Flora of North America species comparison

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

many, decumbent to erect, usually simple, 10–40 cm, woody, pilose and glandular (rarely eglandular proximally).

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.

in 5–8 pairs, sessile but proximal ones narrowed into pseudopetiole, largest in mid-stem region, reduced proximally, scalelike at base, blade narrowly lanceolate to oblanceolate-elliptic or obovate, 2–6 cm × 3–20 mm, apex acute and acuminate, usually thick, leathery, densely puberulent and viscid-glandular or eglandular.

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.

cymose, open or congested, 3–15(–30)-flowered, sometimes compound, leafy.

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

to 1(–1.5) cm, shortly pilose, viscid-glandular, flowers sometimes sessile.

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, tubular, clavate in fruit, constricted proximally around carpophore, (20–)25–30 × 4–7 mm, papery, densely glandular-puberulent, viscid, veins parallel, green, with pale commissures, lobes narrowly lanceolate, acuminate, 5–8 mm, herbaceous;

corolla pale greenish yellow to white, clawed, claw equaling calyx, ligulate, as broad as limb, limb 7–8 mm, deeply laciniate into 6 or more linear lobes, appendages oblong, laciniate, 2 mm;

stamens equaling calyx;

styles 3, exserted.

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

carpophore absent.

equaling calyx, opening by 6 ascending teeth;

carpophore ca. 3 mm.
