Flora of North America species comparison

usually several–many, rarely 1, erect, leafy, 10–55 cm, base often decumbent with marcescent leaf bases, scabrous-puberulent to pubescent, usually ± viscid-glandular distally, rarely densely so.

1–several, straggling to erect, sometimes decumbent at base, simple or much-branched distally, 20–120 cm, puberulent or scabrous-pubescent, sometimes retrorse, often glandular distally, becoming glabrate proximally.

2 per node;

basal petiolate, blade linear-lanceolate to lanceolate, 3–10 cm × 2–13 mm (including petiole), apex acute, glabrous to scabrous-puberulent or softly pubescent, petiole often ciliate;

cauline sessile or petiolate, connate proximally, reduced distally, blade linear to narrowly lanceolate, 2–10 cm × 2–8 mm.

sessile or narrowed at base into pseudopetiole, blade pubescent on both surfaces;

proximal with blade lanceolate and oblanceolate, broadest distally or distal often reduced, cauline longest near mid stem, blade linear to lanceolate or elliptic, 1.5–10 cm × 2–30 mm.

cymose with elongate ascending branches, open, flowers (1–)3 to many, bracteate, bracteolate;

bracts and bracteoles lanceolate, 3–20 mm, apex acuminate.

from 1-flowered to simple dichotomy to compound and 3–5–many-flowered with elongate branches;

bracts small, linear-lanceolate, or resembling leaves.

1/4–3 times longer than calyx, scabrous-puberulous to pubescent and glandular, ± viscid.

elongate, much exceeding calyx.

calyx prominently 10-veined, tubular in flower, ± clavate and contracted around carpophore in fruit, 10–14 × 4–6 mm, margins dentate, veins parallel, green (rarely purplish), with pale commissures, lobes ascending, lanceolate, 2–3 mm, margins usually with obtuse, membranous border, apex spreading, shortly glandular-pubescent, usually viscid;

corolla off-white (greenish) to dusky pink, clawed, claw equaling calyx, limb obovate, 2-lobed, 3–7 mm, shorter than claw, rarely with small lateral teeth, appendages 2, usually lacerate, 1–2 mm;

stamens ca. equaling petals;

styles 3(–4), often much longer than petals.

calyx green, 10-veined, broadly tubular, 12–25 × 4–8 mm in flower, narrower towards base, middle broadening to 6–13 mm in fruit, narrower at both ends, pubescent, glandular, lobes lanceolate, 2.5–5 mm, margins membranous or not, apex ± obtuse;

corolla scarlet, clawed, claw equaling or longer than calyx, limb lobed, often deeply so, lobes 4–6, linear, lanceolate, or oblong, small lateral teeth may be present, 6–15 mm, appendages inconspicuous, 1–2 mm, dentate;

stamens longer than corolla claw but shorter than lobes;

stigmas 3, equaling corolla.

ovoid-ellipsoid, slightly longer than calyx, opening by 6 (or 8) recurved teeth;

carpophore 2–5 mm.

oblong to ovoid or broadly tubular, equaling calyx, opening by 6 ascending teeth;

carpophore 2–4 mm.

dark reddish brown to black, reniform, ca. 1.5 mm, papillate, with larger papillae around margins.

reddish brown, broadly reniform, 1.7–2.3 mm, sides tuberculate, margins papillate.
