Plants perennial; taproot stout; caudex simple or sparsely branched, woody. Stems usually simple proximal to inflorescence, 30–50(–70) cm, puberulent and shortly stipitate-glandular, espec-ially distally. Leaves 2 per node, gradually reduced distally; basal petiolate, blade oblanceolate, spatulate, 5–9 cm × 7–15 mm (including petiole), apex acute to obtuse, usually glabrous adaxially, sparsely pubescent abaxially; cauline in 4–6 pairs, blade linear-lanceolate, 1–6(–8) cm × 2–6 mm, puberulent and shortly stipitate-glandular. Inflorescences thyrsate, 3–25-flowered, open, bracteate, pedunculate, stipitate-glandular, viscid; bracts narrowly lanceolate, 2–25 mm, apex acuminate. Pedicels ascending. Flowers: calyx prominently 10-veined, narrowly campanulate, umbilicate, somewhat clavate and constricted below middle around carpophore, 9–15 × 3–4 mm in flower, broadening to 7 mm in fruit, membranous, shortly stipitate-glandular, veins parallel, slender, tinged dark red, with pale commissures, lobes ovate-lanceolate, obtuse, 2–3 mm, margins scarious; corolla creamy white, sometimes pink tinged, clawed, claw equaling calyx, glabrous, broadening only slightly into limb 3–8 mm, limb with 4–6 linear lobes, some splitting to 10 linear segments, appendages 4–6, linear, 1–1.5 mm, apex acute; stamens ca. equaling petals; filaments glabrous; stigmas 3(–5), ca. equaling petals. Capsules ellipsoid, slightly longer than calyx, opening by 6 (or 8 or 10) very brittle teeth; carpophore 2–4 mm. Seeds brown, ± reniform, angular, glossy, shallowly tuberculate. 2n = 48.
