Solidago hispida
Solidago drummondii
hairy goldenrod, verge d'or hispide
Drummond's goldenrod
1(–5), erect, simple, glabrous or moderately to densely hispido-villous, sometimes hairs appressed.
usually 1, ascending to erect, uniformly short villoso-strigose, occasionally glabrate proximally.
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 and proximal cauline short-petiolate, blades broadly ovate or elliptic-ovate, margins serrate, ± 3-nerved and pinnately nerved, abaxial faces (at least) evenly short villoso-strigose;
mid and distal cauline like proximal, 20–70 × 10–40 mm (1.3–2 times as long as wide), usually only those near arrays reduced and 1-nerved.
1.5–2.5 mm, hispido-villous to canescent.
1–6 mm;
bracteoles ovate, minute, grading into phyllaries.
campanulate, 4–6 mm.
campanulate, 3–4.5 mm.
6–14;
laminae 1.5–4.5 × 0.5–1 mm.
3–7;
laminae 1.5–2 × 0.5–1 mm.
6–12;
corollas 3–4.5 mm, lobes 0.6–1.2 mm.
4–7;
corollas (abruptly ampliate) 3–3.5 mm, lobes ca. 1 mm.
in 3–4 series, appressed, strongly unequal, midribs and tips conspicuously green, margins white, scarious, apices obtuse, glabrous or moderately strigose.
in 3 series, strongly unequal, obtuse or rounded;
mid broadly oblong, inner narrowly so.
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.
30–200+, apparently sometimes drooping, in open leafy, secund pyramidal, paniculiform arrays, branches recurved, leafy-bracteate, secund, proximalmost branch sometimes separated by several nodes from next.
(narrowly obconic) 1–2.5 mm, glabrous;
pappi 2.5–4 mm (sometimes distinctly clavate).
1.5–2 mm (4–8 translucent ribs), moderately short-strigose;
pappi 2–2.5 mm.

Solidago hispida
Solidago drummondii
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.

A. Cronquist (1980) listed Solidago drummondii as reputedly in Louisiana; K. N. Gandhi and R. D. Thomas (1989) did not see any specimen from that state.
