Flora of North America species comparison

prostrate to decumbent, usually profusely branched throughout, 3–15 dm, minutely pubescent, often glandular, sometimes spreading villous or hirsute in basal portions, minutely pubescent, sometimes glandular, glabrate, or glabrous distally.

usually erect, sometimes decumbent, profusely branched primarily distally, 2–12 dm, minutely puberulent with bent hairs basally, usually glabrous, rarely sparsely puberulent distally.

usually distributed throughout plant and into much of inflorescence;

larger leaves with petiole 5–25 mm, blade broadly lanceolate, ovate, or broadly ovate, occasionally ± round, 20–70 × 10–60 mm (distal leaves smaller, often proportionally narrower), base truncate, broadly cuneate, or round, rarely cordate, margins sinuate, apex acute to obtuse or round, adaxial surface glabrous or sometimes sparsely puberulent, rarely densely glandular-pubescent, abaxial surface paler than adaxial surface, glabrous or sometimes sparsely puberulent, rarely densely glandular-pubescent, often with large multicellular hairs along veins, neither surface punctate.

mostly in basal 1/2 of plant;

larger leaves with petiole 6–40(–55) mm, blade broadly rhombic-ovate, triangular-ovate, ovate, oval, or lanceolate, 20–50(–80) × 10–45 mm (distal leaves smaller, proportionately narrower), adaxial surface usually glabrous, sometimes minutely puberulent, usually minutely punctate, abaxial surface slightly paler than adaxial, usually glabrous, sometimes minutely puberulent, usually punctate with small patches of small brown cells, base obtuse to round, margins entire or sinuate, apex usually acute, less often obtuse or rounded.

axillary or terminal, forked unequally ca. 3–6 times, open, without sticky internodal bands;

branches divergent, terminating in compact subumbellate or capitate 5-flowered clusters.

terminal, forked ca. 4–6 times ± evenly, diffuse, usually with sticky internodal bands;

branches strongly ascending, terminating in irregular umbellate or subracemose clusters of flowers, not all pedicels attaching at same point (flowers occasionally borne singly).

pedicel shorter than 0.5 mm;

bract at base of perianth usually quickly deciduous, 1, linear-lanceolate to ovate, 0.5–1 mm;

perianth maroon, or magenta (or rarely white or yellow) [pink], campanulate beyond constriction, 1–3.5 mm;

stamens 2–3, slightly exserted.

pedicel (0–)0.3–2.5(–5) mm;

bracts at base of perianth deciduous, usually 2, narrowly to broadly lanceolate, 0.5–1 mm, apex often acuminate;

perianth whitish, usually tinged with pink or purple [bright pink] between lobes and in tube, campanulate beyond constriction, 1–1.5 mm;

stamens 2–4, slightly exserted.

(2–)5–20(–30) per cluster, gray-brown to brown, narrowly obovate and tapering at both ends or clavate, 2.6–4 × 0.9–1.2 mm (l/w: 2.7–3.5), apex rounded to rounded-conic, moderately densely to densely stipitate-glandular on ribs and in sulci;

ribs 5, rounded, smooth;

sulci 1–2.5 times as wide as base of ribs, not rugose, not papillate.

1–11 per cluster, pale greenish to straw colored or tan, narrowly obconic, (2.7–)3–3.5[–4] × 1.2–1.5 mm (l/w: (2–)2.3–3.2), apex truncate or broadly low conic, glabrous;

ribs 5, acute, slightly rugose adjacent to sulci;

sulci 0.5–1 times as wide as base of ribs, slightly to prominently coarsely transverse rugose, not papillate.
