simple, 5–15 cm, pubescent and viscid, with stipitate glands.

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.

basal with blade 1-veined, oblanceolate, broadly spatulate, 1–4 cm × 2–8 mm, apex obtuse to acute, glandular-puberulent throughout, rarely subglabrous adaxially;

cauline in 3–6 pairs, sessile, reduced distally, blade lanceolate, narrowly elliptic, or oblanceolate, 2–4 cm × 2–8 mm, apex ± acute, glandular-puberulent throughout.

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.

usually with solitary terminal flower, sometimes cymose, to 8-flowered, open.

1(–3)-flowered.

erect or angled near tip with flowers slightly nodding, 1–3 times longer than calyx, glandular-puberulent, often densely so.

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 1/2 pedicel diam.

calyx prominently 10-veined, campanulate, not contracted proximally around carpophore, 15–20 × 4–8 mm, papery, margins dentate, veins parallel, usually purple tinged, with pale commissures;

lobes ovate, 3–5 mm, glandular-puberulent, midrib triangular, margins purple tinged, broad, membranous, apex obtuse;

corolla bright pink, clawed, claw equaling calyx, broad and ligulate but abruptly contracted into limb, limb broadly cuneate, shallowly to deeply 2–4-lobed, 5–15 mm, lobes broad or narrow, appendages absent or to 2 mm, margins erose;

stamens slightly longer than corolla claw;

stigmas 3(–5), slightly longer than corolla claw.

10–12 mm diam.;

calyx prominently 10-veined, ellipsoid, somewhat inflated and contracted at mouth to 1/2–2/3 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.

equaling calyx, opening by 6 (or 8 or 10) lanceolate teeth;

carpophore 1–2.5 mm.

equaling calyx, opening by 5 recurved teeth, which later split into 10;

carpophore very short or absent.

brown, broadly reniform, flattened, 2–2.5 mm, rugose, more coarsely so on margins.
