Flora of North America species comparison

several, simple proximal to inflorescence, 30–80 cm, puberulent, becoming subglabrous near base.

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

withering proximally, in whorls of 4, ± sessile to short-petiolate, largest in mid-stem region;

blade lanceolate to ovate-lanceolate, 3–10 cm × 4–40 mm, apex acuminate, puberulent on both surfaces, sparsely so adaxially.

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.

paniculate, open, bracteate, bracteolate, branches elongate, puberulent;

bracts and bracteoles linear-lanceolate, 2–15 mm.

(1–)3–15-flowered, open, bracteate;

bracts foliaceous.

straight, often with 1 or 2 pairs of bracteoles, slender, 1/2–3 times calyx, glabrous or scabrous-puberulous.

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

calyx obscurely 10-veined, broadly campanulate, becoming obtriangular in fruit, 7–11 × 6–10 mm, herbaceous, margins dentate, very narrow, membranous, sparsely puberulent, lobes broadly triangular, 2–3 mm;

corolla white, ca. 2 times longer than calyx, limb obtriangular, narrowed into claw, divided ca. 1/2 its length into 4–12 lobes, appendages absent;

stamens equaling petals;

styles 3, longer than petals.

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.

globose, opening by 3 broadly triangular teeth;

carpophore 2–3 mm.

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

carpophore 5–8 mm.

dark brown, reniform, ca. 1 mm, papillate.

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