Solidago sect. Solidago

John C. Semple, Rachel E. Cook
Treatment appears in FNA Volume 20. Treatment on page 110. Mentioned on page 108, 109, 112, 117, 119, 125, 130, 134.

Leaves: basal (rosettes) usually withering by flowering; petiole bases or vasculature not persisting on rhizomes; proximalmost cauline petiolate, sometimes present at flowering; proximal and distal sometimes 3-nerved. Heads in ± paniculiform or thyrsiform arrays (wand, club, or secund cone-shaped) or in axillary clusters, sometimes in rounded corymbiform arrays. Phyllaries 1-nerved, usually not striate (3–5-nerved and striate in S. glomerata, S. lancifolia, S. roanensis) sometimes minutely stipitate-glandular, sometimes resinous. Pappus bristles in 2–3 series (shorter, outer setiform scales rarely present, outer, longer bristles apically attenuate, inner bristles longest, weakly to strongly clavate).

Distribution

North America, South America, temperate Eurasia, in tropical Asia

Discussion

Species ca. 95 (71 in the flora).
