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

several, simple or branched, spreading to ascending, leafy, 10–30 cm, densely pubescent, glandular.

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.

2 per node, mostly cauline, blade 1.5–6 cm × 3–14 mm, apex sharply acuminate, pubescent and viscid on both surfaces;

distal sessile, blade elliptic-lanceolate;

proximal short-petiolate, blade oblanceolate.

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

leafy, flowers terminal and axillary.

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

straight, rather slender, 1/5 times to equaling calyx.

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.

calyx prominently 10-veined, tubular to narrowly obconic in flower, 16–20 × 4–5 mm, clavate and broadening to 7 mm in fruit, narrowed proximally around carpophore, coarsely glandular-pubescent and viscid, veins parallel, green, with pale commissures, lobes narrowly lanceolate, 5–7 mm, margins narrow, membranous, apex acuminate;

corolla white to pale yellow, sometimes purple tinged, clawed, ca. 2 times calyx, claw longer than calyx, broadened into obtriangular limb, limb 5–8 mm, cleft ca. to middle into (2–)4–8 lanceolate to oblong lobes, appendages 2, very short;

stamens exserted, shorter than petals;

styles 3, exserted, slender, shorter than petals.

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

carpophore 1–2.5 mm.

narrowly ovoid, equaling calyx, opening by 3 teeth that tardily split into 6;

carpophore 3–6 mm.

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

brown, broadly reniform, flattened, ca. 1.5 mm, sides rugose, margins papillate;
