Annual, hydrophyte, up to 500 mm tall. Leaves often overtopping inflorescence, leaf blades 30-500 mm long, 3-8 mm wide. Spikelets 4-7 mm long (including lemma awns). Panicle narrow, interrupted, up to 200 mm long; spikelets clustered into dense, globose aggregations 8-12 mm in diameter and spaced at intervals of 10-25 mm up the axis, sometimes confluent near apex; clusters subtended by 2 to many bracts, each to 12 mm long; glumes 4.5-6.0 mm long; lemmas 3.5-5.0 mm long, including stiff awn; anthers 1-3, 1.5-2.0 mm long.
Annual; culms 5–60 cm. high, erect.. Leaf-blades up to 25 cm. long and 6 mm. wide.. Panicle 3–20 cm. long, the glomerules 5–11 mm. in diameter, often contiguous but scarcely confluent, the bracts usually exceeding the spikelets, up to 10 mm. long, acicular.. Glumes subequal, 4.5–6 mm. long; lemma 3.5–5 mm. long (including awn), acuminate to a short stiff awn-point; palea-wings variously notched; lodicules 1–2; anthers 1–3, 0.3–2.2 mm. long.
Glumes 2.6–4.5 mm long, lanceolate, crispate-hirsute; lemmas 3.6–4.8 mm long (including awn), ovate-lanceolate, acuminate to a short stiff awn-point; palea wings conspicuous and projecting from the sides of the lemma.
Inflorescence 3–14 cm long, the glomerules globular, 5–11 mm in diameter, sometimes contiguous but scarcely confluent, the bracts usually exceeding the spikelets.
Annual up to 60 cm tall, erect; leaf laminas up to 30 cm × 7 mm, glabrous.
