Habit | Plants 60–120 cm; caudices thick, woody, roots thick. | Plants 30–100 cm; caudices branching; vascular bundles and petiole bases persistent (attached to old stems for more than a season). |
Stems | 1–5+, sparsely to moderately short strigose or villous. |
1–10+, ascending-erect, glabrous proximally, usually moderately scabrous-puberulent distally. |
Leaves | basal withering by flowering, petiolate, smaller to much smaller than cauline, blades oblanceolate, margins serrate; cauline sessile, blades elliptic-lanceolate or -oblanceolate, mid 80–140 × 2.5–4 mm, distally reduced, usually membranous, bases tapering, attenuate, margins sharply toothed along much of length to nearly entire, ciliate, abaxial faces short-pilose along small and large nerves, adaxial short-pilose along larger nerves. |
basal often present at flowering as new rosettes; basal and proximal cauline often with distal portions withering by flowering, long-petiolate, blades shiny, ± 3-nerved, linear to oblanceolate, (30–)100–250 × (2–)5–15 mm, margins entire or sparsely serrulate, faces glabrous; mid and distal cauline sessile, blades linear-lanceolate to linear, 15–80 × 1–7 mm, much reduced distally, faces glabrous or scabrous. |
Peduncles | 1–6 mm, moderately canescent; bracteoles linear to lanceolate. |
usually moderately to densely strigillose, sometimes sparsely so or glabrous; bracts minute. |
Involucres | campanulate, 4.5–5.5 mm. |
campanulate, 4.5–6 mm. |
Ray florets | 6–8; laminae 3–4 × 1–1.5 mm wide. |
1–4; laminae 3–5 × 1–1.5 mm. |
Disc florets | 8–14; corollas 4–5 mm, lobes ca. 1.5 mm. |
7–13; corollas 4–5 mm, lobes 0.5–1 mm. |
Phyllaries | in ca. 3 series, strongly unequal, erect to slightly squarrose-tipped, lanceolate, apices acute, glabrate, sparsely to moderately, finely stipitate-glandular. |
in 3–4 series, broadly oblong, unequal, firm, striately nerved, rounded, glabrous. |
Heads | 5–160 (2–10+ more per short branch cluster), in narrowly elongate paniculiform arrays, branches usually 1–6 cm (much longer in damaged plants, sometimes 1–3 proximal branches much elongated in undamaged plants), ascending and bearing short terminal racemiform or paniculiform clusters. |
20–150+ in compactly corymbiform arrays, sometimes somewhat rounded. |
Cypselae | (reddish brown) 2–3 mm, glabrous; pappi 4–5 mm. |
(dark brown, obconic, full) 2–3 mm (7–10 nerved), glabrous; pappi 4–5 mm (clavate). |

Discussion | Solidago buckleyi is an uncommon species of mesic woods, most variable in the size and number of teeth on the large mid cauline leaves. Once seen, usually it is not easily confused with S. petiolaris. Reports from farther east are for plants of S. petiolaris.
