Plants 40–100 cm; caudices densely rooting, branching; vascular-bundles and petiole bases marcescent (attached to old stems for more than a season). Stems 1–10+, erect, slender to stout (tall shoots), glabrous. Leaves: basal often persistent, also present as new rosettes at flowering, tapering to winged petioles to 250 mm, blades narrowly ovate to lanceolate, 50–150 × 15–45 mm, apices obtuse to acute, faces glabrous; proximal cauline similar, reduced distally (petioles becoming less developed); distal sessile, blades prominently 1-nerved, ovate to lanceolate, 75–100 × 8–12 mm, much reduced distally, margins entire, flat, apices acute. Heads 10–500+ in corymbiform arrays, branches glabrous. Peduncles 6.3–8.5 mm, glabrous; bracteoles 3, linear to lanceolate, sometimes grading into phyllaries. Involucres campanulate, 4–5 mm. Phyllaries (14–18) in 3–4 series, broadly linear to ovate, unequal, obtuse, obscurely striate. Ray-florets 6–8; laminae 4.6–5 × 0.5–0.7 mm. Disc-florets 8–20; corollas 4–4.5 mm, lobes 0.6–1 mm. Cypselae (obconic) 1.6–2.2 mm, glabrous; pappi 2.5–3 mm (apically clavate). 2n = 18.

Discussion

Solidago ohioensis is most likely to be confused with S. riddellii, which has folded and multinerved leaves, and S. houghtonii, which has arrays with few large heads. Solidago ohioensis is found in the southwestern Great Lakes area and the flatlands region to the southwest. Hybrids between S. ohioensis and S. ptarmicoides occasionally occur where the two parents are sympatric. Those hybrids were described as S. ×krotkovii B. Boivin [Oligoneuron ×krotkovii (B. Boivin) G. L. Nesom] and can be similar to S. houghtonii.
