Flora of North America species comparison

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.

subscapose, with (1–)2–3(–4) pairs of leaves, 6–25 cm, much reduced above base, retrorsely puberulent, eglandular.

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.

2 per node;

basal blades oblanceolate, spatulate, 1.4–4 cm × 2–5 mm, base ciliate, apex acute, subglabrous to retrorse-puberulent;

cauline shortly connate proximally, blade narrowly oblanceolate to linear-lanceolate, 0.5–3.5 cm × 1–2 mm, apex purple tinged, retrorse-puberulent, often sparsely so.

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.

1–3(–4)-flowered, open.

1/4–2 times length of calyx.

erect, 1–4 times longer than fruiting calyx, retrorsely puberulent, without glandular hairs.

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.

calyx prominently 10-veined, cylindric, becoming narrowly ovoid, not inflated, not contracted proximally around carpophore, 6–11.5 × 3 mm in flower, broadening to ca. 5 mm in fruit, membranous, uniformly puberulent, without glandular hairs, veins parallel, green, with pale commissures, lobes triangular, 1–1.5 mm, margins narrowly membranous, apex purple-tipped;

corolla white, usually flushed with pink or purple towards apex, ligulate to ± oblanceolate, slightly longer than calyx, not clearly differentiated into claw and limb, unlobed to notched, auricles and appendages absent;

stamens equaling calyx;

styles 3, included in calyx.

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

carpophore 1–2 mm.

ellipsoid-ovoid, slightly longer than calyx, opening by 6 ascending teeth;

carpophore ca. 1 mm.

dark brown, reniform, 1–1.5 mm, prominently papillate;

papillae larger around margins.

rust colored, reniform, 0.7–1 mm, margins papillate;

papillae large, inflated.
