Stems erect, simple proximal to inflorescence, 7-20 cm, with 2-4 pairs of leaves, short retrorse-pubescent proximally, stipitate-glandular and viscid distally, with purple-septate hairs. Leaves: basal pseudopetiolate, tufted, blade narrowly oblanceolate, 1.5-5 cm × 1.5-5 mm, base narrowed into long pseudopetiole, retrorse-puberulent on both surfaces; cauline sessile, connate at base, blade linear to linear-lanceolate or linear-oblanceolate, 1-4 cm × 1.5-4 mm, apex acute. Inflorescences 1(-3)-flowered. Pedicels erect, rarely somewhat curved or reflexed near tip, 0.5-2 cm, 1/2-3 times calyx, viscid with stipitate-glandular and purple-septate hairs, hairs less than 2 pedicel diam. Flowers 10-12 mm diam.; calyx prominently 10-veined, ellipsoid, somewhat inflated and contracted at mouth to 2-3 diam., 12-14 × 6-7 mm in flower, 14-17 × 7-8 mm in fruit, to 2 times as long as broad, papery, margins dentate, lobes 5, patent, ca. 2 mm, with broad, membranous margins, apex obtuse, pubescent, hairs short and stipitate-glandular and long purple-septate; corolla pink to purple, slightly longer than calyx, limb 2-lobed, 4-5 mm, with 2 short (ca. 0.5 mm) appendages; stamens equaling corolla; stigmas (4-)5, equaling corolla.
