Herbs, perennial, densely cespitose, forming rosettes, 5--15 cm. Leaves linear or linear-triangular, mostly 0.5--2 cm, apex narrowly acute to acute, rarely blunt. 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. Pistillate flowers: sepals 2, pale, broadly spatulate to narrowly oblong-obovate, concave, oblique, keeled, 1 mm, apex obtuse, apex ciliate, abaxially pilose distally, hairs translucent; gynoecium 2-carpellate; styles apically dilated, apex 2-cleft, appendages 2, deeply 2-cleft.
