Rootstock erect. Leaf blades 1–15 cm × 0.5–3 mm, base 1- or ± 3-veined, faces glabrous or hairy. Scapes erect, 2–60 cm, glabrous or hairy. Inflorescences: involucral sheath 5–32 mm; outermost involucral bract ovate to triangular-lanceolate, 4–14 mm, shorter than, equaling, or exceeding head, mucronate or not; heads 13–28 mm diam. Flowers monomorphic, with all stigmas papillate and pollen reticulate, or dimorphic, with papillate stigmas and finely reticulate pollen or smooth stigmas and coarsely reticulate pollen; calyx tube hairy on and between ribs (holotrichous), on ribs only (pleurotrichous), or glabrous (atrichous); teeth triangular to shallowly triangular, awned or not; corolla pink to white; petals showy and exceeding calyx or reduced and included in calyx. 2n = 18.
