Solidago subsect. Nemorales

Stems and leaves usually moderately to densely strigoso-canescent. Leaves: basal often present in rosettes at flowering, proximalmost cauline petiolate to subpetiolate, sometimes present at flowering, largest sometimes with two prominent lateral nerves (3-nerved). Heads in variously thyrsiform-paniculiform, open to usually congested, cone-shaped, ± secund (to reflexed in S. nemoralis) arrays, proximal branches arching, secund; phyllaries 1-nerved, not stipitate-glandular, not striate. Pappus bristles usually in 2 series (inner usually weakly to moderately clavate).
