Phyllaries in 2-3 series, green or medially rosy purple, often with purple-black spots, midstripe, and/or tips, subequal to unequal, margins glabrous or ± hairy, not usually ciliate, faces glabrous or tomentose, sometimes stipitate-glandular or eglandular; outer erect or spreading, apices adaxially glabrous or hirsuto-villous; inner erect, not notably elongating in fruit. Receptacles epaleate or paleate. Florets 15-150; corollas yellow, tubes 4-18 mm, ligules 6-24 × 2-5 mm; anthers 3-7 mm. Cypselae 7-15 mm, bodies fusiform to narrowly conic, 5-9 mm, tapered to stout beaks 1-4 mm, lengths mostly less than ¹/2 times bodies; ribs flattened to ridged, glabrous, or distally scabrous; pappi in 2-3 series, 8-18 mm. 2n = 18, 36
