Flora of North America species comparison

many, ascending, often sigmoidally bent, nodding distally, later erect, clumped or mat-forming, terete, 3–20(–25) cm, simple, subglabrous, sometimes with faint raised strigillose lines decurrent from margins of petioles, rarely mixed strigillose and sparsely glandular puberulent distally.

erect to ascending, often clumped but not matted, green or gray-green, terete, 10–110(–120) cm, usually well-branched throughout, sometimes simple, strigillose and/or long-villous, usually mixed glandular puberulent distally, rarely glabrate.

opposite and crowded proximal to inflorescence, alternate distally, petioles 1–6 mm, rarely subsessile distally;

blade spatulate to oblong proximally, elliptic to narrowly lanceolate or sublinear distally, (0.5–)0.8–2.5 × 0.3–1 cm, base attenuate to cuneate, margins subentire proximally, sparsely denticulate distally with 2–5 low teeth per side, veins obscure, 2–4 per side, apex obtuse or rounded proximally to subacute distally, surfaces subglabrous;

bracts reduced, usually much narrower.

± densely spaced, alternate and often fasciculate distally, subsessile, blade grayish green or green to silvery-canescent, usually narrowly linear to lanceolate or elliptic to ovate, rarely orbiculate, 0.6–5(–6) × 0.1–2.5 cm, base cuneate to attenuate, margins subentire to sharply toothed, 3–15 teeth per side, veins inconspicuous or prominent, 3–7 per side, apex acute, sometimes with caducous dark mucro, surfaces usually ± densely strigillose, sometimes mixed villous and/or glandular puberulent, rarely glabrate;

bracts much smaller and narrower.

nodding in bud, later suberect, few-flowered racemes, subglabrous to sparsely strigillose and/or glandular puberulent.
