Solidago buckleyi
Solidago patula
Buckley's goldenrod
rough-leaf goldenrod, roundleaf goldenrod, swamp goldenrod
1–5+, sparsely to moderately short strigose or villous.
1–3+, erect (angular in cross section, sometimes winged on angles), glabrous or sparsely hairy in arrays.
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 and proximal cauline abruptly narrowed to long, winged petioles, blades broadly ovate, 100–300 × 40–100 mm, relatively thick, margins serrate, apices acute, abaxially glabrous, adaxially scabrous;
distal cauline sessile, blades lanceolate, 50–80 × 15–20 mm, gradually reduced distally, subentire.
1–6 mm, moderately canescent;
bracteoles linear to lanceolate.
1–4 mm, sparsely hispido-strigose, bracteoles 2–5, lanceolate, grading into phyllaries distally.
campanulate, 4.5–5.5 mm.

laminae 1.5–1.7 × 0.5 mm.
8–14;
corollas 4–5 mm, lobes ca. 1.5 mm.
5–15;
corollas 2.8–3 mm, lobes 0.6–1.5 mm.
in ca. 3 series, strongly unequal, erect to slightly squarrose-tipped, lanceolate, apices acute, glabrate, sparsely to moderately, finely stipitate-glandular.
(10–12) in 3–4 series, ovate to linear-ovate, unequal, obtuse.
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.
25–200, secund, in open, lax, secund, pyramidal, paniculiform arrays, branches ascending to recurved, often elongate with recurved ends.
(reddish brown) 2–3 mm, glabrous;
pappi 4–5 mm.
(sometimes mottled) 1.5–2 mm, strigillose;
pappi 2–3 mm.
Solidago buckleyi
Solidago patula
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.

Subspecies 2 (2 in the flora).
Solidago patula is readily recognized by the angled stem and the sharkskin-like texture of the adaxial surface of the leaves.

1. Plants relatively robust, proximal leaves large, 80–300 × 40–100 mm, sharply serrate; distal leaves relatively few, gradually reduced distally, serrate; n and s in mountains, to Alabama, Mississippi,Georgia | subsp. patula |
1. Plants more slender and small-leaved, proximal leaves narrower, 50–60 mm wide; distal leaves numerous, much reduced to bracts in array, usually finely serrate to entire; mostly coastal plain and adjacent piedmont | subsp. strictula |
