Habit | Plants 50–120 cm; rhizomes short, caudexlike. | Plants 50–150 cm; rhizomes creeping, elongated, sparsely scaly. |
Stems | 1–5, sparsely to moderately strigoso-puberulent. |
1–20+, erect (stout), conspicuously spreading-hirsute, at least distally. |
Leaves | basal petioles 3–5 cm, blades oblanceolate or spatulate to ovate or rotund, 2–4 cm (excluding petioles); cauline (numerous) subsessile or sessile, blades elliptic or lance-elliptic to ovate, mid mostly 25–50(–65) × 10–25 mm, distal much reduced; branch leaf petioles 1 mm, blades ovate, 5–15 (excluding petioles) × 2–10 mm. |
basal and proximal cauline usually withering by flowering except on new shoots, tapering to broadly winged petioles, blades oblanceolate, 30–50 × 8–15 mm, rapidly increasing in size distally, margins shallowly serrate, scabroso-strigose, faces often more densely hairy than distal; mid to distal cauline numerous, crowded, sessile, blades lanceolate-ovate to elliptic-oblong, larger ones 35–120 × 8–35 mm, much reduced distally, bases broad and ± clasping, margins obscurely serrulate or entire, faces usually moderately hirsuto-villous on midnerves, often less so abaxially, adaxial sparsely strigose or glabrous. |
Peduncles | linear, 1–3 mm, bracteate. |
2–8 mm, sparsely to moderately strigillose; bracteoles 1–3, linear to linear-lanceolate, tending to group proximal to involucres, sometimes grading into phyllaries. |
Involucres | narrowly campanulate, 3–5 mm. |
narrowly campanulate, 3.5–5.5 mm. |
Ray florets | 0(–2). |
(2–)4–10; laminae 1.2–2.5 × 0.2–0.5 mm. |
Disc florets | 4–8; corollas 3 mm, lobes 1 mm. |
(2–)4–7; corollas 4–5 mm, lobes 0.5–1 mm. |
Phyllaries | in 3–4 series, lanceolate, strongly unequal, margins ciliate, apices acute, glabrous. |
in 4–5 series, unequal, glabrous; outer narrowly ovate-lanceolate, mid and inner linear-lanceolate. |
Heads | 75–200 in open paniculiform arrays, branches divaricate, ascending to recurved, weakly to strongly secund, to 50 cm, secondary branches less than 3 cm. |
35–500, in paniculiform arrays, usually dense, branches recurved-secund. |
Cypselae | 2.5–3 mm, moderately short-strigose; pappi 2 mm. |
(narrowly obconic) 1.5–1.8 mm, sparsely strigillose, sometimes only apically; pappi 3–4 mm. |

Discussion | Solidago brachyphylla possibly occurs also in Mississippi. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Solidago fistulosa grows mainly on the coastal plains. It was introduced at Stone Mountain, Georgia. Solidago pyramidata Pursh may be a synonym of S. fistulosa. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
