Plants 30–200 cm; rhizomes long-creeping, forming clones. Stems 1–50+, erect, glabrous or densely hispid to strigose. Leaves: basal withering by flowering; proximal cauline usually withering by flowering, sessile, blades elliptic to lanceolate, 68–104 × 20–25 mm, margins sharply serrate, apices acute to attenuate, abaxial faces usually hispido-strigose (at least on main nerves), nerves sometimes prominent, abaxial glabrate; mid to distal cauline sessile, blades lanceolate, elliptic or ovate, (15–) 40–75 (–90) × (6–) 12–22 (–32) mm, largest at midstem, somewhat reduced to much reduced distally, margins coarsely to finely serrate, ciliate, indument similar to proximal or denser. Heads 50–1500, secund, in secund-pyramidal paniculiform arrays 7–36 (–50) × 9–26 cm, compact to lax, branches divergent and recurved, longest 0.8–34 cm, leafy-bracteate. Peduncles 1–1.8 mm, sparsely to densely hispido-strigillose; bracteoles linear-lanceolate to ovate. Involucres narrowly campanulate, (2–) 2.5–3.5 (–4.5) mm. Phyllaries in 3–4 series, strongly unequal, lanceolate to linear-lanceolate, acute to obtuse. Ray-florets (4–) 6–8 (–12); laminae (0.9–) 1–1.6 (–2.3) × 0.4–0.7 mm. Disc-florets (2–) 4–6 (–8); corollas 2–3.5 (–4.5) mm, lobes (0.5–) 0.7–1 (–1.3) mm. Cypselae (narrowly obconic) 0.9–1.5 mm, moderately strigillose; pappi 1.8–2.5 mm.

Discussion

Subspecies 2 (2 in the flora).

Solidago rugosa is highly variable in size, array shape, and hairiness. It is similar to members of the S. canadensis complex; it differs in not having 3-nerved leaves. The species is divided into two subspecies and five varieties that can be difficult to distinguish.
