20–500, secund, in paniculiform arrays, secund-pyramidal to broadly club-shaped, sometimes leafy proximally, at least proximal branches spreading-recurved, branches and peduncles bracteolate, bracteoles reduced distally.
5–160 (2–10+ more per short branch cluster), in narrowly elongate paniculiform arrays, branches usually 1–6 cm (much longer in damaged plants, sometimes 1–3 proximal branches much elongated in undamaged plants), ascending and bearing short terminal racemiform or paniculiform clusters.

Solidago sempervirens
Solidago buckleyi
Subspecies 2 (2 in the flora).
Solidago sempervirens is common along the seacoast from the Gulf of St. Lawrence to central America and the northern West Indies. Introduced populations are sometimes very large near the Detroit River and Lake Erie in southwestern Ontario, eastern Michigan, and adjacent Ohio. A second disjunct group of populations occurs in Illinois and Indiana in the Chicago area at the southern end of Lake Michigan. Two mostly geographically separate subspecies can be recognized in the flora range. A race also occurs in the Azores and is undoubtedly introduced there [Solidago sempervirens var. azorica (Hochstetter ex Seubert) H. St. John]. Plants cultivated in European gardens have been labeled S. sempervirens var. viminea (Aiton) A. Gray.

Solidago buckleyi is an uncommon species of mesic woods, most variable in the size and number of teeth on the large mid cauline leaves. Once seen, usually it is not easily confused with S. petiolaris. Reports from farther east are for plants of S. petiolaris.
