Compact, tufted perennials, often turning brown when dry, c. 0.1-0.4 m tall. Rhizome small; roots thin, numerous. Leaves grass-like, narrowly linear-acuminate, with in-rolled margins to filiform, erect, margins narrowly membranous below, initially with a closed basal sheath, not auriculate. Inflorescence consisting of crowded (rarely solitary) capitula which are sessile, or sometimes on short lateral branchlets, the young heads semiglobose, becoming globose and compact with age, usually exserted on long peduncles; lowest bract leaf-like but reduced; floral bracts small, membranous. Tepals usually dark, 3-4 mm long, outer aristate, inner acute with broad membranous margins, frayed with age. Stamens 6 (3-4), less than half as long as perianth; anthers small. Ovary trilocular, globose; style very short; stigmas red, curling up on top of ovary. Capsule globose, obtuse, tricostate, 3 mm long, firm, shiny brown with wide wavy placentas; seeds minute, 0.25 mm diam., globose, reticulate, ale-coloured with a small black apiculus. Flowering in summer.
