--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>40–150 cm; caudices stout, sometimes with long slender rhizomes. <b>Stems</b> 1–20(–50+), stout, finely puberulent or scabrous-puberulent at least distally. <b>Leaves</b>: basal absent at flowering; cauline sessile to short-petiolate; blades usually lanceolate-elliptic or ovate, sometimes linear-lanceolate, 30–150 × 5–30 mm, thick and firm, margins entire or few toothed, somewhat to much reduced distally, abaxial faces sometimes resinous and shiny, glabrous or strigillose (hairs mostly 0.1–1.4 mm), adaxial glabrous or scabrous. <b>Heads</b> 10–190+ in paniculiform (rarely racemiform) arrays, usually elongate, usually leafy-bracteate, bracts similar to distal leaves but reduced; branches stiffly ascending, not secund, sometimes elongate. <b>Peduncles</b> mostly 2–15 mm, bracteolate, sparsely to densely short hispid-strigose. <b>Involucres</b> campanulate, 4.5–7.5 mm. <b>Phyllaries</b> in 3–4 series, unequal, linear-lanceolate, acute to attenuate, ± squarrose-tipped, glabrous or moderately strigose, sparsely to moderately stipitate-glandular, sometimes viscid. <b>Ray</b> florets (5–)7–9; laminae 3–7 × 1–2 mm. <b>Disc</b> florets (8–)10–16; corollas 4–5 mm, lobes ca. 1–2 mm. <b>Cypselae</b> 3–4 mm, glabrous or glabrate; pappi ca. 4 mm. <b>2n</b> = 18, 36, 54.</span><!--

|discussion=<p><i>Solidago petiolaris</i> is reported from Colorado but that report has not been confirmed. G. L. Nesom (1990j) discussed variation in the species and mapped the distribution. It is variable in leaf and phyllary shape and indument. Although several varieties have often been recognized in floras, the characters used to distinguish them form continua of variation that do not break into distinct groupings. Several general trends are worth noting. Plants in the Ozarks often have very resinous leaves; that does not appear to correlate with phyllary indument traits. Phyllary pubescence varies in a continuous fashion as well, with the numbers and distribution of hairs not breaking into discontinuous ranges. Diploids are known from throughout the range; one report of a tetraploid comes from North Carolina. Two reports of tetraploids from Florida were based on misidentified specimens. Plants with compact short arrays approach <i>S. wrightii</i> in this trait.</p>
