Basal leaves sometimes present in rosettes at flowering, proximalmost cauline petiolate, usually withering by flowering, not 3-nerved. Heads in axillary clusters or in terminal thyrsiform arrays, not nodding or secund. Phyllaries sometimes striate, not stipitate-glandular. Pappus bristles usually in 2 series (inner bristles usually moderately clavate).

Distribution

e North America (shaded woods and thickets, eastern deciduous forests).

Discussion

Species 8 (8 in the flora).
