Herbs, perennial, cespitose, floriferous culm 0.5–3 dm. Culms first ascending, soon arcuate-stoloniferous and creeping or floating, or growing submersed along bottom, each node with cluster of basal leaves and fibrous roots, eventually each emergent terrestrial node with floriferous culm. Leaves basal; auricles 0.5–1 mm, apex acutish, membranous or thicker; blade spreading, flat, 2–10(–15) cm × 1–3 mm. Inflorescences glomerules, (1–)2–10, each with 3–12 flowers, open; primary bract usually shorter than inflorescence. Flowers: tepals green, margins scarious; inner series narrowly lanceolate, 5–9 mm, apex usually recurved; outer series obviously shorter, apex usually erect; stamens 3, filaments 1.5–3 mm, anthers 0.5–0.8 mm; style 0.5 mm. Capsules tan, 3-locular, narrowly ellipsoid, 3.5–5.5 × 0.8–1.2 mm. Seeds brown, ovoid, 0.3–0.4 mm, not tailed.
