Characteristics

Plants perennial, submerged. Rhizome slender to robust, terete, usually developing apical buds. Stems sparsely to densely branched, filiform to slender, terete, 0.5-4 mm in diam. Stipules partly fused with leaf base and sheathing stem; sheaths 1-6.5 cm, convolute, appearing as a short spiral when transversely dissected, persistent, usually green with greenish to pale brownish margins; leaves sessile, usually olive-green to dark green, mostly ± straight, filiform to linear, 2-12 cm × 0.2-4 mm, 3-5-veined, lateral veins inconspicuous, usually with air channels bordering midvein, apex acuminate to acute, occasionally obtuse or rounded with short mucro. Spikes cylindric, 1-6 cm, with 3-7 whorls of opposite flowers, contiguous at first, later inconspicuously or conspicuously distant; peduncles elongated, slender, ca. as thick as stem. Carpels 4. Fruit obovoid, 3.4-4.2 mm, abaxial keel indistinct, with short beak. Fl. and fr. May-Oct. 2n = 78.
More
Stems branched, especially distally, terete to slightly compressed, to 75 cm. Leaves: those of main stem only slightly larger than those of branches; stipules with stipular sheaths not inflated, 0.8--1.1 cm, ligule 0.8 mm; blade linear, 5.6--9.2 cm ´ 0.2--1 mm, apex acute to mucronate or apiculate; veins 1--3. Inflorescences: peduncles terminal or axillary, erect to ascending, cylindric, 4.5--11.4 cm; spikes moniliform to cylindric, 14--22 mm; verticels 3--5.
