Buckley's goldenrod
autumn goldenrod, false goldenrod, limestone goldenrod
1–5+, sparsely to moderately short strigose or villous.
usually 1, ascending to erect or arching, densely spreading-puberulent to occasionally subglabrous.
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 (rosettes) present at flowering, conspicuously petiolate, petioles slightly winged distally, to 100 mm, blades cordate, 40–120 × 40–110 mm, margins coarsely sharp-serrate, apices acute to acuminate, abaxial faces moderately to densely spreading-puberulent, adaxial sparsely so or glabrate;
mid and distal cauline progressively reduced, less petiolate, blades ovate to lanceolate, less cordate distally, 40–60 × 20–30 mm, margins finely serrate.
1–6 mm, moderately canescent;
bracteoles linear to lanceolate.
0–1 mm, sparsely hispido-strigose, bracteoles 1–4, lanceolate-ovate, grading into phyllaries.
campanulate, 4.5–5.5 mm.
narrowly campanulate, 3–4.5 mm.
6–8;
laminae 3–4 × 1–1.5 mm wide.
3–6;
laminae ca. 1 × 0.5–0.7 mm.
8–14;
corollas 4–5 mm, lobes ca. 1.5 mm.
3–6;
corollas 2–2.5 mm, lobes 0.75–1.2 mm.
in ca. 3 series, strongly unequal, erect to slightly squarrose-tipped, lanceolate, apices acute, glabrate, sparsely to moderately, finely stipitate-glandular.
in 2–3 series, ovate, strongly unequal, outer somewhat keeled, firm, margins ciliate.
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.
50–250, densely crowded, often subglomerate, in secund paniculiform arrays, proximal branches few, widely spreading, secund, elongate, distal short, recurved.
(reddish brown) 2–3 mm, glabrous;
pappi 4–5 mm.
1–2 mm, sparsely short-strigose;
pappi ca. 0.5 mm (forming many-bristled crown on longer cypselae).

Solidago buckleyi
Solidago sphacelata
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.

The vernacular name false goldenrod comes from the erroneous assignment of the species to the genus Brachychaeta rather than to Solidago, where it belongs.
