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.

terete, 4.5–55 cm, simple or with proximal ascending branches and/or distal branches, ± densely villous and/or strigillose, mixed glandular puberulent distally or glabrescent.

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.

opposite only in proximal pairs, alternate and crowded distally, subsessile, blade narrowly elliptic or lanceolate, 1.2–5 × 0.2–1.2 cm, usually longer than internodes, base cuneate to attenuate, margins subentire or sparsely serrulate, 3–5 teeth per side, veins inconspicuous, 2–7 per side, apex acute, surfaces villous;

bracts same size and shape as leaves.

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

erect spikes, often congested proximally, sometimes nodding in bud, simple, or sometimes sparsely branched, ± densely mixed villous, strigillose, and glandular puberulent.
