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

sessile at mid and distal stem, petiolate to spatulate proximally;

petiole equaling or longer than blade of basal leaves;

blade ovate to elliptic, 3–13 cm × 10–50 mm (not including petiole), apex acute to acuminate, sparingly pubescent, densely so on abaxial midrib.

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.

dichasial cymes, several- to many-flowered, open, bracteate;

bracts lanceolate, 4–20 × 2–7 mm, herbaceous, softly hairy throughout with long-septate hairs, not glandular, or with some glandular hairs.

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

ascending, 0.2–3 cm, usually shorter than calyx.

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

unisexual, some plants having only staminate flowers, others having only pistillate flowers, 20–25 mm diam.;

calyx 8–12-veined, campanulate, narrowly so in staminate flowers, broadly in pistillate, 10–15 × to 7 mm in flower, 11 mm broad in fruit, herbaceous, margins dentate, softly pubescent, lobes 5, erect, lanceolate, 2–3 mm;

petals bright pink, clawed, claw equaling or longer than calyx, limb spreading horizontally, broadly obovate, unlobed or 2-lobed, to 12 × 12 mm, appendages 4, ca. 1 mm;

stamens and stigmas equaling petal claw;

styles 5.

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.

broadly ovoid to globose, equaling and often splitting calyx, opening by 5 (splitting into 10) revolute teeth;

carpophore absent.

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

carpophore 1–2.5 mm.
