Leaf blade linear, somewhat expanded but mostly rolled, tapering to fine tip, dull green but with conspicuous abaxial white ribs, up to 20 cm long but mostly shorter, often withering at apex, base not auriculate - simply rounded and slightly notched, glabrous, rigid and erect but not spine-tipped.

Inflorescence a spicate panicle, narrowly ovate to lanceolate in outline, about 15/2,5 cm. Secondary axis verticillately arranged to main axis, 2,5-4 cm long, glabrous, steeply ascending and adpressed against main axis. Spikelets 2-flowers, lanceolate, 8-10/0, 75-1 mm, paired = 1 sessile; 1 stalked. Glumes membranous, straw-coloured to green or often deep purple-tinted, glabrous, persistent.
