Flora of North America species comparison

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

erect or ascending, unbranched in small plants to ca. 1–5 times branched throughout, 20–60 dm, densely glandular-pubescent throughout.

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.

mostly in basal 1/2;

larger leaves with petiole 5–35 mm, blade ovate-triangular, ovate, or broadly lanceolate, 15–55 × 7–35 mm (distal leaves smaller, proportionately narrower), adaxial surface usually pubescent, often glandular, sometimes glabrate but with hairs along midrib, abaxial surface similar, somewhat paler, both surfaces often finely punctate with groups of brown cells, base usually round to obtuse, occasionally subtruncate, margins ± sinuate, apex acute, occasionally obtuse.

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).

terminal, branched ca. 1–4 times unequally, without sticky internodal bands;

branches strongly ascending, terminating in spicate or racemose flower clusters, axis 10–35 mm.

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.

pedicel 0.3–0.7 mm;

bracts at base of perianth persistent, 1–2, ovate-acuminate, 1.5–4 mm;

perianth whitish to pale pink (rarely golden yellow), campanulate distal to constriction, 1.2–1.4 mm;

stamens 2–3, included or barely exserted.

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.

4–15 per cluster, well spaced to completely overlapping, straw colored to tan at maturity, broadly obovoid, 2.1–2.5 × 1–2 mm (l/w: 1.3–2.1), apex rounded, glabrous;

ribs 4(–5), broadly acute, never winged, slightly rugose adjacent to sulci;

sulci 0.5–1 times as wide as base of ribs, coarsely transversely rugose, not papillate.
