Ligule up to 4 mm. long, lanceolate-oblong or triangular-oblong, acute to subobtuse, often lacerate.

Panicle 0.9-7.5 cm. long, ovate to oblong or obovate in outline, erect, somewhat contracted or open and loose; rhachis filiform, glabrous, smooth, branches paired or rarely solitary, bearing spikelets in the upper 1/2, very slender, almost capillary. Pedicels 2-10 mm. long, capillary. Spikelets 2.5-4.5 mm. long, ovate to broadly oblong in lateral view, pallid green or silvery-grey, sometimes tinged with purple, slightly glossy. Glumes 2.75-4.5 mm. long, broadly lanceolate, minutely scaberulous along the keel. Lemmas 1.75-2.5 mm. long (excluding the awn), ovate-lanceolate with the apex acute to subobtuse, dorsally asperulous towards the apex; awn 3-4 mm. long, usually brown; callus appressed-pilose.
