Flora of North America species comparison

numerous, erect, simple, 3–15 cm, pubescent, viscid-glandular distally.

erect, branched distally, with 2–4 pairs of reduced leaves, 15–50 cm; flowering shoots usually subscapose, coarsely pubescent with hairs colorless, septate, and long, viscid-glandular, especially distally.

mostly basal, densely tufted;

basal numerous, pseudopetiolate, blade narrowly oblanceolate, tapering into base, 0.5–3 cm × 1.5–4 mm, ± fleshy, apex acute, puberulent;

cauline in 1–3 pairs, ± sessile, reduced, blade narrowly oblanceolate to linear-lanceolate, 0.7–2 cm × 1–3 mm, apex acute, puberulent.

mostly basal;

basal long-petiolate, blade oblanceolate to elliptic, 6–15 cm × 10–30 mm, narrowed to base, not fleshy;

cauline few, sessile, reduced distally, blade lanceolate, 0.8–4 cm × 3–8 mm, not fleshy.

flowers terminal, solitary, or in single dichotomy, bracteate;

bracts leaflike, 3–15 mm.

thyrsate, subscapose, rarely simple, (3–)5–12(rarely more)-flowered, open, bracteate, bracteolate, densely pubescent, glandular, viscid; alternate branches often suppressed or developing unevenly;

proximal nodes often with single flower;

bracts and bracteoles resembling stem leaves but much reduced.

erect, ca. equaling calyx, viscid glandular-pubescent, hairs with purple septa.

1/4–2 times length of calyx.

calyx prominently 10-veined, campanulate, not contracted proximally around carpophore, 10–15 × 5–7 mm, papery, veins parallel, purplish, with pale commissures, with purple-septate glandular hairs (rarely septa not purple), lobes ovate, ca. 2 mm, margins broad, membranous, apex obtuse;

corolla off-white or tinged with dusky purple, clawed, claw equaling calyx, broadened distally, limb 2-lobed, 3–5 mm, appendages ca. 1 mm;

stamens equaling calyx;

styles 3(–4), equaling calyx.

calyx prominently 10-veined, veins parallel, those of lobes broadened distally, tubular in flower, 10–13 × 2.5–4 mm, campanulate-ovate in fruit, broadest near middle and contracted towards mouth, not contracted proximally, 12–18 × 5–8 mm, with pale commissures, lobes 5, erect, narrowly lanceolate, 4–6 mm, margins narrow, membranous proximally, apex blunt, with glandular hairs;

petals 11/2–2 times longer than calyx tube;

corolla pink, clawed, claw equaling calyx tube, limb obovate, deeply 2-lobed, 5–10 mm, appendages 2, linear, ca. 1.5 mm;

stamens exserted, shorter than petals;

styles 3–5, included in calyx, ± equaling calyx or corolla.

equaling calyx, opening by 6 (or 8) teeth;

carpophore 2.5–3.5 mm.

conic to ellipsoid, equaling calyx lobes, opening by 6–10 recurved teeth;

carpophore 1–2 mm.

brown, broadly winged, reniform, 1–2 mm, rugose-tessellate.
