mid and distal cauline sessile, blades elliptic, 15–30 × 5–7 mm, rapidly reduced distally, margins entire.
rosettes present at flowering;
basal and proximal tapering to winged petioles, blades oblanceolate, 70–210 × 8–28 mm, somewhat fleshy (fresh), margins entire, sometimes shallowly crenate or serrate distally, sometimes undulate, apices acute, mucronate or attenuate, glabrous;
mid and distal cauline not crowded, sessile, blades lanceolate to linear-lanceolate, 10–120 × 5–16 mm, reduced distally, margins entire.
1.5–2.5 mm, hispido-villous to canescent.
2–8 mm, glabrous or sparsely strigose;
bracteoles 0–4.
campanulate, 4–6 mm.
narrowly campanulate, 3–4 mm.

6–12;
corollas 3–4.5 mm, lobes 0.6–1.2 mm.
8–22;
corollas 2.5–4.5 mm, lobes 1–1.5 mm.
in 3–4 series, appressed, strongly unequal, midribs and tips conspicuously green, margins white, scarious, apices obtuse, glabrous or moderately strigose.
in 3–4 series, outer narrowly ovate to lanceolate (1.5–3 × 0.4–1 mm), unequal, obtuse to acuminate.
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.
60–100, in thyrsiform-paniculiform arrays, sometimes secund apically, (3.5–)6–26(–60) x 4–10(–15) cm, branches ascending to arching.
(narrowly obconic) 1–2.5 mm, glabrous;
pappi 2.5–4 mm (sometimes distinctly clavate).
(narrowly obconic) 1.5–2.5 mm (ribs 5–8, broad, lighter than body), sparsely strigose;
pappi 3–4 mm.

Solidago hispida
Solidago spectabilis
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.
