erect, simple, (10–)20–60 cm, softly puberulent, viscid-glandular distally.

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.

mostly basal;

basal petiolate, blade oblanceolate, spatulate, 3–8 cm × 2–14 mm, not fleshy, margins shortly ciliate, apex ± acute, glabrous to puberulent on both surfaces;

cauline usually in 2–4 pairs, blade narrowly oblanceolate, lanceolate to linear-lanceolate, 0.2–0.8 cm × 10–80 mm, not fleshy, puberulent on both surfaces, at least distal ones glandular.

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.

(1–)3–7-flowered, open, bracteate;

bracts linear-lanceolate, broadened at base, 2–10 mm.

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

ascending, usually longer than calyx, puberulent, viscid stipitate-glandular.

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, inflated, ± umbilicate, not or only slightly constricted toward base, (10–)12–16 × 7–9 mm in fruit, glandular-pubescent, strongly viscid, veins parallel, purplish, with pale commissures, not much broadened distally, commissural veins slender, forked distally and fused to those of lobes, lobes ovate to broadly triangular with lanceolate midrib, 2–3 mm, margins purple tinged, broad, membranous;

corolla white, often tinged green or purple, clawed, claw equaling calyx, glabrous, broadened distally, limb deeply 2-lobed, rarely 4-lobed, 5–7 mm, lobes with 2 prominent lateral teeth, appendages 2(–4), 1.5–2 mm;

stamens equaling calyx;

stigmas 3(–5), exserted.

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

carpophore absent.

included in calyx, opening by 3(–5) teeth, each tardily splitting into 2;

carpophore 2–3 mm.

dark brown to black, broadly reniform, plump, 1–1.6 mm, densely and evenly papillate.

brown, not winged, broadly reniform and often flattened, 1.5–2.5 mm, rugose to shallowly tuberculate on sides, larger tubercules on margins.
