(2–)4–5(–5.5) × 0.5–0.7 cm, entire or rarely with a pair of sub-basal obtuse teeth (or a single tooth), and 1–2 pairs of linear triangular, subrecurved, entire or subentire lateral segments. Scapes usually 1–3, to ca. 15 cm long, sparsely aranose to aranose below capitulum. Involucre ± rounded at base, ca. 7–9 mm wide; inner phyllaries green to dark green, ca. 12–14 mm long.
