Flora of North America species comparison

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.

decumbent to erect, simple or branched, leafy throughout, 5–30(–70) cm, usually glandular-puberulent distally, proximal pubescence varying from short and sparse to multicellular, crinkled and deflexed, glandular or not.

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.

2 per node, sessile or short-petiolate;

blade usually oblanceolate to elliptic-lanceolate, rarely obovate or elliptic, 2–6(–10) cm × 3–20(–35) mm, broadest at or above middle, narrowed to base, margins ciliate with short, somewhat scabrid hairs, apex acute to acuminate, puberulent to pubescent.

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.

cymose, or flowers axillary or solitary and terminal;

cyme loose, compound, leafy.

1/4–2 times length of calyx.

slender, 0.5–3 cm, glandular-puberulent.

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.

functionally unisexual, usually bisexual;

calyx obscurely 10-veined, campanulate, 5–8 mm, ca. 1/2 as wide, herbaceous, margins dentate, lobes lanceolate, 1.5–3 mm, apex recurved, subacute to acuminate, puberulent to pilose and glandular, veins without conspicuous, pale commissures;

corolla white, clawed, 1–11/2 times calyx, claw shorter than calyx, limb oblong, 2-lobed, 1.5–3 mm, lobes oblong, apex obtuse, appendages 2, small, 0.1–0.4 mm;

stamens in functionally staminate flowers equaling corolla, otherwise reduced and included in calyx;

stigmas 3(–4), equaling corolla in functionally pistillate flowers, otherwise included in calyx, papillate along whole length.

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

carpophore 1–2 mm.

green, becoming black, ovoid-ellipsoid, slightly longer than calyx, opening by 3 erect teeth which often split into 6;

carpophore ca. 1.5 mm.

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

papillae larger around margins.

black, not winged, broadly reniform, 0.5–1 mm, glossy, obscurely reticulate.
