Flora of North America species comparison

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

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.

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.

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.

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

cymose, or flowers axillary or solitary and terminal;

cyme loose, compound, leafy.

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

slender, 0.5–3 cm, glandular-puberulent.

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.

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.

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

carpophore 1–2.5 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.

brown, broadly reniform, flattened, 2–2.5 mm, rugose, more coarsely so on margins.

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