Description Perennial. Rhizome, stout, up to 11 mm in diameter when dry, horizontal, stoloniferous, bearing overlapping scale leaves. Culms erect, nodeless, 1 - 2 m X 2 - 12 mm (10 mm below inflorescence), terete and spongy about the middle, tapering, firming, becoming more or less trigonous up to inflorescence (never sharply triangular throughout), glabrous. Leaves usually reduced to membranous, greyish-brown sheaths, 2 - 3 per culm, sheath mouth obliquely truncate, margin hyaline, ligule a membranous flap; lamina occasionally developed, 5 - 300 X 3 - 10 mm, flexuous, thin, almost translucent when underwater.
Inflorescence pseudolateral, anthelate, supra-decompound with ± 120 densely arranged spikelets ranging to reduced head-like cluster with ±30 spikelets on shortened rays; peduncles including primary rays stoutish; usually overtopped by terete, sharply pointed bract 20 - 60 (- 90) mm long that continues line of culm. Spikelet shortly pedicelled, ovate-oblong to oblong, 8 - 22 X 2 - 4 mm, lengthening with age when proximal rachilla becomes bare, rust brown. Glumes extreme proximal 1 - 2 sometimes sterile, otherwise fertile, ovate to oblong-ovate, 3.0 - 4.0 X 2.5 - 3.0 mm, concave, opaque, thin, rust brown, apex acute, glume tissue continuous adaxialIy, not notched; mucro minute, recurved, flanked by margins minutely ciliate distally, glabrous proximally. Hypogynous outgrowths 4 - 5, abaxial (rarely + 1 adaxial), slightly exceeding mature achene, pale brown, narrow to medium slender proximally, plumose-fimbriate distally for ± 2/3 of total length. Stamens 3, filaments 0.25 - 0.5 mm wide after anthesis, usually persistent; anthers 1.5 - 2.0 mm including fan-shaped, ciliate crest. Style 1.5 - 2.0 mm; branches 2 ± 3.0 mm long, slightly fimbriate. Achene broadly obovate, plano convex (lacking abaxial ridge) apiculate, 2.3 - 2.7 X 1.3 - 1.7 mm (including apiculus), greyish-brown to greyish-black at maturity, surface smooth. [details]
