Sect. Glaucae: Not or laxly caespitose; rhizomes creeping. Male spikes cylindrical, dense to lax; lowest bract leaf-like, c. as long as inflorescence. Utricles often flattened, membranous, inflated, ± veinless, papillose to scabridulous, abruptly narrowed into a minute, ± truncate beak. Stigmas 3.
Not or laxly caespitose; rhizomes long, far-creeping. Stems 10-70(-90) cm, subterete to bluntly trigonous, usually smooth; basal sheaths purplish-brown or very dark brown, not fibrous. Leaves 1.5-6 mm broad, shorter than stems, rather rigid, glaucous beneath, dull green above, often curved, flat to channelled, margins often involute. Male spikes 1-3, approximate, terminal longest, 1.5-6.5 cm. Female spikes 1-4(-5), 1.5-6.5 cm, rather distant but often overlapping, erect to pendent, dense to lax; peduncles to 3 cm, often scabrid; lowest bract equalling or exceeding inflorescence; sheath obsolete (to 5 mm).
