usually anise-scented when crushed;
basal and proximal usually withering by flowering, tapering to broadly winged petioles, blades oblanceolate, margins entire, short-strigillose, faces glabrous or short scabroso-strigillose along main nerves;
mid and distal cauline sessile, blades lanceolate to linear-lanceolate or narrowly ovate, 30–110 × 8–20 mm, much reduced distally, bases rounded, margins entire, midnerves prominent, sometimes scabroso-strigillose basally to much of length, apices acute, faces glabrous, finely translucent gland-dotted.
1.5–2.5 mm, hispido-villous to canescent.
thin, 2–8 mm, glabrate to finely puberulent, glabrous strips proximal to few linear-lanceolate bracteoles.

in 3–4 series, strongly unequal, yellowish, acute, glabrous;
outer narrowly ovate to lanceolate, inner lanceolate to linear-lanceolate.
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.
(20–)75–350, in paniculiform arrays, openly secund, pyramidal, proximal to mid branches ascending to spreading, recurved, secund, 3–18 cm.
(narrowly obconic) 1–2.5 mm, glabrous;
pappi 2.5–4 mm (sometimes distinctly clavate).

Solidago hispida
Solidago odora
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.
