Inflorescences: scape sheaths longer than or at least rising above leaves; scapes linear to filiform, distally 0.3–0.4 mm wide, glabrous; mature heads gray or gray-brown, hemispheric, usually globose by seeding time, 2–3.5 mm wide; receptacle densely pilose; involucral bracts soon reflexed, brown, ovate to triangular, 0.5–1 mm, apex acute, surfaces abaxially pilose; receptacular bracts brown, mostly narrowly obovate-cuneate or spatulate, concave, 1–1.5 mm, apex acute, abaxially pilose distally, hairs translucent, club-shaped. Staminate flowers: sepals 3, deep brown, spatulate, 1 mm, apex obtuse, distally pilose, hairs translucent; androphore pale, claviform, as long as sepals; stamens 2, appendages 2.
