1–5+, sparsely to moderately short strigose or villous.
basal and proximal cauline tapering to winged petioles, blades broadly oblanceolate to obovate or elliptic, 35–200 (including petioles) × 15–60 mm, margins serrate or crenate, apices acute, faces sparsely to densely hispido-villous, rarely glabrous;
mid and distal cauline sessile, blades elliptic, 15–30 × 5–7 mm, rapidly reduced distally, margins entire.
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.
1.5–2.5 mm, hispido-villous to canescent.
1–6 mm, moderately canescent;
bracteoles linear to lanceolate.
campanulate, 4–6 mm.
campanulate, 4.5–5.5 mm.
6–14;
laminae 1.5–4.5 × 0.5–1 mm.
6–8;
laminae 3–4 × 1–1.5 mm wide.
6–12;
corollas 3–4.5 mm, lobes 0.6–1.2 mm.
8–14;
corollas 4–5 mm, lobes ca. 1.5 mm.
in 3–4 series, appressed, strongly unequal, midribs and tips conspicuously green, margins white, scarious, apices obtuse, glabrous or moderately strigose.
in ca. 3 series, strongly unequal, erect to slightly squarrose-tipped, lanceolate, apices acute, glabrate, sparsely to moderately, finely stipitate-glandular.
8–250+ in usually wand-paniculiform arrays of short axillary and terminal racemiform, non-secund clusters, sometimes proximal branches elongated, ascending and bearing short axillary and terminal racemiform clusters.
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.
(narrowly obconic) 1–2.5 mm, glabrous;
pappi 2.5–4 mm (sometimes distinctly clavate).
(reddish brown) 2–3 mm, glabrous;
pappi 4–5 mm.

Solidago hispida
Solidago buckleyi
Ray floret color can fade with time, both in the field and on dried specimens, making it difficult to distinguish Solidago hispida from S. bicolor, in which it has sometimes been included. The latter tends to have slightly broader phyllaries and more obviously clavate pappus bristles. The two co-occur in some populations but do not appear to form hybrid swarms with a range in ray corolla color. Three varieties have been described on the basis of growth and pubescence features and are sometimes recognized. These may represent only extremes in continua of variation. Variety lanata has densely villous stems and leaves; such plants occur scattered through much of the range of the species. Two glabrous-stemmed varieties have been described; plants of var. tonsa are relatively small and were first described from Newfoundland; var. huronensis includes relatively tall glabrous plants found growing in sand dunes along the shore of Lake Huron in Michigan and Ontario. The latter plants have been treated as var. tonsa but the name is misapplied. Other varietal names are based on minor variations.

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.
