Growing in densely tufted, narrow-based clumps. Stems 50—70—(100) cm × 1-1.5 mm, slender, light green, ridged, not shining, pith interrupted, or quite commonly continuous; basal bracts short, closely appressed to the stem, pale grey to light brown; inflorescence very pale, open, never clustered, with numerous flowers evenly spaced along slender, often curved branchlets; tepals 1.5-2 mm long, pale green; stamens 3; capsule 1.5-2 mm long, light brown, almost globose.

Densely tufted; rhizome short. Stems 50-70-(100) cm × 1-1.5 mm, dull blue-green. Inflorescence delicate, always open with flowers evenly spaced along slender often curved branches. Stamens 3. Capsules 1.5-2 mm long, ± = tepals, very pale brown.

Densely tufted, erect, narrow-based clumps. Rhizome 2–3 mm. diam., horizontal. Flowering stems 50–70–(100) cm. × 1–1.5 mm., slender, ridged, not shining, light green, pith interrupted by irregularly shaped lacunae, or quite commonly continuous; lvs 0; basal bracts short, closely appressed to the stem, lower bracts light grey, the upper bracts light brown, paler towards the tip. Infl. apparently lateral, many-fld, open and spreading, branchlets slender, often curved, never clustered. Fls 1.5–2 mm. long, evenly spaced along branchlets of infl., not clustered; tepals pale green with very broad membr. margin. Stamens 3. Capsule 1.5–2 mm. long, ± = or slightly > tepals, trigonous-spherical, almost globose, shining, pale straw-coloured or light brown.
