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.

ascending, scarcely branched, 8–20(–30) cm, softly pubescent, stipitate-glandular or eglandular, rarely glabrate.

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.

mostly basal, petiolate, 3–12 cm (including petiole);

cauline leaves in 2–4 pairs, those of mid and distal stem sessile, shorter and narrower;

blade narrowly to broadly oblanceolate, base spatulate into winged petiole, apex acute to obtuse, glabrous, puberulent or pilose on both surfaces and frequently stipitate-glandular, at least petioles usually ciliate.

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

(1–)3–15-flowered, open, bracteate;

bracts foliaceous.

ascending or erect, 0.2–0.8(–1.5) cm, densely pubescent and frequently stipitate-glandular.

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 usually green, prominently 8–10-veined, in flower narrowly tubular, lobed, narrowed proximally around carpophore, 15–22 × to 5 mm, becoming broader and clavate in fruit, pilose or stipitate-glandular, veins parallel, with pale commissures, lobes round, 1–3 mm, margins usually purple tinged, broad, membranous;

petals spreading, usually bright pink, rarely white, broadly to narrowly obovate, 2 times longer than calyx, base tapered into ciliate claw equaling or slightly longer than calyx, margins entire or shallowly lobed and crenulate, auricles absent, appendages oblong, unlobed, 1.5–2 mm;

stamens equaling claw;

filaments glabrous;

styles 3(–4), ultimately slightly exceeding claw.

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

carpophore shorter than 1 mm, pubescent.

ellipsoid to obovoid, 8–10 mm, equaling calyx, opening by 6 (or 8) recurved teeth;

carpophore 5–8 mm.

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

dark brown, reniform-rotund, 1.3–1.5 mm, coarsely and evenly papillate.
