Flora of North America species comparison

erect or ascending, sparingly branched throughout, 30–70 dm, densely glandular-villous, or glandular-puberulent, with spreading, nonglandular hairs basally, glabrous distally.

usually erect or ascending, occasionally decumbent, sparingly branched throughout, 2–5(–9) dm, hirsute, puberulent, or glandular basally, hair types often mixed, glandular-puberulent, glabrous, or occasionally puberulent and sparsely hispid distally.

mostly in basal 1/2;

larger leaves with petiole 10–30 mm, blade oval, oblong, ovate, or ± triangular, 18–45 × 13–30 mm (distal leaves usually smaller, sometimes longer, proportionately narrower), adaxial surface lightly to densely glandular-pubescent, abaxial surface paler than adaxial, lightly to densely glandular-pubescent, neither surface punctate or both minutely punctate with clusters of brown cells, base truncate, round, or obtuse, margins sinuate, sometimes crisped, apex round to obtuse, rarely acute.

mostly in basal 2/3 of plant;

larger leaves with petiole 1–5 mm, blade lanceolate to linear, rarely ovate, 15–35 × 1–15 mm (distal leaves usually longer, narrower), adaxial surface glabrous or sparsely hispid, occasionally glandular-pubescent, sometimes punctate, abaxial surface usually paler than adaxial, glabrous or sparsely hispid, occasionally glandular-pubescent, usually punctate with small patches of large gray to dark brown cells, base obtuse, truncate, or rounded, margins entire and revolute, apex usually acute, sometimes obtuse or rounded.

terminal and axillary, branched 1–4 times unequally, with sticky internodal bands;

branches strongly ascending, terminating in spicate or racemose flower clusters, axis 10–55 mm.

terminal and axillary, forked ca. 2–4 times unequally, open, without sticky internodal bands;

branches strongly ascending, terminating in loose, 1–few-flowered, cymose clusters.

pedicel 0.4–2.3[–3.7] mm;

bracts at base of perianth usually soon deciduous, usually 2, narrowly to broadly lanceolate, 0.7–1.8 mm, apex often acuminate;

perianth white to pale pink, campanulate distal to constriction, 1–1.3 mm;

stamens (2–)3, slightly exserted or included.

pedicel 1–2(–5) mm;

bracts at base of perianth persistent, 3, lanceolate to ovate-acuminate, 1–2 mm;

perianth purplish pink, widely funnelform beyond constriction, 4–7 mm;

stamens 5(–6), well exserted.

5–33 per cluster, usually overlapping or 2–4 in group separated by small gap from next group, straw colored to grayish or reddish tan, broadly obovoid, 1.9–2.4(–2.8) × 1.1–1.3 mm (l/w: 1.7–2.1[–2.3]), apex rounded, glabrous;

ribs 5, obtuse-rounded to obtuse, often with low winglike ridge, slightly rugose near sulci;

sulci (0.2–)0.5 times as wide as base of ribs, slightly rugose, not papillate.

borne singly (or 2–3 in open clusters), dark gray-brown, oblong-clavate, 2.5–3.5 × 1.2–1.5 mm (l/w: (1.7–)2.1–3.5), apex round, usually glabrous;

ribs (4–)5, broadly rounded, smooth, edges sharp and slightly overhanging sulcus;

sulci about as wide as base of ribs, smooth, not papillate (very rarely minutely and sparsely puberulent).
