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

erect, simple proximal to inflorescence or with few basal branches, branched distally, to 75 cm.

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, gradually reduced distally;

basal blades oblanceolate, 6–12(–14) cm × 20–45 mm;

cauline blades ascending, conspicuously veined, broadly elliptic to lanceolate, 1–11 cm × 3–40 mm, apex acute, shortly acuminate, densely pubescent on both surfaces.

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

cymose, 3–15-flowered, bracteate;

cyme open, flowers held on ascending branches;

bracts leaflike, narrowly lanceolate, 1–5 cm, apex acuminate.

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

ascending, straight, 1/3–3 times longer than 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.

nocturnal, 20–25 mm diam.;

calyx prominently 10-veined, ovate-elliptic, fusiform, narrowed to both ends and constricted around carpophore, 15–24(–40) × ca. 3 mm in flower, swelling to 10 mm diam. in fruit, thin and papery, margins dentate, with pale commissures;

lobes erect, often recurved in fruit, linear-lanceolate, long, narrow, (3–)5–10(–15) mm, apex acuminate, short-pubescent, glandular, interspersed with long eglandular hairs, veins anastomosing;

corolla white, often pink tinged, clawed, claw equaling calyx lobes, limb deeply 2-lobed, lobes usually narrow, appendages 0.5–1.5 mm broad, margins entire or erose;

stamens shorter than petals;

styles 3, shorter than petals.

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

carpophore 1–2.5 mm.

ovoid, constricted at mouth, equaling or slightly longer than calyx tube, opening by 6 recurved teeth;

carpophore 1–3 mm.

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