Flora of North America species comparison

erect, 5–40 cm, softly pubescent to scabrous, eglandular or viscid-glandular, especially distally, very rarely glabrous, with several pairs of leaves equaling or shorter than internodes.

not much- branched, slender, (15–)30–60 cm, sparsely pubescent proximally, viscid-glandular distally.

sessile, or basal with short pseudopetiole;

blade linear to lanceolate or broadly ovate, base round to cuneate, apex acute to shortly acuminate, puberulent on both surfaces, sometimes glandular.

mostly basal;

blade linear-lanceolate to oblanceolate, 2–8 cm × 2–6(–15) mm (including petiole), base tapered into slender petiole, apex acute to obtuse, subglabrous to glandular-pubescent on both surfaces;

cauline leaves to 4 pairs below inflorescence, narrower than basal leaves, blade usually linear but rarely elliptic-lanceolate.

usually with single dichotomy, rarely double, open, bracteate, branches often elongate, flowers 1 per node;

bracts foliaceous.

erect, with several short, ascending branches, few-flowered, open, bracteate, shortly pubescent and viscid-glandular;

bracts narrowly lanceolate, 3–10 mm, rigid.

sharply reflexed at base, especially after anthesis, equaling calyx.

nodding;

calyx obscurely 10-veined, broadly campanulate, lobed, 6–8 mm, enlarging to 13–16 mm in fruit, herbaceous, usually with short, dense pubescence throughout, often glandular-viscid, veins green, rarely purplish tinged, conspicuous pale commissures absent;

lobes ovate-triangular, 1/2 to equaling tube, herbaceous;

petals creamy white, often greenish abaxially, rarely pink tinged to dusky pink (subsp. campanulata), clawed, to 2 times calyx, claw villose, limb deeply divided and fan-shaped with many narrow, linear lobes, lobes rapidly curling, margins deeply divided or erose, appendages 2–4, to 2 mm;

stamens exserted;

filaments hairy at base;

styles 3, to 2 times calyx.

calyx prominently 10-veined, broadly tubular, umbilicate, moderately or not clavate, narrowed around carpophore, lobed, 12–15 × 4–6 mm, thin and papery, with short glandular-viscid pubescence, veins parallel, usually red pigmented, with pale commissures;

lobes lanceolate, 2–4 mm, apex acute;

petals white, pink, or dingy red, 11/2–2 times calyx, claw equaling calyx, ciliate at base, limb obtriangular, 4–6 mm, deeply divided into 4 linear lobes, appendages 2, conspicuous, laciniate, 2–3 mm, apex rounded;

stamens slightly exserted;

filaments ciliate at base;

styles 3(–4), equaling or longer than stamens.

ovoid, ca. equaling calyx and often splitting it, opening by 6 broadly triangular teeth;

carpophore 1–2.5 mm.

1-locular, narrowly ovoid, exceeding calyx, opening by 6 (or 8) ascending teeth;

carpophore 3–6 mm.

brown, reniform, 2–2.5 mm broad, coarsely and ± evenly papillate;

papillae ca. as long as broad.

brown, reniform, 1.5–2 mm broad, shallowly tuberculate on both surfaces, papillate around margins.
