Inflorescence composed of paired racemes, the pairs each subtended by a spatheole and gathered into a scanty false panicle; racemes short, the superior borne on a very long raceme-base, its basal spikelets at ± the same level as the apex of the inferior raceme, the two thus appearing to be arranged end-to-end, each raceme with 2 homogamous spikelet pairs; pedicels linear.
Sessile spikelet terete; callus pungent, applied obliquely; inferior glume subcoriaceous with a herbaceous beak 2–3 mm long, rounded on the back and sides; superior glume awnless; inferior floret reduced to a hyaline lemma; superior lemma hyaline, bidentate, passing between the teeth into an awn with pubescent column.
Ligule scarious, adnate to the sheath-auricles; leaf laminas linear.
Pedicelled spikelet male, without a distinct callus.
Caryopsis narrowly oblong.
Perennial.
