1.2 to 1.6 times as long as the tube; tube with or without hairs within; filaments inserted at the fornices, ca. as long as the anthers; style higher than the anthers, sometimes slightly exserted. Nutlets 3–4 mm long (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
