Scales 5-7, the lower 2 empty, equalling or nearly as long as the spikelet, the flowering scales very firm, rounded on the back, obscurely 9-nerved, the nerves more prominent at the shortly 3-toothed apex, pilose near the margins, the callus short and obtuse, pilose; palet 2-keeled, ciliate on the keels.
