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).
