Flora of North America species comparison

erect, branched, rarely simple, 15–45 cm, with long, often crinkled hairs mixed with short pubescence, viscid-glandular distally.

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, blade with coarse, ascending, scabrous pubescence on both surfaces;

basal few, withering, blade oblanceolate to spatulate-petiolate, 0.5–5 cm × 3–15 mm;

cauline blades oblanceolate to lanceolate, 1–7 cm × 1–15 mm, apex obtuse or shortly acuminate to acute.

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.

open, with racemose branches, internodes and bracts usually ca. equaling fruiting calyx, 1–5 mm, longer proximally.

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

bracts small, linear-lanceolate, or resembling leaves.

elongate, much exceeding calyx.

5–8 mm diam.;

calyx prominently 10-veined, narrowly tubular-ovoid in flower, ovoid in fruit, constricted at mouth, 7–10 × 3–5 mm, membranous between veins, margins dentate, hispid, hairs ca. 2 mm, veins parallel, lobes lanceolate, 2–2.5 mm, apex greenish purple, acute;

petals white or pink, often with dark spot or dark pink throughout, clawed, claw equaling calyx, limb elliptic to obovate, lobed or unlobed, to 6 mm, appendages 2, oblong to narrowly lanceolate, 1–1.5 mm;

stamens equaling or shorter than calyx;

stigmas 3, included in calyx.

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.

equaling calyx, opening with 6 recurved, narrowly triangular teeth;

carpophore shorter than 1 mm, pubescent.

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

carpophore 2–4 mm.

dark reddish brown, reniform, angular with concave, radially ridged faces, broad outer edge transversely ridged and verrucose, ca. 0.5 mm broad.

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