Plants
30—120(—200) cm; rhizomes branched, elongate, thick.
Stems
usually 1, erect, glabrous, short hispido-strigose in arrays.
Leaves:
basal and proximal cauline tapering to long petioles that partially sheath stems; blades oblanceolate, 100—350 × 5—60 mm, margins subentire to serrate, apices acute; mid to distal sessile, not sheathing stems, blades lanceolate, 20—50 × 5—10 mm, much reduced distally, margins entire.
Heads
35—230 in elongate paniculiform arrays, sometimes narrow and secund pyramidal, usually narrowly to broadly, non-secund thyrsiform; branches strongly ascending with non-secund heads to arching with heads secund.
Peduncles
1—4 mm, glabrous or sparsely strigose.
Involucres
3—5 mm.
Phyllaries
(14—18) in 3—5 series, unequal, usually apically ciliate; outer ovate, acute, inner linear-oblong, obtuse.
Ray florets
1—8 (moderately conspicuous); laminae 3.2—3.7 × 0.4—0.6 mm.
Disc florets
6—8; corollas 4.6—5 mm, lobes 0.6—1 mm.
Cypselae
1—2 mm, glabrous or sparsely strigillose;
pappi
2.7—3 mm (weakly clavate).

Solidago uliginosa
is highly variable in stem height and the size of the array, which are greatly influenced by growing conditions. A. Cronquist (1980) treated
S. simulans
as a "broad-leaved extreme of
S.
gracillima
, approaching
S.
uliginosa
." These plants come from a distinctive habitat in western North Carolina, south of more typical populations of
S. uliginosa
; it might warrant recognition as a narrowly distributed endemic. In the north, several different tetraploid races within the species appear to be derived separately from diploids in the eastern and the Great Lakes portion of the range.
