  • Stolons slender, long creeping, sometimes forming a small enlargement at end. Culms solitary at nodes of stolon, distantly arranged in a row, 7-35 cm tall, 0.8-1.2 mm thick, terete, deep green, clothed at base with mostly 2 short sheaths.
  • Sheaths 1-5 cm long, hyaline, obliquely truncate at thin, muticous apex.
  • Inflorescence as a rule a single pseudo-lateral spikelet (very seldom a head with 2 or 3 spikelets); bract erect, 1-5 cm long, subacute at apex. Spikelet lanceolate-oblong to narrowly elliptic, 7-10 mm long, 2.5-3.5 mm wide, terete, acute at both ends, stramineous greenish, densely many-flowered.
  • Glumes oblong or elliptic, 3.8-4.5 mm long, 1.8-2 mm wide, membranaceous, indistinctly severalveined chiefly above middle; keel green, narrow. Achenes obovate to elliptic, 1.7-2.2 mm long, 1.2-1.8 mm wide, plano-convex, cuneate at base, subabruptly contracted to pointed apex, sides maturing brownish, shiny, hardly wrinkled; style 4-5 mm long, 2-celft. Hypogynous bristles 4 or 5, slightly longer than to twice as long as achene, sometimes totally reduced.
  • A distinct species immediately discernible by the one-spiked low culms distantly arranged in a row along long, slender stolons.
