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

erect, simple to sparingly branched, leafy, 20–70 cm, glabrous to puberulent, especially distally.

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, sessile or short-petiolate, largest near mid-stem region, reduced and withering proximally, blade elliptic-lanceolate, base cuneate or rounded, apex gradually acuminate and acute, glabrous to puberulent.

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

cymose, (1–)3–5(–12)-flowered, open, leafy.

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

1/2–21/2 times calyx, apex often becoming deflexed, glabrous to hirsute.

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 green, obscurely 10-veined, broadly tubular to campanulate, ± constricted at base around carpophore with broad umbilicate base, becoming broadly clavate in fruit, 14–17 × 5–9 mm, herbaceous, glabrous or hirsute, veins green, without pale commissures, lobes triangular, 2–3 mm;

corolla white, clawed, claw equaling calyx, expanded distally into 2-lobed limb, limb oblong, 6–7 mm, appendages oblong, 1–1.6 mm, margins ± entire;

stigmas 3, short-exserted.

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

carpophore 1–2.5 mm.

globose, equaling calyx, opening by 3 broad teeth that sometimes split to form 6;

carpophore 5–6 mm.

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