Description Erect aquatic perennial, with culms closely packed on a tough rhizome. Culms terete, 90–200 cm long, 3–7 mm diam. about halfway along its length, pluritubulose, rarely unitubulose above (transverse septa not obvious externally when fresh), glabrous, longitudinally finely striate but not verruculose, mid-green. Lower leaves reduced to sheaths; upper leaf blades terete, to 180 cm long, shorter than culms, about same diameter as culms, pluritubulose, rarely unitubulose above; sheaths loose, pale brown at maturity, to 30 cm long, variably septate-nodulose on adaxial surface. Lowest inflorescence bract erect, appearing continuous with culm, 12–40 cm long, pluritubulose or rarely unitubulose, septa not visible externally; margins of the base of this bract and of several much smaller inflorescence bracts above the lowest hyaline to yellow-chartaceous, not or faintly red-dotted, slightly enlarged but not strongly sheathing inflorescence. Inflorescence pseudolateral, hemispherical to globose or ellipsoid, dense, 10–24 mm long, 7–15 mm diam., with numerous pseudospikelets; core raised-ellipsoid to ovoid or hemispherical. Pseudospikelets with several sterile glumes at the base, c. 10–16-flowered, flowers all male except for uppermost, which is female. Glumes spirally arranged, 3.5–5.0 mm long, to 1.5 mm wide, spathulate to nearly linear, thin-textured, whitish near their base, pale brown to red-brown in upper half and with narrow whitish band at apex, glabrous, at least several lower glumes keeled near apex; apex more or less praemorse, obtuse to acute. Stamen 1 per flower; anther 1.5–2.2 mm long, excluding apical appendage 0.1–0.3 mm long. Style 3–5-fid, white when fresh. Fruit (only seen immature) obovoid, with 8–12 longitudinal ridges, with faint and irregular transverse ridges, tough, c. 3.5 mm long, c. 1.8 mm diam., dull red-brown. [details]
