Flora of North America species comparison

ascending, decumbent at base, branched, shortly rhizomatous, to 80 cm, softly pubescent, ± glandular, at least distally, rarely subglabrous.

erect, branched distally, with 2–4 pairs of reduced leaves, 15–50 cm; flowering shoots usually subscapose, coarsely pubescent with hairs colorless, septate, and long, viscid-glandular, especially 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 long-petiolate, blade oblanceolate to elliptic, 6–15 cm × 10–30 mm, narrowed to base, not fleshy;

cauline few, sessile, reduced distally, blade lanceolate, 0.8–4 cm × 3–8 mm, not fleshy.

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.

thyrsate, subscapose, rarely simple, (3–)5–12(rarely more)-flowered, open, bracteate, bracteolate, densely pubescent, glandular, viscid; alternate branches often suppressed or developing unevenly;

proximal nodes often with single flower;

bracts and bracteoles resembling stem leaves but much reduced.

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

1/4–2 times length of calyx.

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, veins parallel, those of lobes broadened distally, tubular in flower, 10–13 × 2.5–4 mm, campanulate-ovate in fruit, broadest near middle and contracted towards mouth, not contracted proximally, 12–18 × 5–8 mm, with pale commissures, lobes 5, erect, narrowly lanceolate, 4–6 mm, margins narrow, membranous proximally, apex blunt, with glandular hairs;

petals 11/2–2 times longer than calyx tube;

corolla pink, clawed, claw equaling calyx tube, limb obovate, deeply 2-lobed, 5–10 mm, appendages 2, linear, ca. 1.5 mm;

stamens exserted, shorter than petals;

styles 3–5, included in calyx, ± equaling calyx or corolla.

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

carpophore absent.

conic to ellipsoid, equaling calyx lobes, opening by 6–10 recurved teeth;

carpophore 1–2 mm.

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

dark brown, reniform, 1–1.5 mm, prominently papillate;

papillae larger around margins.
