Spikelets: scales of sterile spikelets lanciform, keeled, midrib excurrent at mucro; fertile scales saccate, strongly ribbed, distended by achenes. Flowers: stamens 2; anthers narrowly oblong, 0.5 mm. Achenes pale, lustrous, broadly trigonous-obovoid to subglobose, the fertile 1.5 mm, the sterile 1 mm, faces slightly convex, rugulose, papillose; tubercle a small depressed or conic button. 2n = 20.
